摘　　要：压裂改造体积(stimulated reservoir volume,SRV)计算是非常规油气藏压裂效果评价、生产动态预测等的关键环节。通过中外文献调研,梳理了SRV的概念、内涵以及目前主流的SRV计算方法,基于此总结了目前SRV计算方法在工业应用中的不适应性,并针对这些不适应性介绍了目前业界提出的SRV替代指标,即有效支撑体积(effective propped volume,EPV)和动态生产体积(active production volume,APV)。介绍了目前通过改进微地震监测手段确定EPV和APV的方法及其在现场中的应用效果,分析了方法现状和不足。同时,对解决目前SRV计算方法不适应性的问题提出了研究对策。Stimulated reservoir volume(SRV)calculation is of great significance for the fracturing effect evaluation and production forecast in unconventional reservoirs.Through literature research at home and abroad,the concept,content and main calculation methods of SRV were summarized.Based on this,the application inadaptability of current SRV calculation methods was summarized,and the alternative indicators,namely effective propped volume(EPV)and active production volume(APV)were proposed.Then,the calculation methods of EPV and SRV by modifying microseismic monitoring method were introduced.In addition,the application effect of SRV and EPV in oilfields was introduced,and shortcomings of these two indicators were analyzed.Finally,research suggestions for solving the inadaptability of current SRV calculation methods were proposed.
