摘要
本文提出的模型依据有机质成气体积急剧膨胀的特点，计算天然气运移过程中各时期的总生气量、烃源岩中的总残留气量，包括残余油溶解气量、残余水溶解气量及烃源岩本身的吸附气量，进而求得天然气的运移量并恢复运移史。避开了短时期内难以解决的机理性问题。在大民屯凹陷应用获得了成功。
According to the large expansion of the volume of organic gas generation, a model of gas migration is set up, by calculating the amount of gas generated and the amount of residual gasin source rocks (including solution-gas in residual oil and water, adsorbed gas in source rocks) at any geological time. This model makes geologists avoid many unsolved theoretical problems at present; moreover, it was used in the basin modeling of DMT sag successfully.
