摘要

沙雅、卡塔克和巴楚隆起是塔里木盆地油气勘探的重点地区

截至2006年底提交的探明油气地质储量占整个盆地探明储量的66.78%

但3个隆起探明油气地质储量规模存在显著差异。有效供烃范围、优质储层的发育和空间展布、构造演化历史尤其是后期构造活动性的差异是导致3个隆起储量规模显著不同的主要原因。根据3个隆起油气成藏主控因素的对比分析

沙雅隆起油气成藏条件最好、卡塔克隆起次之、巴楚隆起相对较差。

Abstract

As the major exploration targets in the Tarim Basin

three uplifts

namely

the Shaya

the Katake and the Bachu Uplift

contained an accumulative proven geologic reserves which account for 66.78 % of the basin's total by the end of 2006.However

they varied greatly in the scale of their proven geologic reserves-a phenomenon caused by differences in effective source rocks

development and distribution of high-quality reservoirs

and tectonic evolution history(especially late tectonic activities).Comparative analysis on main factors controlling hydrocarbon accumulation in these uplifts revealed that the Shaya Uplift had the best condition for hydrocarbon accumulation

the Katake Uplift had a less favorable accumulation environment

and the Bachu Uplift had the worst.
