COMPARISON OF TECTONIC EVOLUTION OF OIL AND GAS TRAPS BETWEEN THE BACHU UPLIFT AND THE NORTH TARIM UPLIFT

摘要: 塔北隆起和巴楚断隆都经历过前缘隆起这一发展阶段,两者存在诸多共性。笔者通过对比塔北隆起和巴楚断隆中新生代构造发展的异同,认为巴楚断隆存在前缘隆起发育时间晚、破坏严重和距生油中心远等诸多劣势。但巴东斜坡区在后期演化上与塔北隆起更为相近,尤其是其周边背冲断裂带,具有后期构造变形弱、构造位置高、新老圈闭多、油源较丰富等优点,不失为下一步油气勘探重点地区。

Abstract: Both the North Tarim Uplift and the Bachu Uplift had gone through forebulge phase, so they had some similar features. By comparing their Mesozoic and Cenozoic tectonic evolution history, the authors consider Bachu Uplift has some shortcomings in collecting oil and gas: a little late of the forebulge development time, severe damage and too far away to the source of oil and gas. But Badong slope, especially the surrounding back thrust uplift zones, has some good merits such as lower post-tectonic stress, high tectonic position and many new and old traps. So Badong slope should be a focal zone in the next exploration process.
