In order to explore the damage characteristics of coal under different ultrasonic excitation time,the ultrasonic excitation test system,nuclear magnetic resonance imaging system,stereo microscope and automatic permeability test system of coal core were used to analyze the changes of pore structure,surface crack and permeability characteristics of coal under different ultrasonic excitation time. The results show that with the increase of ultrasonic excitation time,the change rates of T2 spectral peak area,total porosity,surface fracture area and permeability of small,medium and large pores in coal are linearly increased. When the coal body is excited by ultrasonic for 30 to 150 min,the change rate of T2 peak area of micro,medium and large pores increase from 14.60%,52.50% and 24.90% to 61.30%,145.50% and 235.70%,respectively. The total porosity change rate,surface crack area change rate and permeability change rate increased from 5.04 %,47.27 % and 41.67 % to 24.93 %,127.91 % and 208.33 %,respectively. Under the excitation of different ultrasonic time,the change rate of permeability of the coal and the change rate of total porosity and the change rate of surface cracking area are in line with the linear increasing relationship,with the increase of ultrasonic excitation time,the pore and crack modification effect of coal is enhanced,and the permeability can be improved.

为探究超声波激励作用下不同激励时长对煤体损伤的特性,利用超声波激励试验系统、核磁共振成像系统、体视显微镜、煤岩芯渗透率自动测试系统等,分析不同超声波激励时长下煤体孔隙结构、表面裂隙及渗透特性的变化特征。结果表明:随着超声波激励时长不断增加,煤体微小孔、中孔、大孔的T2谱峰面积变化率和总孔隙率变化率、表面裂隙面积变化率、渗透率变化率均呈线性增大关系;超声波激励煤体30~150 min,微小孔、中孔、大孔的T2谱峰面积变化率分别由14.60%、52.50%、24.90%增大至61.30%、145.50%、235.70%;总孔隙率变化率、表面裂隙面积变化率、渗透率变化率分别由5.04%、47.27%、41.67%增大至24.93%、127.91%、208.33%。在不同超声波时长激励下,煤体渗透率变化率与总孔隙率变化率、表面裂隙面积变化率均符合线性增大关系;随着超声波激励时长增加,煤体孔隙、裂隙改造效果提升,渗透率得以提高。

为探究超声波激励作用下不同激励时长对煤体损伤的特性,利用超声波激励试验系统、核磁共振成像系统、体视显微镜、煤岩芯渗透率自动测试系统等,分析不同超声波激励时长下煤体孔隙结构、表面裂隙及渗透特性的变化特征。结果表明:随着超声波激励时长不断增加,煤体微小孔、中孔、大孔的T2谱峰面积变化率和总孔隙率变化率、表面裂隙面积变化率、渗透率变化率均呈线性增大关系;超声波激励煤体30~150 min,微小孔、中孔、大孔的T2谱峰面积变化率分别由14.60%、52.50%、24.90%增大至61.30%、145.50%、235.70%;总孔隙率变化率、表面裂隙面积变化率、渗透率变化率分别由5.04%、47.27%、41.67%增大至24.93%、127.91%、208.33%。在不同超声波时长激励下,煤体渗透率变化率与总孔隙率变化率、表面裂隙面积变化率均符合线性增大关系;随着超声波激励时长增加,煤体孔隙、裂隙改造效果提升,渗透率得以提高。

In order to explore the damage characteristics of coal under different ultrasonic excitation time,the ultrasonic excitation test system,nuclear magnetic resonance imaging system,stereo microscope and automatic permeability test system of coal core were used to analyze the changes of pore structure,surface crack and permeability characteristics of coal under different ultrasonic excitation time. The results show that with the increase of ultrasonic excitation time,the change rates of T2 spectral peak area,total porosity,surface fracture area and permeability of small,medium and large pores in coal are linearly increased. When the coal body is excited by ultrasonic for 30 to 150 min,the change rate of T2 peak area of micro,medium and large pores increase from 14.60%,52.50% and 24.90% to 61.30%,145.50% and 235.70%,respectively. The total porosity change rate,surface crack area change rate and permeability change rate increased from 5.04 %,47.27 % and 41.67 % to 24.93 %,127.91 % and 208.33 %,respectively. Under the excitation of different ultrasonic time,the change rate of permeability of the coal and the change rate of total porosity and the change rate of surface cracking area are in line with the linear increasing relationship,with the increase of ultrasonic excitation time,the pore and crack modification effect of coal is enhanced,and the permeability can be improved.

煤炭是我国的主体能源和能源压舱石,高效抽采并利用煤中伴生的瓦斯,可杜绝矿井瓦斯事故、减少温室气体排放、改善能源供应结构、推动双碳目标实现[1],但是我国大多数的煤层渗透性较差,采用常规钻孔预抽瓦斯效率较低,需采用高效增透技术[2]。超声波增透技术作为一种具有广阔应用前景的无水增透措施,可通过施加超声波改造煤层孔裂隙结构及渗透特性,从而提高瓦斯抽采效果[3]
近年来,国内学者围绕超声波增透煤体进行了大量研究。鲜学福等[4]率先提出了可控声波处理煤岩体改善瓦斯渗透性的思想。康智鹏[5]、田洪波[6]、TANG Zongqing[7]等探究了超声波作用下煤体微观孔隙、裂隙结构演化特征,表明超声波可损伤煤体,增加孔隙孔径、数量,增大孔隙率,形成裂隙网。林海飞等[8]研究了脉冲超声波对煤体孔隙的影响机制,表明超声波可有效损伤煤体结构,改善孔隙分布。肖晓春[9]、赵鑫[10]等分析了超声波影响下煤体裂隙发育扩展特征,表明机械震碎作用可损伤煤体,贯通裂隙网络。于国卿[11]、马会腾[12]等研究了超声波功率、频率对煤体孔隙分布特征的影响,表明超声波可显著改善煤体孔裂隙结构,拓展瓦斯解吸通道。李树刚[13-14]、YANG Erhao[15]等发现增加超声波的功率可有效损伤煤基质,促使孔裂隙发育扩展,形成瓦斯运移网络,提高煤体渗透性。LIU Peng[16]、李业[17]等研究了不同超声波功率、时间下煤体孔裂隙与渗透率的变化特征,发现超声波功率、时间增加可提高煤体孔裂隙连通性,促进瓦斯解吸、扩散、渗流,并揭示了煤体损伤与瓦斯抽采机理。宋超等[18]探究了超声波激励对煤体微观结构的影响,揭示了机械振动可疏通封闭孔隙,形成次生裂隙,增大孔隙率,提高渗透率。姜永东等[19]分析了声场对煤层渗透性的影响特性,结果表明距声场越近,渗透率提高越显著。王昌伟等[20]研究了超声波激励时间下清洁压裂液改造煤岩的影响效果,表明超声波可改善煤体孔隙结构,提高渗透率,促进煤层瓦斯解吸。
综上可知:目前超声波增透煤体试验研究主要集中于功率、频率、煤阶等条件,实际上超声波增透煤体是能量累积损伤过程,其中,激励时长对煤体孔隙性及渗透性影响较大,还需进一步深入研究。鉴于此,笔者拟探究不同超声波激励时长作用对煤体孔隙结构及渗流特性的影响,通过设置不同激励时长,开展一系列超声波激励试验研究,对激励前后煤体孔隙度、表面裂隙宽度及渗透特性进行相关分析与讨论,以期揭示超声波激励下煤体损伤增透的时效性,为进一步深入研究超声波增透技术的适用性,指导煤层增透与瓦斯抽采工艺流程及现场应用提供理论依据。
煤样采自河南省焦煤赵固二矿二1煤层,为尽可能保证煤样原生结构与基本性能的同一性,降低非均质性对试验结果的影响,选取煤层同一位置原煤并密封运回实验室。利用煤样取芯机、切割机、磨平机将其制成Φ50 mm×100 mm圆柱型煤样,通过电子天平、游标卡尺、非金属波速检测仪等测量煤样质量、尺寸、波速,并筛选5个符合要求的煤样用于试验,煤样基本参数见表1
1) 超声波激励试验系统。该系统主要由超声波发生系统、换能器冷却系统、恒温水浴系统等组成[16]。超声波发生系统包括超声波发生器和超声波换能器。换能器冷却系统主要由空气压缩机和油水分离器组成,可通过持续过滤压缩空气为换能器冷却降温。恒温水浴系统包括低温冷却液循环泵和双层循环结构水浴槽反应釜,控制超声波激励煤体过程的水浴温度(-15~50 ℃,±0.5 ℃)。
2) 煤体孔隙结构测试设备。煤体孔隙结构测试设备采用核磁共振成像系统,磁场强度(0.3±0.05)A/m,主频率12.8 MHz,工作温度22~32 ℃,环境湿度30%~70%。
3) 煤体裂隙结构测试设备。煤体裂隙结构测试设备使用体视显微镜,放大倍率6.3~50 X,可选2~250 X,变倍比8∶1。
4) 煤岩芯渗透率自动测试系统。煤岩芯渗透率自动测试系统主要由应力加载系统、三轴压力室、渗流测试系统、温度控制系统、抽真空系统、数据采集处理系统等组成[15]。应力加载系统轴、围压0~10 MPa,精度±0.5 MPa,加载速率0~1 MPa/s;三轴压力室渗透压力0~15 MPa,精度±0.5 MPa;温度控制系统水浴温度20~100 ℃。煤体渗透率测试采用达西定律稳态法。
K g = 2 P 0 Q 0 μ L A ( P 1 2 - P 2 2 )
式中:Kg为煤岩渗透率,10-15 m2;Q0为气体流量,cm3/s;P0为大气压力,取0.1 MPa;L为煤岩高度,cm;A为试件横截面积,cm2;μ为气体动力黏度,MPa·s;P1为试件进气端气压,MPa;P2为试件出气端气压,P2=P0,MPa。
试验步骤如图1所示。
1) 将煤样置于40℃的恒温真空干燥箱中充分干燥至恒重(煤样质量变化不超过0.1%)。
2) 利用体视显微镜测定煤样表面裂隙面积。
3) 利用渗透率自动测试系统测定煤样渗透率(设定温度、轴压、围压、进气端压力分别为25 ℃、0.5、4.0、1.0 MPa)。
4) 将煤样置于真空压力为-0.1 MPa的真空加压饱水装置下抽气2 h,饱水至饱和,并在常温常压下利用核磁共振成像系统测定饱水煤样孔隙结构,然后置于岩石离心机中离心90 min,测定离心煤样孔隙结构,获取饱水与离心煤样横向弛豫时间T2谱图及孔隙率。
5) 对煤样真空加压饱水后,置于25 ℃恒温水浴箱中,将功率500 W、频率20 kHz的超声波探头垂直浸入液面20 mm,固定于煤样顶端上方30 mm处,并开展30、60、90、120 和150 min的超声波激励试验。
6) 重复步骤2)~4)获取不同超声波激励时长下煤样裂隙面积、渗透率、T2谱图、孔隙率等参数。
核磁共振成像系统通过测试孔隙含氢流体在外加磁场下横向弛豫时间绘制T2谱图,从而分析孔隙结构与流体分布信息变化特征[21]。横向弛豫时间T2与孔隙半径r关系可表示为:
1 T 2 = ρ S p V = F s ρ r
式中:T2为横向弛豫时间,ms;ρ为横向表面弛豫率,μm/ms;Sp为孔隙表面积,μm2;V为孔隙体积,μm3;r为孔隙半径,μm;Fs为几何形状因子。通常认为煤体孔隙多为圆柱形,ρ取0.05 μm/ms,Fs取2。
结合饱水—离心联测法[22]可知:
φ e = φ t · F F I B V I + F F I
φ r = φ t · B V I B V I + F F I
式中:φt为煤体总孔隙率,%;φe为煤体有效孔隙率,%;φr为煤体残余孔隙率,%;FFI(Free Fluid Index)为自由流体系数;BVI(Bulk Volume Index)为束缚流体系数;FFI+BVI为全部流体由饱水煤体T2谱面积分数计算得出。
为分析不同超声波激励时长下饱水态与离心态煤体孔隙结构变化情况,通过不同孔隙内水分子1H质子分布反演获取核磁共振测试数据,依据B.B.霍多特分类法[23],文中采用固定T2值(以1、10、100 ms为划分点)对煤体孔径进行划分,将孔分为微小孔、中孔和大孔,绘制不同超声波激励时长下煤体核磁共振T2谱图,如图2所示。
图2可知:经不同超声波时长激励后,饱水煤体T2谱各峰区间宽度与信号幅值较激励前均有所增加,离心煤体T2谱各峰区间宽度与信号幅值较激励前均有所减小,T2谱峰区间宽度增加表明孔隙孔径扩展,T2谱峰信号幅值升高表明孔隙数量增加,整体表现为超声波激励时长增加,饱水煤体T2谱峰面积增大,离心煤体T2谱峰面积减小。
通过T2谱图面积及其变化率(下式)可分析超声波激励时长对煤体孔隙结构的影响特征,如图3所示(T为超声波不同激励时长,min)。
Δ S = S i j - S 0 S 0 × 100 %
式中:ΔST2谱图面积变化率,%;S0为超声波激励前T2谱图面积;Sij为超声波激励后T2谱图面积;i为各孔隙;j为超声波激励时长,min。
图3可知:激励30~150 min时,微小孔、中孔、大孔的T2谱图面积变化量和变化率分别为95~432、310~611、255~2381和14.60%~61.30%、52.50%~145.50%、24.90%~235.70%,且各T2谱图面积变化率与激励时长均符合线性增长关系。这是由于超声波激励时长增加,超声空化、机械振动效应持续形成,煤体吸收能量不断累积,孔隙结构损伤发育,孔隙大小与数量逐渐增长。
孔隙率是表征煤体孔隙结构发育程度的重要指标,其大小直接影响着煤层渗透性。由于篇幅所限,为分析不同超声波激励时长下煤体孔隙率变化特征,仅绘制了超声波激励30和150 min前后煤体饱水态与离心态孔隙率分量和累积孔隙率,如图4所示。
图4可知:超声波激励时长增加时,饱水态煤体T2谱图宽度与孔隙率分量幅值及累积孔隙率较激励前均有所增大,离心态煤体T2谱图宽度与孔隙率分量幅值及累积孔隙率较激励前均有所减小,且自由流体空间占比增多、束缚流体空间占比减少。如激励150 min时,饱水态孔隙率分量第1峰T2最大宽度由4.076 ms增至5.486 ms、峰值由0.185%增至0.198%,第2峰T2最大宽度由66.855 ms增至69.345 ms、峰值由0.007%增至0.016%,第3峰T2最大宽度由336.680 ms增至375.616 ms、峰值由0.003%增至0.006%;饱水态累积孔隙率由3.37%增至4.21%;离心态累积孔隙率由2.86%减至2.20%。这是由于超声波激励时长增加,导致煤体进一步损伤破坏,微小孔隙逐渐转化为中大孔隙,更多封闭/半封闭孔隙打开串联,促使煤体孔隙连通程度逐渐增强。
为进一步探究超声波激励时长对煤体孔隙分布的影响特征,分析孔隙率变化量及变化率(式(6))与激励时长的关系,如图5图6所示。
φ = Φ 1 - Φ 0 Φ 0
式中:φ为孔隙率变化率,%;Φ0为超声波激励前孔隙率,%;Φ1为超声波激励后孔隙率,%。
图5图6可知:超声波激励时长增加时,煤体总孔隙率、有效孔隙率增大,残余孔隙率减小,且总孔隙率变化率、有效孔隙率变化率均与激励时长符合线性增长关系,残余孔隙率变化率与激励时长符合线性减小关系。如激励30~150 min时,总孔隙率变化率为5.04%~24.93%,有效孔隙率变化率为35.29%~294.12%,残余孔隙率变化率为-23.08%~-0.35%。这是由于超声波激励时长增加,煤体孔隙结构发育演化并相互联通,促使自由流体空间占比增多,束缚流体空间占比减少,总孔隙率增大。
煤体裂隙结构作为主要瓦斯运移通道,其变化直接影响煤体渗透性。为探究不同超声波激励时长下煤体表面裂隙演化特征,利用体视显微镜放大相同倍率观测煤体表面裂隙,并使用AxioVision软件分析煤体表面裂隙面积变化情况,如图7所示。
图7可知:激励前煤样表面裂隙较少、发育程度较小,激励后煤体表面裂隙宽度与长度扩展延伸,裂隙面积大幅提高,表明超声波激励时长增加时,煤体裂隙结构发育演化,表面裂隙面积增长扩大。如激励30 min后表面裂隙面积由0.55 mm2增至0.81 mm2,激励150 min后表面裂隙面积由0.43 mm2增至0.98 mm2
由于煤样表面裂隙存在初始差异性,无法通过绝对值变化探究超声波激励时长对煤体裂隙结构的影响特征,故采用表面裂隙面积变化率表征不同超声波激励时长下煤体表面裂隙演化程度,如图8所示。表面裂隙面积变化率计算过程如下:
V = S 1 - S 0 S 0 × 100 %
式中:V为表面裂隙面积变化率,%;S0为超声波激励前表面裂隙面积,mm2;S1为超声波激励后表面裂隙面积,mm2
图8可知:超声波激励时长增加,煤体表面裂隙面积增大,且其变化率与激励时长符合线性增长关系。如激励30 min后表面裂隙面积变化率为47.27%;激励150 min后表面裂隙面积变化率为127.91%,是激励30 min的2.71倍。这是由于超声波激励时长增加时,能量累积效应使煤体裂隙产生持续性演化影响,当累积能量大于煤体强度阈值时,煤体损伤破裂,原生裂隙拓展、次生裂隙发育,并相互贯通,形成丰富的裂隙网络空间。
渗透率变化情况可反映煤体孔隙性演化对渗透性改善的影响程度,故采用渗透率变化率可分析超声波激励时长对煤体渗透性的作用情况,如图9所示。渗透率变化率计算过程如下:
δ = K 1 - K 0 K 0 × 100 %
式中:δ为渗透率变化率,%;K0为超声波激励前渗透率,10-15m2;K1为超声波激励后渗透率,10-15m2
图9可知:随着超声波激励时长增加,煤体渗透率显著提高,且其变化率与激励时长符合线性增长关系。如激励30 min后,煤体渗透率由0.012 ×10-15 m2增至0.017 ×10-15 m2,变化率为41.67%;激励150 min后,煤体渗透率由0.012 ×10-15 m2增至0.037 ×10-15 m2,变化率为208.33%,是激励30 min的5.00倍。
不同时长超声波激励煤体前后,煤体损伤参数与渗透特性存在一定的相关性。为得出不同时长超声波激励前后煤体总孔隙率变化率、表面裂隙面积变化率与渗透率变化率之间的关系,以总孔隙率变化率、表面裂隙面积变化率为横轴,渗透率变化率为纵轴绘制煤体损伤参数与渗流特性关系如图10所示。
图10可知:不同超声波激励时长下,煤体渗透率变化率随总孔隙率变化率、表面裂隙面积变化率不断增长而递增,且均符合线性增长关系,采用拟合和回归分析相结合的方法,相关性均在0.974以上。超声波激励时长从30 min增至150 min时,总孔隙率变化率、表面裂隙面积变化率从5.04%、47.27%增至24.93%、127.91%,渗透率变化率从41.67%增至208.33%,超声波激励作用下,煤体总孔隙率、表面裂隙面积的增大有助于提高煤层渗透率。
煤作为双重孔隙的多孔介质,由于其内部存在水介质,当超声波在煤中传播时,容易产生空化效应、机械效应、热效应等现象。当部分声能转化为其他能量时,煤中水介质压强、密度等发生循环式波动,并在介质内部与界面形成空化气泡[24]。空化气泡凭借超声波辐射作用发生震荡、膨胀、收缩,并持续聚集吸收能量。随着超声波激励时长增加,空化气泡累积能量达到阈值时,气泡内部高温高压远大于空腔与水介质界面温度与压力,促使空化气泡溃灭,累积能量瞬间释放,局部温度、压力显著提高[25],导致煤基质持续受到冲击碰撞,不断产生疲劳损伤。同时,机械效应导致煤体发生撕裂破坏作用,促使薄弱处孔壁面不断破碎,煤基质颗粒逐渐剥离,内部孔隙发育演化,表面裂隙拓展延伸,并相互串联贯通形成孔裂隙网络空间[26]
1) 煤体在不同时长超声波激励作用下,煤体孔裂隙扩展,煤体总孔隙率变化率为5.04%~24.93%;表面裂隙面积变化量及变化率为0.26 ~0.55 mm2、47.27%~127.91%;随超声波激励时长增加,煤体T2谱图面积、总孔隙率、有效孔隙率、表面裂隙面积变化量及变化率均符合正线性关系,残余孔隙率变化量及变化率符合负线性关系。
2) 超声波激励30~150 min时,煤体渗透率变化量及变化率为0.005×10-15~0.025×10-15 m2、41.67%~208.33%,激励150 min的渗透率变化量及变化率是激励30 min的5.0倍;随超声波激励时长增加,煤体渗透率变化量及变化率符合正线性关系。
3) 不同超声波激励时长下,煤体渗透率变化率与总孔隙率变化率、表面裂隙面积变化率均符合线性增长关系,随超声波激励时长不断增加,促使煤体能量持续性累积,导致煤基质破碎断裂,孔裂隙扩展贯通,渗透率有效提高。
