摘要
缝洞型碳酸盐岩油藏具有埋藏深、非均质性强、开发难度大等特点,国内对此类油藏的开发主要采用注水方式。矿场上根据缝洞之间的连通情况将储集体划分为单井缝洞单元和多井缝洞单元。本文分别对这两种缝洞单元在注水开发过程中需要考虑的开发原理、注水时机、选井原则等方面的内容进行了归纳和总结。对油田上采用注水方式开发此类型油藏具有指导意义。
The characteristics of fracturedvuggy reservoir are buried very deep, strong het erogeneity, difficult to develop, and so on. At present, the main method to develop this kind of reservoir is water injection. In the actual production, according to the connection between the fracture and vuggy, the reservoir is divided to two kinds,units of single well and units of muhiwell. In this paper, the main factors which should be considered are induced and sum marized. It contains development principle, the time of water injection, the principle of se lecting well, and so on. This paper is of a guiding significance to develop this kind of reser voir with the method of water injection in the process of practical production.
