关于吐哈盆地台北凹陷岩性油气藏勘探的几点思考
|
摘要
以吐哈盆地台北凹陷油气勘探形势为基础,结合对基本地质条件和成藏条件的特殊性分析认为:台北凹陷岩性油气藏勘探要以已知的构造背景为基础逐步展开,树立“富油气凹陷”满凹含油的理念,在全凹陷开展饱和勘探;加强低位体系域储集体的勘探;重视不整合面之上岩性圈闭的识别与描述;选择有利地区,努力提高地震资料的分辨率。同时指出了在台北凹陷侏罗系以上含油气系统开展岩性油气藏勘探的3类重要领域和相应区带。
Based on the analysis of oil-gas exploration situation of Taibei depression,and combined the analysis of basic and particular accumulation conditions,we conclude that the lithologic pools exploration of Taibei depression must be surrounding the pre-known structure zones and explorating the targets gradually,erect the concept that the Fuel-rich depression accumulates fuel in the whole depression,with saturate exploration to the whole depression;intensify the exploration of the reservoir of LST;pay attention to the identification and description of the lithologic traps above surface of unconformity and select the favorable zone to prompt the resolution of seismic effectively.At the same time,we point out three types of favorable exploration domains of Jurassic petroleum system and corresponding zones in Taibei depression.
