摘要： 油气成藏的物理模拟实验是在实验室条件下模拟油 气成藏的条件和结果,从而再现地下油气生成和运聚的过程。选取天然气运聚成藏这个重要过程,就川西平落坝天然气藏的成藏模式进行实验模拟,针对逆冲推覆断层对气藏形成的作用、对冲构造的成藏过程、原生气藏和次生气藏分别形成的过程等一系列重要问题得出很多认识:在平落坝原生气藏形成过程中,对冲构造起了重要作用,平落2逆冲断层对侏罗系次生气藏的形成起了重要作用,这些认识对川西前陆盆地天然气藏的下一步勘探有重要的指导意义。

Abstract: Hydrocarbon accumulation nodeling is to simulate the condition and result of oil gas accumulation under the given lab condilions, re-construct in-situ process o[ petroleum generation, migration and accumulation, by which a lab sinulation is nlade for Pingluoba gas accumula-tion pattemn in westerm Sichuan area. The effects of overthrust nappe faulting on gas pool fornation, petroleum accumulation in ranp structure and the ways for shaping primary and secondary gas pools are studied in this paper. Jt is concluded ihat the ramp sLructure plays an importanl part in the course of Pingluoba primary gas pool,and Pingluobas overthrust fault has the key effect for Jurassic secondary gas aceumulation. Above understandings could be as a guide for furtber exploration of natural gas pool in foreland basin of western Sicluan arca.

Key words: physical model, natural gas, oil-gas migration, oil-gas accumulation, pattern
