随着油气勘探的深入,具有特殊运聚成藏机理的油气藏不断被发现,应用传统流体势研究油气运聚方向逐渐显露弊端.在综合分析以往流体势计算方法的基础上,据油气运聚机理,通过对研究区盖层底面形态、储层砂体展布和水压头的归一化处理,提出新的流体势计算方法.滨北地区的应用表明,该方法能更好地预测油气运移方向和路径,为油气勘探指明方向,且操作简单易行,参数容易获得,具很好的应用性.
With the deepening of oil and gas exploration, reservoirs with special mechanism of migration and accumulation are continuously discovered, and the disadvantages of gas migration and accumulation are revealed gradually with the application of the traditional fluid potential.On the basis of comprehensively analyzing the calculation methods of the fluid potential in the past, Mechanism, a new calculation method of fluid potential is proposed by means of normalizing the bottom morphology of the cover, reservoir sand distribution and hydraulic head, and the application in Binbei area shows that this method can better predict the oil and gas transport The direction and path of migration are the directions for the exploration of oil and gas, and the operation is simple and easy. The parameters are easy to obtain and have good applicability.
