摘要
塔里木盆地雅克拉断凸历经多期构造运动,成藏特征较为复杂。运用构造演化与成藏特点相结合的研究分析方法对该区油气勘探具有重要的指导意义。研究认为雅克拉地区主要经历了:加里东期缓慢隆升、海西期强烈隆升、印支-燕山期的继承发育阶段、喜马拉雅期前缘隆起四个阶段。经分析认为,大涝坝-丘里构造带新生界、雅克拉构造带西段、西北段的寒武系潜山具有良好的勘探潜力,同时预测雅克拉构造带西北段寒武系、奥陶系潜山下伏上震旦统也具有一定的勘探潜力。
The Yakela fractured salient of Tarim basin, reformed from multi- tectonic movement, is characteristic of more complex accumulation. The research and analysis method which combines with the tectonic evolution and accumulation features will guide the future oil and gas exploration in The Yakela fractured salient of Tarim basin. Studies points out that the Yakela region has four dominative movements, including Gary east period slow uplift, Hercynian orogeny strong uplift, Indosinian-Yanshan period-inherited development and the Himalayan periods front uplift. In this paper, author states that the Cainozoic of Dalaba-Qiuli tectonic group, the west section of Yakela tectonic group, northwest section of the Cambrian buialhill has good exploration potential, and forecasts Yakela tectonic northwest section of the Cambrian, Ordovician buialhill fell upper sinian group also has exploration potential. Yakela tectonic northwest section of the Cambrian, Ordovician buialhill fell upper sinian group was proposed as reserve selection in the future exploration.
