油气运聚过程的综合分析模拟

基于对油气运移机理现有认识的综合研究,提出了油气运聚模拟的地质概念模型和充分考虑地质综合研究并可人工干预的综合分析模拟.大尺度地质概念模型是以含油气系统为单位的三维面状模型,而小尺度模型则是以油气运聚单元为单位的、由一个或多个三维面以及断层组合而成的网络状格架模型.油气运聚过程的综合分析模拟应在层序地层格架内以含油气系统(或油气运聚单元)为单位建立初始地质模型,应用古构造恢复、古流体势恢复、油气运秽路径模拟、优势运移通道分析、模拟结果综合评价等技术,依据层序地层格架所提供的精确时间间隔单元进行三维的、动态的模拟.模拟的相关技术和方法可在信息集成平台的基础上,基于一系列空间数据处理方法开发实现.

Synthetic Analysis Simulation of Oil-Gas Migration and Accumulation

This paper puts forward the geologic concept model for simulation of oil-gas migration and accumulation based on existing mechanism integration,and method of synthetic analysis simulation taking into account the logic synthetic research and artificial interference.Large-scale geologic concept model is a 3-D surface model in which oil and gas system serves as a research unit,while the small one is a 3-D network model in which the migration and accumulation unit serves as a research unit,consisting of one or multiple 3-D surface and fault.The synthetic analysis simulation can be realized by using such technologies as ancient structure resume,ancient liquid force resume,migration pathway simulation,analysis of dominant migration route and synthetic evaluation of simulation result.The primary geologic model should be established in framework of sequence stratigraphy,where the oil and gas system(migration and accumulation unit) is taken as a research unit.Based on precise time interval unit from framework of sequence stratigraphy,a 3-D and dynamic simulation of oil-gas migration and accumulation can be realized.This method of simulation can be developed by using a series of space data processing technology based on platform of information integration.
