【摘要】 针对克拉玛依油田J230井区石炭系火山岩油藏水力压裂过程中人工造缝监测资料比较缺乏,不能很好评价压裂效果的问题,基于微地震监测技术的基本原理和方法,利用监测结果对压裂效果、裂缝产状、转向压裂等进行分析评价,并对分层压裂数据进行解释,同时结合井口压力监测,可获得闭合压力、液体滤失系数、液体效率以及裂缝宽度等成果。实现了对浅层石炭系火山岩油藏压裂开发效果的实时评价,为该类油藏措施方案的优选、注采单元的整体治理及提高采收率提供了参考依据。更多还原

【Abstract】 The monitoring data of artificial fractures during hydraulic fracturing in Well block J230 Carboniferous volcanic rock reservoir in Karamay Oilfield were limited,which could not effectively evaluate the fracturing results.Based on the basic principle of microseismic monitoring technique,the fracturing results,fracture occurrence and deflection fracturing were analyzed and the separate layer fracturing data were interpreted with the monitored results.Combined with wellhead pressure monitoring,the closure pressure,fluid loss coefficient,fluid efficiency and fracture width,etc.could be obtained.This technique allows for the real time evaluation of fracturing results for shallow Carboniferous volcanic rock reservoirs,providing bases for the optimal selection of stimulation measures,overall treatment of flooding units and improving recovery of similar reservoirs.更多还原
