盆地模拟技术与BasinMod软件应用

盆地模拟是含油气盆地勘探评价的重要技术方法之一。BasinMod盆地模拟软件是用C++Builder4.0开发研制的微机版盆地模拟软件。应用BasinMod软件能够进行埋藏史、热史、生排烃史、油气运聚史的模拟和油气资源量估算。埋藏史模拟现已开通压实回剥法,热史模拟已开通地温梯度法,生排烃史模拟已开通烃产率法和化学动力学法,油气运聚史模拟已开通运载层吸附油气散失模型法,资源量估算已开通排聚系数法。BasinMod盆地模拟软件具有Windows图形用户界面,用户可以通过对话框进行软件操作,操作简单灵活,使用方便。

Basin modeling techniques and application of the BasinMod software

Basin modeling has long been employed as an important technique in the exploration and assessment of petroleum basins.The BasinMod2009 software developed by PRA Corporation in 2009 is introduced in the present paper to the modeling of burial history by means of backstripping compaction method,thermal history with the aid of geothermal gradients method,hydrocarbon generation on the basis of the methods of hydrocarbon production rates and chemical kinetics,hydrocarbon migration and accumulation according to the loss patterns of the absorbed oil and gas in the migratory beds,and estimation of oil and gas resources in the light of expulsion-accumulation coefficients method.It can be seen that the newly-developed software has many advantages of planar,sectional and three-dimensional modeling of various basins.
