王家岗地区沙二段成藏规律研究

Study on the accumulation rule of second section of shahejie formation in Wang Jiagang area

分流河道油藏是老区勘探开发过程中发现的一种新型油气藏类型。这种油藏具有隐蔽性强、成藏条件独特、分布广泛、富集高产、断层与河道匹配形式多样,因而研究难度非常大。文章在深入的地质研究基础上,从(沉积体系、成藏机理、配置关系、聚集规律)四方面对王家岗地区沙二段分流河道油藏进行了系统的研究,形成了一套油藏描述的技术方法,在实践中推广应用,取得了可喜的地质效果,经济和社会效益显著。

Distributary reservoir found in the exploration and development process the old area is a new type of oil-gas pool. This reservoir is hidden unique,widely dispersed,high-yield,and has a diversity match of faults and channel,so the research is hard to carry on.Based on a profound geological study,this paper researches on the second Quarter of distributary reservoir system in Wang Jiagang area from four aspects,a reservoir description technology is formed and is applied in practice.This study makes a gratifying effect on the geological,economic and social devvelopment.
