A new idea for lithologic trap description with little wells: Taking Liaodongwan area as an example
Online published: 2009-12-16
重力流成因的岩性油气藏是陆相断陷盆地高成熟阶段重要的勘探类型。少井地区岩性油气藏勘探的难点主要集中在区带优选、圈闭落实与圈闭描述3 个方面。研究者常对圈闭落实比较重视,而对区带优选和圈闭精细描述重视不够,这不利于岩性圈闭勘探的拓展和深入。鉴于此,以岩性圈闭为研究对象,提出“岩性圈闭表征”的概念,在对陆相断陷盆地重力流形成机制、发育模式与内部构成剖析的基础上,阐述了其在岩性圈闭区带优选、圈闭落实、圈闭描述及成藏分析中的应用,并论述了主要的研究思路和技术方法。实践证明,该概念的提出为岩性圈闭的勘探提供了一套有效的勘探思路和技术系列,对岩性油气藏的勘探将起到较好的推动作用。

Lithologic reservoir of gravity flow deposits are an important exploration target of fault-controlled lake basins. Exploration is difficult for the conversion of object, such as play choice, trap identification and description. Now petroleum geologists often pay attention to trap identification, but systemic study of formation mechanismand inner composition (specially not typical submarine fan deposits) are ignored. This paper first introduces the conception of lithologic trap description with the content of lithologic trap. It links geological dynamic analysis and geophysical static escription, and figures out the problemof play choice, trap identificationand description according to formation mechanism, development model and inner composition of fault-controlled lake basins. Then authors expound the main study methods and techniques. Exploration practice proves that the conception, method and technique are effective for lithologic trap and will promote the exploration of lithologic reservoirs.
