火成侵入

In my article , we first have made a conclusion by reservoir - forming chronology that the forming - age of reservoir is 108 . 27 ? . 57ma , of which , the source rock came from carboniferous - permian strata ; we have perfected our basin - modeling software , so it can calculate quantificationally the contribution radio to hydrocarbon - generating caused by igneous intrusion as a technical problem , in which we have a daring trail
本文首次在文安斜坡应用成藏年代学精确地测得了以石炭?二叠纪煤系为源岩的油气藏成藏年龄为108 . 274 1 . 57ma ；进一步完善了盆地模拟软件，首次定量地模拟计算了火成岩侵入对生烃的贡献这一技术难题，在这一方向上我们作了大胆的尝试。
