摘要

吐-哈盆地含油气层系的地下水运动分为沉积水-渗入水和渗入水两个阶段。相应的油气有利聚集区分为:NW向的柯柯亚-丘东区带及胜金口区带;近EW向的南侧区;近EW向的北侧区带及盆地东西侧的局部地区。剖面二维有限元数值模拟揭示

断裂带在吐-哈盆地油气运移中起着重要作用

模拟的地下水排泄区与现有油田位置相一致。

Abstract

The motion of underground water in hydrocarbon bearing strata of Turpan Hami Basin could be divided into sedimentary seeping water stage and seeping water stage.Favourable areas for oil and fas accumulation are:1.NW directional Kokyar Qiudong and Sinjinkou zones;2.near EW directional south side zone;3.near EW directional north side zone and the local areas of the east and west sides of the basin.The numerical simulation of profile 2-D finite element reveals that fault zones play an important role in the basins oil and gas migration;simulated regions of underground water discharge coincide with that of present oil fields.
