大庆长垣西部地区油气运移动力学研究

建立在物理实验基础上的数字模拟技术正成为油气运移研究的重要手段。在对前人关于油气运移室内实验进行系统分析总结的基础上,以大庆长垣西部外围地区为例,运用盆地模拟方法恢复盆地演化过程,开展流体动力学研究。对大庆长垣西部外围地区各类输导体进行了定量表征,结合生、排烃研究成果,对油气运聚过程进行了模拟分析,并以黑帝庙油层为例阐述了油气运移路径及聚集范围,进一步指出了黑帝庙油层曾经遭受后期破坏作用。油气运聚模拟结果与实际地质情况比较符合。

Dynamic Research of Oil and Gas Migration in the Eastern Changyuan Region of Daqing Oilfield

Numerical simulation drawn from physical experiments became a main approach of the research of oil and gas migration. On the basis of systematical analyses of laboratory studies on oil migration performed by predecessors,the basin evolution process was recovered through basin modeling and a dynamic research was performed in western Daqing outskirts oilfields. Moreover, all sorts of transforming systems were quantitatively characterized. Simulation analysis was used for denoting the migration and accumulation of oil associated by research of hydrocarbon generation and expul-sion. Oil migration path and accumulation area of Heidimiao Reservoir were used for example. Therefore, it was pointed out that Heidimiao oil layer had ever damaged at the later stage. The result of simulation is consistent with that of actual geological situation.
