“Large-difference annulus” is a common characteristic encountered in complex wellbore structures with “varying diameters” during (ultra-)deep well drilling. This characteristic leads to slow drilling fluid velocity in the upper large-diameter annulus, posing challenges for cuttings removal, while the higher velocity in the lower small-diameter annulus results in significant circulating pressure loss. To address these issues, a novel flow diverter tool was designed to carry cuttings in the upper section and the loss of circulating pressure in the lower section. However, the lack of a specific wellbore flow model tailored for this tool in current research has hindered its design and optimization. Based on the fundamental principles of fluid flow and hear transfer, a valid mathematical model was proposed to be compatible with the flow diverter tool. Then, via a case study on Well ZS102, the tool was proved to be effective and perform well in practice. The results show that with the installation of the flow diverter tool, the bottomhole pressure is lowered from 85.08 MPa to 80.30 MPa, the standpipe pressure is significantly reduced from 20.97 MPa to 7.22 MPa, and the annulus pressure loss is decreased from 7.16 MPa to 2.40 MPa. The research presents a novel approach for optimizing cuttings removal parameters and preventing leaks in complex wellbore structures during deep and ultra-deep well drilling operations, contributing significantly to the advancement of related drilling technologies.

在深井、超深井钻井过程中常出现“大小井眼”的复杂井身结构,即“大差异环空”井筒。上部大尺寸环空钻井液流速过慢,导致携岩困难;而下部小尺寸环空流速则过快,显著增加了循环压耗。为了解决上述问题,提出了一种新型分流工具,旨在实现“上能携岩,下能降耗”的功能。然而,目前尚缺乏针对该工具的井筒流动数学模型,影响了分流工具结构的设计与优化。基于此,依据流动与传热基本原理,建立了适用于分流工具的井筒流动数学模型,并以ZS102井为例,证实了工具的应用效果。结果表明:安装分流工具后,井底压力从85.08 MPa降至80.30 MPa,立压从20.97 MPa大幅降至7.22 MPa,环空压耗从7.16 MPa降至2.40 MPa。研究结果为深井、超深井钻井作业中复杂井身结构携岩参数优化及防漏治漏提供了新的解决方案,对深井、超深井钻井技术发展具有重要意义。

在深井、超深井钻井过程中常出现“大小井眼”的复杂井身结构,即“大差异环空”井筒。上部大尺寸环空钻井液流速过慢,导致携岩困难;而下部小尺寸环空流速则过快,显著增加了循环压耗。为了解决上述问题,提出了一种新型分流工具,旨在实现“上能携岩,下能降耗”的功能。然而,目前尚缺乏针对该工具的井筒流动数学模型,影响了分流工具结构的设计与优化。基于此,依据流动与传热基本原理,建立了适用于分流工具的井筒流动数学模型,并以ZS102井为例,证实了工具的应用效果。结果表明:安装分流工具后,井底压力从85.08 MPa降至80.30 MPa,立压从20.97 MPa大幅降至7.22 MPa,环空压耗从7.16 MPa降至2.40 MPa。研究结果为深井、超深井钻井作业中复杂井身结构携岩参数优化及防漏治漏提供了新的解决方案,对深井、超深井钻井技术发展具有重要意义。

“Large-difference annulus” is a common characteristic encountered in complex wellbore structures with “varying diameters” during (ultra-)deep well drilling. This characteristic leads to slow drilling fluid velocity in the upper large-diameter annulus, posing challenges for cuttings removal, while the higher velocity in the lower small-diameter annulus results in significant circulating pressure loss. To address these issues, a novel flow diverter tool was designed to carry cuttings in the upper section and the loss of circulating pressure in the lower section. However, the lack of a specific wellbore flow model tailored for this tool in current research has hindered its design and optimization. Based on the fundamental principles of fluid flow and hear transfer, a valid mathematical model was proposed to be compatible with the flow diverter tool. Then, via a case study on Well ZS102, the tool was proved to be effective and perform well in practice. The results show that with the installation of the flow diverter tool, the bottomhole pressure is lowered from 85.08 MPa to 80.30 MPa, the standpipe pressure is significantly reduced from 20.97 MPa to 7.22 MPa, and the annulus pressure loss is decreased from 7.16 MPa to 2.40 MPa. The research presents a novel approach for optimizing cuttings removal parameters and preventing leaks in complex wellbore structures during deep and ultra-deep well drilling operations, contributing significantly to the advancement of related drilling technologies.

相较于中国西部其余三大含油气盆地,四川盆地的海相碳酸盐岩地层呈现出沉积时间更长、地层层系更多、地层厚度更大、油气储藏埋藏更深的特征[1]。如何高效、安全建井,是超深层油气资源勘探开发面临的核心问题。
目前蓬莱气区超深井多采用尾管回接方式中完[2]。尾管回接后环空尺寸减小,导致环空压耗增大,进而造成泵压过高,超出了泥浆泵的额定功率阈值,从而对泥浆泵的安全稳定运行构成了潜在威胁。为了降低泵压,只能降低钻井液排量,却影响了携岩效率而导致沉砂卡钻。为了解决此类问题,现场采取的措施是不回接尾管而直接进行下一开次钻进,形成了上部环空尺寸大、下部环空尺寸小的“大小井眼”的复杂井身结构,即“大差异环空”井筒。尽管此类复杂井身结构设计能够有效地降低泵压,但仍存在环空钻井液流速分配不均的情况。增大钻井液流量则井筒循环压耗增加,减小钻井液流量则上部大尺寸环空携岩困难。因此,提出了一种适用于大差异环空井身结构的钻井液流量分配工具,并建立了基于该工具的井筒流动数学模型,对深井、超深井钻井技术发展具有重要意义。
针对深井、超深井钻井井筒流动模型,国内外学者开展了一系列的研究。孔祥伟等[3]建立了分流器的串联局部压力模型,推导出分流器开口面积的一元二次方程,优化了分流器的最佳携岩位置,并对其进行编程计算;Xu等[4]在前人模型基础上,提出了一种考虑黏度、密度及焦-汤效应随压力和温度变化的半解析模型,并计算稳态流体流动时井筒流体温度剖面的解析模型;张瑞凇等[5]综合井筒传热学和水力学理论,提出了基于反演算法的循环摩阻系数优化方法,建立了考虑温压耦合的高密度钻井液井筒温度场、压力场计算模型;郑友志等[6]建立了定向井井筒-地层瞬态二维传热模型与温度压力耦合下的井筒压力计算模型,评价了温度压力耦合下井筒压力与动静态密度随井深的分布变化特征;王刚等[7]提出一种通过在井筒变径处钻杆上安装分流短节,实现钻井液双循环的方法,基于钻井水力参数优化理论和数值模拟方法,研究分流短节对井筒变径处环空钻井液返速、钻井水力参数和钻杆结构安全性的影响;邓虎等[8]针对超深井井筒流体高温、高压流变特性展开研究,基于漂移流模型建立了一套超深井全井筒复杂流动数学模型,该模型计算出的立压和套压数据与现场作业测得的数据基本吻合,计算精度较高;张锐尧等[9]根据双梯度钻井(controlled mud level dual gradient drilling,CML)的工艺特点与钻井液循环流动特征,建立了井筒温度场和压力场物理模型以及瞬态井筒温压耦合场数学模型,利用有限差分和循环迭代方法对模型进行离散和求解;Chen等[10]提出了一个井筒温度和压力场的完全瞬态耦合预测模型,并考虑了循环流体的热物理性质,提出了一种井筒温度和压强轴向和径向耦合解的双循环迭代算法;柳贡慧等[11]通过开展温度为20~220 ℃、压力为0.1~200 MPa的水基钻井液和油基钻井液流变性测试实验,提出了不同温度和压力范围内的钻井液分段流变模式优选方法,建立了考虑多因素综合影响的钻井井筒压力精确预测模型;刘平江等[12]基于能量守恒原理,建立了井筒温度计算模型,考虑流体流态对温度压力影响,建立了温压耦合条件下井筒压力计算方法,结合现场实测数据验证了温度压力模型计算可靠性。以上研究表明,虽然目前深井、超深井钻井井筒流动数学模型已较为全面,但在应对大差异环空场景,特别是涉及钻井液分流这一复杂的定解条件时,尚未构建出一套能够有效描述和精确预测井筒流动特性的数学模型。这一现状表明,在特定复杂钻井环境下的井筒流动模型仍存在缺陷。
因此,现基于流动与传热基本原理,从改变环空钻井液流量角度出发,结合临界携岩流量与串并联管路理论,设计一种既能确保有效携岩又能显著降低循环压耗的分流工具,并建立基于该工具的井筒流动数学模型。以ZS102井为例,通过对比分析分流前后的井筒压力与温度变化,充分验证该工具实际应用效果,以期为深井、超深井钻井作业中复杂井身结构携岩参数优化及防漏治漏提供新的解决方案。
图1所示,分流工具两端与钻杆螺旋连接,分流孔处于关闭状态,随钻进入井内。当到达指定位置时(即大差异环空井筒的套管变径处),从井口输入压力脉冲信号,压力传感器接收到脉冲信号后,将压力波数据发送电控系统,电控系统带动液压泵工作,通过油液驱动活塞下行并压缩与之相连的弹簧,带动工具内外腔旁通孔连通,从而打开分流孔。
相较于传统的钻井流动过程,钻井液泵入钻杆后,一部分通过分流工具直接进入环空参与循环,另一部分继续沿钻杆继续往下,最后由钻头喷嘴喷出进入环空,在环空中形成了两段不同流量的钻井液,能够满足上部大环空携岩要求,降低下部小环空循环压耗。

目前在钻井工程中对井筒温度场的研究中,通常将钻井液的密度、流变性、导热系数等热物性参数视为恒定值。而在实际钻井过程中,随着井深的增加,地层温度不断上升,特别是深井、超深井中井口温度与井底温度相差较大,对钻井液的热物性参数也有较大影响,为了提高所提模型的准确性,对钻井液的热物性参数随温压变化纳入考虑。
1)密度
钻井液的密度随着温压变化,根据文献调研[14-17],结合钻井液密度随温度压力变化关系式一般的拟合方法,选择模型对所测密度数据进行拟合,表达式为
ρ(P,t)=ρ0exp(ξpP+ξppP2+ξtt+ξttt2+ξptPt)
式(13)中:ρ(P,t)为某温度和压力下的钻井液密度,g/cm3;ρ0初始温度压力条件下钻井液初始密度,g/cm3;P为测点压力,MPa;t为测点温度,℃;ξp=3.800×10-4ξpp=-4.226×10-7ξt=-8.625×10-4ξtt=6.613×10-6ξpt=3.622×10-6
2)流变性
赫巴模式能够对更为复杂的流体流变性进行准确描述。赫巴流体的剪切速率和黏度之间存在着非线性关系,并且常用于描述非牛顿流体模型,能够用于更广泛的流体流变性描述。
赫巴流体的剪切应力τ与剪切速率γ之间的关系式为
τ=τ0+n
式(14)中:τ0为屈服应力,Pa;K为稠度系数,Pa·sn,n为流性指数。
利用式(15)~式(17)[18]可较为准确地描述在赫巴模式下的钻井液随温压变化的流变性,进一步提高模型精度。
τ0 1 t , P=A1 1 t+B1P+C1 1 t 2+D1 P t+E1P2+F1 1 t 3+G1 P t 2+H1 P 2 t+I1P3
K 1 t , P=A2 1 t+B2P+C2 1 t 2+D2 P t+E2P2+F2 1 t 3+G2 P t 2+H2 P 2 t+I2P3
n(lnt,P)=A3lnt+B3P+C3ln2t+D3Plnt+E3P2+F3ln3t+G3Pln2t+H3P2lnt+I3P3
式中:t为温度,℃;P为压力,MPa;τ0(1/t,P)为该温压下钻井液的屈服应力,Pa;K(1/t,P)为该温压下钻井液稠度系数,Pa·sn,n为该温压下钻井液的流性指数;AiBiCiDiEiFiGiHiIi为钻井液流变参数预测模型决定系数,通过实验确定,其值如表1所示。
3)导热系数与比热
根据经验公式[19]来计算钻井液的导热系数及比热与温度的关系,表达式如下。
λp=a1+a2T+a3T1.5+a4T2+a5T0.5
cp=b1+b2T+b3T1.5+b4T2+b5T0.5

根据钻井过程中的能量传递过程,即式(3)、式(5)、式(7)及式(11)中的热源项SpLSaL,包括流动摩阻生热、钻头节流压降生热、钻头破碎岩石生热及钻杆与井壁的机械摩擦生热等。
1)流动摩阻生热源项
钻井液在流道内流动过程中,因其黏性导致部分机械能损失,最终转化为热能,根据流体力学基本原理,钻杆内的摩阻生热源项为
SpfL= 8 f p q m p 3 π 2 d p i 5 ρ p 2
2)环空内的摩阻生热源项
采用Xiao[20]模型,表达式为
SafL= 8 f a q m a 3 π 2 ( d a i - d p o ) ( d a i 2 - d p o 2 ) ρ a 2
钻井液通过钻头喷嘴产生较大的节流压降,这部分节流压降也将转化为热能,成为钻头节流压降生热源项,表达式为
SbL= 0.8 q m a 3 C d 2 π 2 d n e 5 ρ 2 p L
3)机械摩擦生热源项
钻柱在钻井过程中,钻杆发生偏心并与井壁产生机械摩擦,机械摩擦转化为热能是环空钻井液的热源之一。在一般钻进过程中,通常采用旋转钻进和滑动这两种钻进方式。两种钻进方式的技术原理具有明显区别,其产生的摩擦热源项计算也不同。
针对旋转钻进时钻杆与井壁之间的机械摩擦生热可用Kumar公式[21]计算,表达式为
SamL=Tpipeω
Tpipe=Cm d p o 2 1 - ρ a ( d a i 2 - d p o 2 ) - ρ a d p i 2 ρ p i p e ( d a i 2 - d p o 2 - d p i 2 )×wpipeΔLsinθ
式中:SamL为机械摩擦生热源项,W/m;Tpipe为钻杆扭矩,kN/m;Cm为机械摩擦因数,套管内为0.26,裸眼内为0.4;wpipe为空气中单位长度钻杆重量,kN/m;ΔL为钻杆长度,m。
4)钻头破碎地层生热源项
岩体破碎过程实质上是一种内能耗散现象,钻头破碎地层生热源项[22]
Sbit= 1 J(1-η)(WOB·ROP+2πωTbit)
式(25)中:J为焦耳常数,与所做的功和发热有关;η为钻头效率,取0.15;WOB为钻压,kN;ROP为钻速,m/s;Tbit为钻头上的扭矩,kN/m。
(1)钻杆入口温度。进入钻杆的钻井液温度始终保持不变,即
T 0 p , 0= T p , 0 1= T p , 0 2=…= T p , 0 n=Tp,0
式(26)中:T0 p,0T1 p,0T2 p,0、…、T n p,0为任意时间步长钻杆的入口温度,℃; T p , 0为钻杆入口温度,℃。
(2)环空出口压力。由于环空出口与大气直接接触,其出口压力始终为大气压,即
p 0 a , 0= p a , 0 1= p a , 0 2=…= p a , 0 n=pa,0
式(27)中:p0 a,0p1 a,0p2 a,0、…、pn a,0为任意时间步长钻杆的入口压力,Pa;pa,0为钻杆入口压力,Pa。
(3)井底温度和井底压力。钻杆内钻井液的温度和压力与环空钻井液的温度和压力相同,即
T 0 p , L = T 0 a , L , T p , L 1 = T 1 a , L , T p , L 2 = T p , L 2 , , T p , L n = T a , L n p 0 p , L = p 0 a , L , p p , L 1 = p 1 a , L , p p , L 2 = p p , L 2 , , p p , L n = p a , L n
式(28)中: T p , L 0 T p , L 1 T p , L 2、…、T n p,L为钻井液在井底的钻杆内温度,℃;T0 a,L T a , L 1 T a , L 2、…、Tn a,L为钻井液在井底的环空内压力,Pa;p0 p,Lp1 p,L p p , L 2、…、pn p,L为钻井液在井底的钻杆内温度,℃;p0 a,L p a , L 1 p a , L 2、…、p n a,L为钻井液在井底的环空内压力,Pa。
(4)流量分配关系。根据质量守恒定律,泵入井筒的钻井液流量应与钻井液出口流量一致,等于分流工具分流量与小环空钻井液流量,即
qmp1=qma1=qmp2+qmf=qma2+qmf
式(29)中:qmp1为泵入钻杆的钻井液总流量,L/s;qma1为环空出口的钻井液总流量,L/s;qmp2为经过分流工具继续沿钻杆向下的钻井液流量,L/s;qma2为经过分流工具后由钻头喷嘴喷出的钻井液流量,L/s;qmf为经过分流工具进入到环空中的钻井液流量,L/s。
钻井开始时井筒内的温度和压力分布称为初始条件。因此,地层温度可作为初始井筒温度,而静液柱压力可作为初始井筒压力,即
T 0 p , i = T 0 a , i = T 0 g , i p 0 p , i = p 0 a , i = ρ p g H i
式(30)中: T 0 g , i为任意位置的初始地层温度,℃;ρp为钻杆内钻井液密度,g/cm3;Hi为任意位置的深度,m。
对井深为H的水平井进行分割,按照长度Δz分成i个微元体(z方向与井筒轴线一致),可对井筒划分为i个网格,如图2所示。网格的数量可由式(31)确定,表达式为
i= H Δ z
式(31)中:H为水平井井深,m;Δz为沿井深的空间步长,m。
根据数值求解的稳定性要求划定时间步长Δt,迭代n步,即
n= t n Δ t
式(32)中:tn为总迭代时间,s;Δt为时间步长,s。
耦合了压力、温度及钻井液物性参数,利用控制容积法对深井大差异环空钻井井筒流动模型进行数值求解。
(1)钻杆内流体温度分布。
$\begin{array}{l} {\left[\frac{\frac{\pi}{4} d_{\mathrm{pi}}^{2}(c \rho)_{\mathrm{p}, i}^{n+1}}{\Delta t}+\frac{1}{R_{1 \mathrm{~L}}}-\frac{q_{\mathrm{mp}} c_{\mathrm{p}, i}^{n+1}}{\Delta l}\right] T_{\mathrm{p}, i}^{n+1}-} \\ \quad \frac{\frac{\pi}{4} d_{\mathrm{pi}}^{2}(c \rho)_{\mathrm{p}, i}^{n}}{\Delta t}-\frac{1}{R_{1 \mathrm{~L}}} T_{\mathrm{a}, i}^{n+1}+\frac{q_{\mathrm{mp}} c_{\mathrm{p}, i-1}^{n+1}}{\Delta l} T_{\mathrm{p}, i-1}^{n+1}=S_{\mathrm{pL}}^{n+1} \end{array} $
(2)环空内流体温度分布。
$\begin{array}{c} {\left[\frac{\frac{\pi}{4}\left(d_{\mathrm{ai}}^{2}-d_{\mathrm{po}}^{2}\right)(c \rho)_{\mathrm{a}, i}^{n+1}}{\Delta t}+\frac{1}{R_{\mathrm{LL}}}+\frac{1}{R_{2 \mathrm{~L}}}-\frac{q_{\mathrm{ma}} c_{\mathrm{a}, i}^{n+1}}{\Delta l}\right] T_{\mathrm{a}, i}^{n+1}-} \\ \quad \frac{\frac{\pi}{4}\left(d_{\mathrm{ai}}^{2}-d_{\mathrm{po}}^{2}\right)(c \rho)_{\mathrm{a}, i}^{n}}{\Delta t} T_{\mathrm{a}, i}^{n}-\frac{1}{R_{1 \mathrm{~L}}} T_{\mathrm{p}, i}^{n+1}+ \\ \quad \frac{q_{\mathrm{ma}} c_{\mathrm{a}, i-1}^{n+1}}{\Delta l} T_{\mathrm{a}, i-1}^{n+1}=S_{\mathrm{aL}}^{n+1}+\frac{T_{\mathrm{g}, i}^{n+1}}{R_{2 \mathrm{~L}}} \end{array} $
(3)钻杆内流体压力分布。

其计算流程如图3所示,计算步骤如下。
(1)输入井身结构、钻具组合、钻井参数及边界条件。
(2)确定网格尺寸及时间步长。
(3)假设温度及压力的初始分布。
(4)利用物性参数定量描述模型确定初始时刻各网格的物性参数并求出各项热阻。

ZS102井是典型的大差异环空深井,全长6 309 m。在该井钻探作业完成后,现场开展了泵冲实验,测试了5种不同工况下立压、套压、环空循环摩阻等数据。利用ZS102井的实验数据验证上述模型。
ZS102井的井身结构参数如表2所示,其为典型的大差异环空井身结构。
开采用的钻具组合为:Φ149.2 mm牙轮钻头+旋转导向工具+双母接头Φ127 mm+压力计Φ127 mm+311×HT38接头+HT38公×310转换接头+扶正器+Φ127 mm随钻震击器×1个+Φ101.6 mm加重钻杆×75.75 m+Φ127 mm钻杆×3 314.4 m+Φ101.6 mm×2 702.38 m。
当钻进至第五开次(即5 992 m处)时,开始采用不回接尾管的方式继续钻进,此时在井筒3 356 m位置出现大差异环空井身结构:上部大环空尺寸为219.07 mm,下部小尺寸环空尺寸为151.26 mm,大小环空尺寸相差67.81 mm。
ZS102井钻头在6 281.14 m处的泵冲实验结果如表3所示。
此外,测得入口温度为48 ℃,出口温度为53 ℃。
基于所构建的模型,结合ZS102井的具体井身结构、钻具组合配置、实验期间的钻井参数以及钻井液的性能特性,选取套压与入口温度作为评估指标,并以第3种工况(入口流量13.33 L/s)为例,计算得到全井筒温度压力剖面如图4所示。
特别的,计算的立压为14.20 MPa,实测为14.28 MPa;计算的出口温度为51.72 ℃,实测为53 ℃;计算的环空循环压耗为4.95 MPa,实测为5.02 MPa,实测数据和计算数据基本吻合。
各种工况下计算的环空循环压耗及实测的环空循环对比情况如图5图6所示。
图5图6可知,在相同工况条件下,实测立压、环空循环压耗误差均在本文模型计算值的10%以内。
因此,本文模型具有足够的精度对井筒的压力和温度剖面进行预测,为压力剖面调节工具的设计提供了理论基础。
临界携岩流量是指钻井液将岩屑顺利携带出的最小环空钻井液流量,用Qmin表示。工程中,当岩屑的输送比大于或等于0.5就可以算出钻井液安全钻井的最小携岩流量,能满足基本的井眼净化要求,即
Rt=1- V s V≥0.5
式(37)中:Rt为岩屑的输送比;Vs为岩屑沉降速度,m/s;V为环空返速,m/s。
首先明确环空的钻井液是何流态,如果岩屑颗粒周围钻井液的流态不同,岩屑颗粒的沉降速度与之不同,通常会使用岩屑颗粒的雷诺数Re来判别钻井液的流态。
Re= 100 ρ l V s d s η
所以,在不同的钻井液流态的情况下,岩屑沉降速度为
Vs= 326800 d s 2 ( ρ s - ρ l ) η , R e 3 7.13 d s ( ρ s - ρ l ) 0.667 ( ρ l η ) 0.333 , 3 < R e < 300 2.95 d s ( ρ s - ρ l ) ( ρ l ) 0.5 , R e 300
式中:ρl为钻井液密度,g/cm3;Vs为沉降速度,m/s;ds为岩屑尺寸直径,m;η为钻井液有效黏度,mPa·s;ρs为岩屑颗粒密度,g/cm3
要满足井眼清洁,临界环空返速Vmin要满足条件为
V 2 V s V m i n = 2 V s
临界携岩流量Qmin则为
Qmin=AVmin
式中:Vmin为临界环空返速,m/s;Qmin为临界携岩流量,L/s;A为环空当量面积,m2
据钻井资料,ZS102井的岩屑平均直径为8 mm,如图7所示,大环空临界携岩流量为12 L/s,小环空临界携岩流量为4 L/s。
在实际钻井工程中,环空中的钻井液流速不是处处相等,因为壁面的无滑移边界条件,靠近钻杆和井壁的钻井液流速较小,处于环空中心位置的钻井液流速较大。因此,导致靠近固体壁面的钻井液流速因达不到其对应的临界环空返速而影响了钻井液的携岩效率。
在此定义超过临界携岩流速的区域占总环空区域的比为0.8时所对应的环空流速为最佳携岩流速。则最佳携岩流量为临界携岩流量的R倍,定义其为最佳携岩系数,如式(42)所示。
Qopte=RQmin=RAVmin
当大小环空的临界携岩流量Qmin不变时,可以用R来表示不同的钻井液流量,得到R与有效携岩区域比之间的关系,结果如图8所示。
根据ZS102井的井身结构参数,对大小环空不同流量的携岩情况进行模拟,结果如表4所示。
根据图8表4,综合所有计算结果,无论大环空还是小环空,其最佳携岩系数均为1.4,则对于ZS102井,对于上部大尺寸环空的最佳携岩流量应为17 L/s,下部小尺寸环空的最佳携岩流量应为6 L/s。定义从压力剖面调节工具的分流量Qf与总流量Q的比值为分流系数q,即
q= Q f Q
因此,ZS102井的分流系数应设计为11/17。
在ZS102井喇叭口处(即大小环空交界处)安装分流工具,进行钻井液分流,具体情况如表5所示。
安装分流工具后,全井筒压力与温度分布与未安装前的全井筒压力与温度对比分别如图9图10所示。
图9可知,安装分流工具对井筒压力分布的影响很大,下部井段通过分流后,循环流量减小,循环摩阻减小,导致井底压力、循环压耗和泵压均降低。其中,井底压力从85.08 MPa降至80.30 MPa,降低约5 MPa,对防漏治漏有显著效果;而环空压耗从7.16 MPa降至2.40 MPa,泵压从20.97 MPa大幅降至7.22 MPa,降低约13 MPa,在满足携岩要求的前提下,使用分流工具可以起到显著节省泵压的效果。
相比之下,安装分流工具对井筒温度分布的影响较小。如图10所示,井底温度在安装前后分别为139.6 ℃与141.2 ℃,环空返出温度保持在34.0 ℃。虽然下部井段通过分流后,循环流量减小,摩阻生热量减小,但是钻井液携带热量的能力降低了,因此井底温度略有增加。
(1)综合考虑深井、超深井高温高压下钻井液的流变性和钻井液流量的改变,建立了基于分流工具的井筒流动数学模型。以ZS102井为例,验证了本文模型的准确性,与现场数据误差在10%以内。
(2)基于临界携岩理论,考虑了环空中钻井液流速的特性,提出了最佳携岩流量。以ZS102井为例,计算了最佳携岩流量,提出了ZS102井分流工具流量优化分配方案为:总循环排量17 L/s,向下分流量为6 L/s,从分流工具的分流量为11 L/s。
(3)在满足携岩要求的前提下,使用分流工具对全井筒温度影响不大,但可将井底压力从85.08 MPa降至80.30 MPa,将泵压从20.91 MPa大幅降至7.22 MPa,可起到防漏治漏、节省泵压的作用。
依据所建基于分流工具的井筒流动数学模型,可建立任意深井、超深井井筒流量分配优化方案。实现各种工况下流量分配方案的关键在于分流工具的结构设计与优化,这是分流工具未来研究的方向。
