摘要

利用地震和钻井资料

结合前人认识

运用叠合盆地构造解析方法

分析了塔里木盆地巴楚-麦盖提地区早古生代古隆起的形成展布及后期构造演化过程

并从油气成藏条件的角度

阐述了其油气勘探意义。认为研究区在加里东中期-海西早期具备岩溶发育的古隆起背景

奥陶系岩溶储集体值得勘探重视;麦盖提斜坡北部与巴楚隆起南缘带在早古生代为古隆起的北斜坡区

是长期的油气运移指向区

利于油气聚集;麦盖提斜坡北部的海西晚期构造带

是下一步有利的勘探区带。

Abstract

Based on integration of seismic and drilling data and in combination with the previous studies

we analyze the development

distribution and later tectonic evolution of the Early Paleozoic paleouplift in the Bachu-Maigaiti area by using the structural analysis method of superimposed basin.Its significance for hydrocarbon exploration is presented from the perspective of hydrocarbon accumulation conditions.A paleouplift favorable for karstification existed in the Middle Caledonian-Early Hercynian in the study area

and thus attentions should be paid to exploration of the Ordovician karst reservoirs.The northern part of the Maigaiti slope and the southern margin of the Bachu uplift were the northern slope zone of the paleouplift in the Early Paleozoic.They are the long-term target zone for hydrocarbon migration

and also are favorable for hydrocarbon accumulation.The Late Hercynian structural belt in the northern part of the Maigaiti slope is favorable for further exploration.
