In view of the shallow burial depth, the high pore high seepage, the permeability, the low formation temperature (22-28 ℃), the thin reservoir thickness (2-6 m, averaging 3.5 m), the high underground crude oil viscosity (50000-90000 mPa·s),and the horizontal well thermal recovery,the horizontal steam flooding pilot test for the thin shallow super heavy oil of Chunfeng Oilfield is developed and carried out. The test area includes geological reserves of 102×104 t, 5 steam injection wells, 21 production wells. Both steam injection well and production well are horizontal wells, with the well spacing of 100 m, the distance between two rows of 140m, the horizontal section length of 200 m, the steam injection rate of 5 t/h, the production injection ratio of 1.2. 3 observation wells are drilled to monitor the real-time reservoir temperature and pressure. The pilot test lasted 19 months,and the steam flooding shows good performances with the indications as the single well daily oil production, the water cut, the periodical recovery percent of reserves, and with the recovery percent of OOIP being comparatively analyzed. In view of the heavy oil production declining, the steam flooding yields a production increase of 48% as compared with the steam soaking. The horizontal steam flooding pilot test for the thin shallow super heavy oil is confirmed to be feasible. With the pilot test,the conception of the high temperature micro- steam channeling production is formed, and the dynamic monitor and control system is established. together with a series technologies, including the horizontal well high temperature steam channeling management technology, the use of the horizontal well steam stimulation, the high deviated angle and the injection-production integration pump. Results provide some guidance toward the efficient development of the reservoirs., authors=ZHU Guilin, WANG Xuezhong, authorsList=ZHU Guilin, WANG Xuezhong, authorCompany=Xinchun Oil Production Plant,

口,对应21 口油井,注汽井、生产井均为水平井,井距100 m,排距140 m,水平段长度200m,注汽速度5 t/h,采注比1.2.钻打了3 口观察井,实时监控油层温度、压力.试验已历时19 个月,从单井日产油量、含水、阶段采出程度、地质储量采出程度等开发指标对比分析看,蒸汽驱见效明显.在考虑稠油递减规律的前提下,蒸汽驱比蒸汽吞吐产量增幅为48%.证实,薄浅层超稠油水平井蒸汽驱技术切实可行.试验过程中形成了"立足高温微汽窜采油"的开发理念和动态监控体系、水平井高温汽窜治理、水平井蒸汽吞吐引效、大斜度注采一体化泵等配套技术., authors=朱桂林, 王学忠,

    针对准噶尔盆地春风油田多轮次蒸汽吞吐后开发效果变差、亟需开发接替技术的难题,立足于春风油田埋藏浅、高孔高渗、地层平缓、温度低、储集层薄、地下原油黏度高、热采水平井整体开发的油藏条件,开展了水平井蒸汽驱先导试验.试验区动用地质储量102×104 t,部署注汽井5 口,对应21 口油井,注汽井、生产井均为水平井,井距100 m,排距140 m,水平段长度200m,注汽速度5 t/h,采注比1.2.钻打了3 口观察井,实时监控油层温度、压力.试验已历时19 个月,从单井日产油量、含水、阶段采出程度、地质储量采出程度等开发指标对比分析看,蒸汽驱见效明显.在考虑稠油递减规律的前提下,蒸汽驱比蒸汽吞吐产量增幅为48%.证实,薄浅层超稠油水平井蒸汽驱技术切实可行.试验过程中形成了"立足高温微汽窜采油"的开发理念和动态监控体系、水平井高温汽窜治理、水平井蒸汽吞吐引效、大斜度注采一体化泵等配套技术.

    The deterioration of the production performance after multi cycles of steam huff and puff necessitates the development of the supersede technology, in the Chunfeng Oilfield in Junggar Basin reservoir. In view of the shallow burial depth, the high pore high seepage, the permeability, the low formation temperature (22-28 ℃), the thin reservoir thickness (2-6 m, averaging 3.5 m), the high underground crude oil viscosity (50000-90000 mPa·s),and the horizontal well thermal recovery,the horizontal steam flooding pilot test for the thin shallow super heavy oil of Chunfeng Oilfield is developed and carried out. The test area includes geological reserves of 102×104 t, 5 steam injection wells, 21 production wells. Both steam injection well and production well are horizontal wells, with the well spacing of 100 m, the distance between two rows of 140m, the horizontal section length of 200 m, the steam injection rate of 5 t/h, the production injection ratio of 1.2. 3 observation wells are drilled to monitor the real-time reservoir temperature and pressure. The pilot test lasted 19 months,and the steam flooding shows good performances with the indications as the single well daily oil production, the water cut, the periodical recovery percent of reserves, and with the recovery percent of OOIP being comparatively analyzed. In view of the heavy oil production declining, the steam flooding yields a production increase of 48% as compared with the steam soaking. The horizontal steam flooding pilot test for the thin shallow super heavy oil is confirmed to be feasible. With the pilot test,the conception of the high temperature micro- steam channeling production is formed, and the dynamic monitor and control system is established. together with a series technologies, including the horizontal well high temperature steam channeling management technology, the use of the horizontal well steam stimulation, the high deviated angle and the injection-production integration pump. Results provide some guidance toward the efficient development of the reservoirs.
