盆地综合模拟系统BASIMS

BASIN INTEGRATED MODELING SYSTEM "BASIMS

油气盆地数值模拟是近十多年发展起来的新技术。它基于石油地质机理，应用多学科知识，定量模拟一个探区（盆地、坳陷、凹陷、次凹）的地史、热史、生烃史、排烃史和运移聚集史，从而进行综合评价，指出有利勘探地带。本文以我院研制成的盆地综合模拟系统ＢＡＳＩＭＳ为例，着重介绍地史、热史、生烃史、排烃史和运移聚集史这五大模型的最新方法以及油气资源综合评价技术。

The numerical simulation of oil/gas basin is a new technique developing for recent ten years. Based on the mechanism of petroleum geology and applying the multidiscipline, this technique can simulate an exploration area (such as basin,depression,sag and sub-sag)to get its geohistory, geothermal history, hydrocarbon generation history, hydrocarbon expulsion history and hydrocarbon migration-accumulation history,and then makes an integrated evaluation to indicate the favorable exploration areas.Taking the RIPED's BASIMS as a sample,this paper emphasizes the new methods for the five models of the histories mentioned above and the integrated evaluation technique.
