Abstract: Based on detailed research on microstructure of mufti-layer faulted block reservoir,this paper suggests to divide microstructure into five different styles: ridgelike microstructure, comer microstructure, small bounded fault block, normal microstructure and reverse microstructure. The first four styles are regarded as favorable fairways of the remaining gas. It points out that techniques of mufti-targets directional well and horizontal well will be the effective way to explore the forming of remaining oil by different styles of microstructure.

Key words: fault block, reservoir, microstructure, remaining oil, multi-targets, directional well, horizontal well

摘要： 通过对多油层断块油藏的微构造进行研究,提出了断块油藏存在屋脊式、墙角式、封闭小断块式及正向、负向微构造5种类型,认为前4种类型是剩余油的有利富集区,指出地质多靶定向井和水平井技术是挖潜不同类型微构造形成的剩余油的高效方法.
