摘要

塔北中、新生代油气藏的分布主要与古隆起、斜坡区和与之伴生的断裂和逆掩褶皱带有关。油气藏纵向上呈双层结构

形成3个聚集成藏模式:天山山前逆掩褶皱带模式、坳陷区模式和隆起区及斜坡带模式。勘探和地质条件分析表明

库车坳陷是本区唯一能发现大油气田的地区

雅克拉断凸-沙西北部、沙西凸起、阿克库勒凸起及隆起斜坡地区是寻找新的中小型油气田(藏)的有利地区。

Abstract

The distribution of Meso-Cenozoic oil (gas) pools in Northern Tarim is primarily related to paleo-uplifts

paleo-slopes and the associated faults and overthrust-fold zones. Vertically the reservoirs are composed of Meso-Cenozoic double-layer texture: horizentally they could be divided into Tianshan piedmont overthrust-fold zone

depressed zone and uplift (including slope) zone. Geological data analysis indicates that Kuqa Depression is the only place to discover large oil fields in the study area: Yakela faulted uplift-northwest Shaya uplift

west Shaya uplift

Akqule uplift and the slope areas are favourable for seeking mid to small size of oil and gas fields.
