摘　　要：根据统计分析,页岩油区块的漏失主要集中在八道湾砂岩段、梧桐沟和芦草沟组,同时也是井漏损失时间较多的层段。通过对地层孔隙特征、岩石成分以及地层压力进行评价与分析,开展了漏失机理研究,明确了井漏的核心因素并对症下药,通过优选与地层裂缝相匹配的堵漏材料,优化形成了适用于吉木萨尔致密油地层的油基钻井液防漏堵漏配方,通过现场2口井的堵漏实践,取得了良好的应用效果。According to statistical analysis,the loss of shale oil block is mainly concentrated in Badaowan sandstone member,Wutonggou and Lucaogou formation,and it is also the formation with more loss time.Based on the formation pore characteristics,rock composition and formation pressure evaluation and analysis,the paper carried out the research on the loss mechanism and identified the core factors of well loss.By optimizing the plugging material matching with the formation fracture,the oil-base drilling fluid plugging formula suitable for Jimsal tight oil formation is optimized and formed.Through the plugging practice of two Wells in the field,good application effect is achieved.
