塔里木盆地巴楚隆起与塔北隆起构造-热演化的对比分析

摘要

Bachu uplift and Tabei uplift are located in analogous tectonic positions. We have recovered burialrnhistories, tectonic subsidence histories, and thermal histories of the two regions. The results indicate that therernare many unfavorable conditions for Bachu area to accumulate hydrocarbons, such as high basal heat flow,rnearly hydrocarbon generation, late paleouplift development, and severe activity of faults.%巴楚隆起和塔北隆起具有相似的的构造特征.从构造-热演化的角度出发,恢复了这2个地区沉积埋藏史、构造沉降史以及热演化史.通过对比分析,可以看出巴楚地区热流一直大于搭北地区,这可能导致巴楚地区生烃期早,而巴楚区隆起发育时间晚,后期断裂活动又比较剧烈,这些不利因素导致了巴楚地区勘探进展不如塔北地区理想.
