摘　　要：为了准确评价东胜气田M井储层压裂改造效果,采用在压裂过程中加注微量元素,通过检测不同时段返排液中各种示踪剂的种类及含量,分析该井不同压裂段气、水产出能力与储层物性、压裂参数的关系,以此评价储层各压裂段改造效果,分析影响改造效果的主要原因。选取两相示踪剂对M井各段产出贡献占比实现有效测量,结果表明,各压裂段产气贡献与储层物性、含气性存在着一定的相关性,与压裂工艺参数的相关性并不明显,水平段钻遇的储层物性、含气性越好,产气贡献越大,产出越好。该研究成果为提升该区同类储层压裂改造的针对性和有效性提供技术支撑。In order to accurately evaluate the effect of reservoir fracturing in well M in Dongsheng gas field,trace elements were injected into the wells during the fracturing process.By detecting the types and concentrations of various tracers in the returned fluids at different time intervals,the relationship between gas and water production capacity in different fracturing stages of the well and reservoir properties,as well as fracturing parameters,was analyzed.This was done to evaluate the effect of reservoir fracturing in each stage and to analyze the main factors affecting the fracturing effect.The contribution of each interval in well M was effectively measured by using two-phase tracers.The results show that there is a certain correlation between gas production contribution and reservoir properties,gas content in each fracturing interval,whereas the correlation with fracturing process parameters is not significant.The better the reservoir properties and gas content encountered during horizontal drilling,the greater the gas production contribution and the better the production.The research results provide a technical support for improving the pertinence and effectiveness of fracturing stimulation in similar reservoirs in this area.
