摘　　要：在吸收消化国外先进模型基础上，以信息系统论思想确定了以油气运移聚集为核心的石油地质过程系统边界及主要事件；研制开发了沉积盆地油气运移聚集计算机模拟系统。该系统主要由４大部分构成：参数输入部分、模型主部件、中间数据链、成果输出部分，模型主部件包括原始厚度恢复模型、沉积压实、异常地层压力演化模型、成烃模型、油气运移聚集模型。系统在中国东部的渤海湾盆地、西部酒西盆地得到广泛应用检验，取得了满意的效果。Based on digesting and absorbing advanced models at home and abroad, the system boundary and main events of petroleum geologic processes were determined with theories of information system and the simulation system of hydrocarbon migration and accumulation in sedimentary basins was developed. This modeling system includes four parts, parameter input, main assemblies of modules, mid-data chain, result output. The dominant part of modules consists of restoring original thickness module, sediment compaction module, abnormally pressure evolution module, hydrocarbon generation module, and migration and accumulation module. T his system was applied to two typical basins of Jiuxi basin in Western China, and Bohai Bay basin in Eastern China. It has been demonstrated by practical data with high precision of simulation. Results show that models of system is effective. The system can be applied to any stage of an exploration basin or area, and can meet the requirement of input data for amount and mass.
