塔里木盆地东南隆起勘探潜力分析

Analysis for Exploration Potential of Southeast Uplift in Tarim Basin

塔里木盆地东南隆起勘探程度低,元古界基底上接受了晚古生代和中生代沉积,且分布范围局限,发育有侏罗系和石炭系两套烃源岩,目的层埋藏深,有四套可能的储盖组合,构造格局分为两凹两凸,资源量相对较小,勘探潜力不容乐观。

Exploration degree of southeast uplift in Tarim basin is low. Neo -paleozoic and Mesozonic deposition occur in Proterozoic basement with limited distribution range. There are two hydrocarbon source rocks developed in Jurassic and Carboniferous system, target zone deeply buried, there are four sets of reservoir - cap assemblages in the basin, the basic tectonic configuration is consisted of two sags and two uplifts, resources is relative small. Exploration potential of southeastern uplift is not optimism.
