摘　　要：目前,水平井多段体积压裂是致密油开发的主要手段,为清晰水平井分段压裂的改造效果,预测生产趋势,吉木萨尔致密油水平井使用了微量元素示踪剂对水平段压裂进行监测。本文研究了示踪剂返排特征和压裂裂缝类型之间的关系,压裂主要形成微裂缝时,示踪剂返排曲线形态为正态峰型;压裂主要形成大裂缝时,示踪剂返排曲线形态为单缝型;当压裂形成的裂缝中大裂缝与微裂缝均有时,示踪剂返排曲线形态为单峰抛物线型。Currently the multi-section volume fracturing of horizontal wells becomes the main method for tight oil development. In order to analyze the effect of the muti-section volume fracturing technology and forecast production,trace element tracer is used in horizontal wells of tight oil in Jimsar Sag. Studies indicate the close relationship between the characteristics of tracer return and the types of fracturing fractures. it shows that when micro cracks dominate backflow tracer curve gives normal peak; large cracks tracer back row curve behaves as single slit type; and when large cracks and micro cracks coexist tracer back row curve show singlet parabolic type.
