摘要：

石炭系标准灰岩顶面的精细古构造演化分析结果表明,塔中45井-满西1井区块在古近纪沉积以前是一个大型古背斜构造发育区。尽管该构造在长期的继承发育过程中,高点虽有位移、形态也发生过变化,但基本上稳定存在。古近纪、特别是新近纪的新构造运动,彻底改造了该区的构造面貌,使其演变为北倾的大型鼻状构造的一个侧翼,新构造运动的发生调整了该区的油气运聚方向和成藏条件,在由翼部向构造顶部的油气运聚指向上,石炭系下部东河砂岩的上翘尖灭带和微-小幅度构造圈闭群,具有晚期成藏的石油地质特征,是新构造运动期间潜在的油气聚集带。

Abstract:

Detailed analysis of palaeostructural evolution of the marker on top of Carboniferous limestone shows that the Tazhong 45-Manxi 1block was a large palaeo anticlinal structure before the deposition of Paleogene. The structure was basically stable despite the facts that there were displacement of structural high and modification of structural features during its long succeeding development. The neotectonic movements in Paleogene,especially in Neogene, changed completely the structural appearance into one limb of a north-dippping large nose-like structure, resulting in different hydrocarbon migration direction and reservoiring conditions. In the area along the direction of hydrocarbon migration and accumulation from limb to crest of the structure, the updip pinchout zones of Donghe sandstone in the lower part of Carboniferous and groups of low to very low amplitude structural traps would be favourable to ate reservioring. They would,therefore, be the potential hydrocarbon accumulation zones.

Key words: Tarim basin, late reservoiring, Carboniferous, neotectonism
