塔里木盆地乌什凹陷温宿凸起油气勘探前景
摘要
通过野外地质调查、岩性剖面与地震资料分析等方法,对塔里木盆地乌什凹陷温宿凸起的油气前景进行了研究。野外调查结果证实,乌什凹陷发育二叠系、三叠系、侏罗系3套烃源岩及多套储盖组合。烃源岩热演化史及地面油苗显示证实本区有油气运移聚集的条件和历史。地震资料显示喜马拉雅晚期运动导致与逆冲断层伴生的挤压构造十分发育,以挤压背斜为主体的构造构成油气聚集的有利场所。温宿凸起在地质历史时期曾与塔北隆起连为一体,是长期继承性发育的古凸起,古近纪卡拉玉尔滚大型走滑断层将其与塔北隆起分开。温宿凸起被乌什和阿瓦提两个已证实被具有生烃能力的生烃凹陷所挟持,是油气运移的指向区,同时存在碳酸盐岩和砂岩两类多个勘探目的层。乌什凹陷温宿凸起无疑是塔里木盆地油气勘探具有良好前景的战略接替区。
Oil and gas exploration prospect in Wushi sag and Wensu uplift of Tarim Basin was studied by the methods of geological investigation in the field and analysis of lithological sections and seismic information.The results of geologic investigation on the surface show that three series source rocks of Permian,Triassic,Jurassic and series of reservoir-caprock combinations developed in Wushi sag.The thermal evolution history of source rocks and the oil seeps proved that petroleum accumulation had happened in the area once.Compression anticlines formed during late Hymalaya tectonic movement were favorable site for petroleum accumulation in Wushi sag.Wensu uplift as part of Tabei uplift was an inheriting paleo-uplift during geologic epoch.It has been separated from Tabei uplift by the huge Kalayuergun fault since Paleocene epoch.Wensu uplift was hold by Wushi and Awati hydrocarbon-generating sag.There are poly exploratory horizons including two rock types of carbonates and sandstones at the same time.Therefore,Wushi sag and Wensu uplift are stratagem-superseding areas for oil and gas exploration with fine prospect in Tarim Basin.
