摘　　要：低渗透油藏通过压裂地层产生裂缝,进而达到改善油井井底流动条件、减缓生产矛盾、提高油层动用状况的目的。统计低渗透油藏压裂井累积增油、压裂前不稳定试井解释结果,分析有效渗透率、表皮系数、末点压力等参数与不同压裂方式累积增油之间的关系,以此增强对不稳定试井解释结果与压裂措施效果之间相关程度的再认识,为压裂设计的有效制定、压裂措施取得良好的增产效果提供数据支撑。low permeability reservoirs produce fractures by fracturing the formation,so as to improve the bottom hole flow conditions of oil wells,slow down the production contradiction and improve the production condition of oil reservoirs.Count the cumulative oil increase of fractured wells in low permeability reservoir and the interpretation results of unstable well test before fracturing,and analyze the relationship between the parameters such as effective permeability,skin coefficient and end point pressure and the cumulative oil increase of different fracturing methods,so as to enhance the re understanding of the correlation between the interpretation results of unstable well test and the effect of fracturing measures,and provide data support for the effective formulation of fracturing design and the good stimulation effect of fracturing measures.
