地质统计学反演在什邡气田A区块储层预测中的应用
Application of geostatistical inversion to reservoir prediction in Shifang gas field
摘要
Abstract
Geostatistical inversion,an inversion method,has improved vertical resolution on the basis of wave impedance. It combines stochastic simulation with seismic inversion,constrained by seismic data,and then predicts the distribution law of reservoir by simulating reservoir's spatial distribution characteristics.The method is an effective tool for quantitative prediction. Taking a block of Shifang gas field as an example,to perform geostatistical inversion based on sparse spike inversion of wave impedance and get a set of high-resolution lithological inversion body from the integrating seismic data and well data with geo-logical data.According to comparison of the application for field data,it demonstrates that the prediction results coincide well with drilling,and prediction accuracy is improved obviously.In addition,the results of inversion provide a basis for subsequent calculation of gas reserves and production capacity building of development well.关键词
