一维盆地模拟系统BAS1

1-D BASIN MODELLING SYSTEM BAS1

一维盆地模拟系统 BAS1,已在微机、VAX 和 IBM 机上研制成功,并成功地应用于临清坳陷东部和泌阳凹陷的资源评价。BAS1系统是在既吸收国际上某些先进模型、又独创一些模型的基础上建成的,包括四个模型:地史,热史,生烃史,排烃史。输入资料主要来自于地质、测井、地震和地化。输出结果是盆地的沉积史、构造史、古热流史、古地温史、R。史、TTI 史、生烃史和排烃史。同时,三维盆地模拟系统 BAS3已在 IBM 和 VAX机上初步研制成功,即将投入应用。本文仅介绍 BAS1系统及其在临清坳陷东部和泌阳凹陷的应用效果。

1-Dimensional basin Modelling System BAS1 has been established on mic- rocomputer and VAX and IBM computers,and has been applied to resource estimation of the eastern Linqing depression and the Biyang sag successfully. BAS1 system is based on some advanced models published already and other advanced models written by ourselves,and consists of four models:Geohistory, Geothermal history,Hydrocarbon-generation history,and Kydrocarbon-expulsion history.Input data are mainly from geology,well logging,seismology and geochemistry.Output results are depositional history,structural history,paleo- -heatflow history,paleo-temperature history,Ro history,TTI history,hydrocar- bon-generation history,and hydrocarbon-expulsion history in the basin.3-Dimen- sional basin modelling system BAS 3 has also been established on IBM and VAX computer basically,and will be applied in the future.This paper presents BAS 1 system and its application in the eastern Linqing depression and the Biyang sag.
