Application of Physical Modeling to Natural Gas Accumulation Analysis

Abstract

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
