摘　　要：本文以安塞油田杏18-A为例,通过研究结果表明,较常规压裂而言,重复压裂工艺形成的裂缝体积增大了126.7%,平均单井日增油提高1.7倍,重复改造效果显著,可在安塞油田等致密砂岩油藏推广实施。This paper takes Xin 18-A block in Ansai oilfield as an example to make a research. The results show that,comparedwith the conventional fracturing,repeated fracturing process creates a larger crack volume that increases 126.7%,and the averagesingle well oil production increases 1.7 times. Repeated fracturing that has a significant effect can be implemented widely in tightsandstone oil reservoirs in Ansai oilfield and other similar reservoirs.
