油势场的研究与应用

Study of fluid potential field and its application

讨论了用流体势场预测油气运移、聚集的方法.根据油势场对油气流动方向的控制作用及对油气富集与成藏过程的决定作用,确定了油势场分割槽与油气运移的基本关系,并对歧口凹陷石油资源的聚集与成藏规律进行了研究.研究结果表明:沙三段、沙二段以及沙一段下部均存在3个继承性油气汇聚流指向区,以及沙一段上部的3个高势区间的2个低势鞍部地带,都是油气运聚的有利地区,这是深入进行油气勘探时应特别重视的地区.

The control effect of fluid potential field on the migration and accumulation of oil and gas in Qikou depression is studied. It is held that three inherited hydrocarbon convergent zones in the lower of Sha1 member, Sha2 member and Sha3 member, and two low potential saddle zones in three high potential districts in the upper of Sha1 member are all favorable areas for the accumulation of oil and gas, and these zones should be paid attention to in the further exploration of Qikou depression.
