摘要
盆地模拟软件系统有一维、二维和三维系统,模拟研究内容不仅涵盖了传统的“五史”——地史、热史、生烃史、排烃史和聚集史,还增加了许多非传统的研究内容。通过对技术现状的分析和总结,认为盆地模拟技术正朝着“系统化”和“工具化”的方向发展。新一轮全国油气资源评价的应用表明,盆地模拟技术在具体应用中不断发展完善并发挥越来越重要的作用:①促进基础地质参数研究的规范化,使资源评价参数更可靠;②解决有效烃源岩原始分布面积、排烃效率和裂解气计算等难题,使生烃量与排烃量的计算结果更准确;③结合多元统计技术的研究成果,更准确地预测油气资源量及其分布。
Basin modeling has developed for nearly 30 years. Up to now, basin modeling systems cover 1D, 2D and 3D model. They notonly include conventional 'five histories', i.e. geohistory, geothermal history, hydrocarbon generation history, expulsion history andaccumulation history, but also increase several unconventional studied contents. By analyzing and summarizing abundant related technologyinformation, it shows that basin modeling technology is developing forward to systematization and specialization. Through the applicationin the recent round national petroleum resource assessment of China, it was proved once again that basin modeling technology had beendeveloping and becoming more and more perfect, so it played an important role: Firstly, it promoted the standardization of base geologicalparameters so that they were more reliable; Secondly, it made the amount of hydrocarbon generation and expulsion be more accurate, throughrestoring the effective source rocks zone, introducing effective ratio of hydrocarbon expulsion, and by rectifying the amount of cracked gas;Finally, integrating results of statistical multianalysis, more accurately resource amount and its distribution were predicted.
