摘　　要：三塘湖火山岩油藏岩性、储集结构复杂,物性、含油性和力学性质在分布上呈强非均质性,压裂改造面临高应力、高滤失、高缝内扭曲、难控缝等技术难题。依据该油藏开发压裂的资料,介绍了该油藏储集特征的研究成果和压裂技术机理;提出并实施了火山岩劈裂法和全程加砂法两种压裂方法,论述了火山岩压裂造缝三种施工模式。此压裂技术在该油藏应用效益显著,对国内同类油藏压裂改造具有借鉴作用。Lithology and structure of Santanghu volcanic reservoir are complicated,physical,oil-bearing and mechanical properties appear heterogeneously distributed,and so fracturing treatment meets technical difficulties such as high stress,high fluid loss and serious contortion in fractures etc.Based on fracturing practice during its development,the research results of characteristics of Santanghu volcanic reservoir and technical mechanics of fracturing treatment are introduced,two methods of fracturing,i.e.cleavage method and the method of sand-adding during the whole process,are proposed,and three operation modes of fracturing in volcanic reservoirs are discussed.This fracturing technique has been effectively applied in Santanghu reservoir,and will be helpful to fracturing treatment in other familiar reservoirs in China.
