叠前同时反演及定量解释在平湖油气田平西区块的应用
|
摘要
定量解释是基于岩石物理建模及定量解释模板的一种方法。它由井点处的钻井数据巧妙的将岩石物理与地震属性联系起来,并通过定量解释模板将它推广到不同孔隙度及油气水状态的适用范围,进一步利用地震属性(泊松比、纵波阻抗体等)外推岩石物理特征,从而达到刻画储层空间展布及含油气性预测的目的。将该方法应用于平湖油气田平西区块P8储层的含油气潜力预测,取得了良好的效果。
Based on rock physical property modeling and quantitative interpretation template,quantitative interpretation has been done for Pingxi Block,Pinghu Field.By using well data,the rock physical data and seismic attributes can be combined together for quantitative interpretation with quantitative interpretation template under the different conditions of porosity and different oil & gas and water status.Further,by extrapolation of the seismic attributes(Poisson ratio,P-wave impedance,etc.),the reservoir physical properties and hydrocarbon existence can be predicted.This method has been used in hydrocarbon potential prediction of P8 reservoir in Pingxi block,Pinghu field,and good results have been obtained.
