摘    要:本文通过应用地层分析、构造体系分析和沉积体系分析的综合研究方法,对研究区内下第三系构造岩相带与油气聚集进行了研究。在阐述地层特征、构造体系类型与展布、火山岩岩相及沉积体系分布和演化基础上,总结出五种构造岩相带,指出构造岩相带是油气聚集的基本单元。各构造岩相带的油气藏类型及油气富集条件,取决于其中发育的圈闭因素与储集层的配置。

关 键 词:凹陷  石油  地质学  构造带  油气聚集

Abstract:Huimin depression is a subdepression in western Jiyang sag. This paper, based on geological, logging and seismic information, studies the tectonic-lithofacies belts and oil-gas accumulation of western Huimin depression and describes the stratigraphy features and the types and distribution of structural system. There are four kinds of faulting-structural systems, i.e. Neocathaysian structure, Chess-board structure, Brush structure and Eastwest structure systems. The structural systems control the distribution of volcanic rocks in time-space and poots related to volcanic rocks which constitute reservoir and cap of oil-gas and have no damaging effect, forming many kinds of traps. The types and features of serval kinds of depositional systems are described. The characteristics, distribution and evolution of five kinds of tectonic-lithofacies belts and the details of tectonic-lithofacies belts and oil-gas accumulation are given in the paper. The tectonic-lithofacies belt is the possible oil-gas accumulation belt, and various types of pools are generally governed by the assemblage of reservoir and trap.
Keywords:Depression  Petroleum  Geology  Tectonic zone  Oil-gas accumulation
