摘要/Abstract

摘要： 吐哈盆地台北凹陷西部是吐哈油田公司“九五”以来增储上产的主要区块,相继发现八个含油气构造带。通过对台北凹陷东西部侏罗系烃源岩的差异性分析,对台北凹陷西部原油进行了族群划分,认为台北西部原油可分成三个群组,分别对应以七克台组湖相泥岩为母源的“A”类原油,以水西沟群煤岩为母源的“C”类原油和以水西沟群煤系源岩复合成烃的“B”类原油。各类原油由于其母源成熟度和大量生排烃期的差异,导致其成藏期不同,以水西沟群煤系源岩为母源的油藏成藏期大都在晚燕山运动期,而以七克台组为母源的油藏其成藏期多在喜马拉雅运动期。

Abstract: As a target area of increasing reserves and production since “the ninth five-year plan”, in Taibei sag of Turpan-Hami basin operated by Turpan-Hami Oilfield Company,eight hydrocarbon bearing structural zones have been found one after another. This study analyzed the differences of Jurassic source rocks in west-eastern Taibei sag,and classified its crude oil group into three formations corresponding respectively to Type “A” crude originated from limnic shale in Qiketai formation, Type “C” crude from coal seam in Shuixigou group and Type B” crude (compound hydrocarbon) from Shuixigou coal measures as source rock. These types of hydrocarbons are of their different accumulation stages due to the differences in source rock maturity and in enormous generating/ expelling hydrocarbon stage. For Shuixigou group coal measure as source rocks, its hydrocarbon accumulation stage is mostly in late Yanshan tectonic movement, while for Qiketai formation as source rocks the stage mainly in Himalayan movement period.

Key words: Turpan-Hami basin, crude oil group, maceral, geochemical feature, petroleum accumulation stage
