塔里木盆地鸟山构造带构造演化时序及油气勘探意义

鸟山构造带位于塔里木盆地西南坳陷与巴楚隆起的分界部位，和田河气田区的西缘，是塔里木盆地内部重要的构造单元。本次研究结合钻井、地震等第一手资料，将鸟山构造带重新划分为3个次级构造：鸟山主体构造、鸟山东构造、鸟山北构造，并通过不整合面、平衡剖面等资料划分出8个构造演化阶段。鸟山主体构造与玛扎塔格构造原属一体，因差异应力作用而在发育撕裂断层（鸟山东断裂）之后两者分离，全新世晚期受晚喜马拉雅运动影响在鸟山、玛扎塔格、古董山之间发育右行走滑的鸟山北断裂。该构造带具有良好的石油地质条件，鸟山东构造带是该区最有潜力的区块，同时鸟山主体构造带也是该区比较有潜力的勘探区块。

Tectonic Evolution Series of the Niaoshan Structure Belt in the Bachu Uplift, Tarim Basin, and Its Significance in Hydrocarbon Exploration

Niaoshan structure belt,located at the junctional zone between the southwest Depression of Tarim Basin,and Bachu Uplift,and to the western margin of the Hetianhe gas field,is an important structure unit within the Tarim Basin.By using the drilling data and seismic profiles,the Niaoshan structure belt can be divided into three sub-structures: the main Niaoshan structure,the east Niaoshan structure,and the north Niaoshan structure.Eight tectonic evolution stages can be divided based on the unconformity data a...
