摘要/Abstract

摘要： 油气藏形成是一个复杂的过程,具体可以划分为:前成藏期、成藏期和成藏期后3个阶段。前成藏期主要是圈闭形成期;成藏期是油气不断充注圈闭和圈闭定型期;成藏期后圈闭及其内部的油气可能受多种因素的影响而发生各种变化,从而改变油气藏的特征,甚至破坏油气藏。构造作用对油气藏的改造是十分明显的,可以将构造的改造作用划分为断裂作用、挤压作用和翘倾作用3大类。精细的构造分析和岩石学以及油气地球化学分析是研究构造作用对油气藏改造的重要手段。

Abstract: Petroleum reservoirs are generally formed in complex processes, which can be divided into pre-accumulation stage, syn- accumulation stage and post-accumulation stage. Pre-accumulation stage is a period of trap formation; syn-accumulation stage is hydrocarbon charging, entrapping and trap delineation period; post-accumulation trap and its hydrocarbons could be effected by various factors followed by resulting in a variety of changes or deformations, varying original characteristics of formed oil-gas reservoirs, even causing destruction of them. These significant tectonisms that could reform the reservoirs can be classified into faulting, compressive and tilting processes. The study shows that the integration of detailed structural analysis, lithology study and geochemical analysis of oil and gas is the essential tool for the study of tectonism on reconstruction of petroleum reservoirs.

Key words: petroleum reservoir, tectonism, faulting, trap, reconstruction, process
