摘要
对DF气田储层孔隙度与地震属性之间的关系进行了分析 ,并对目前利用地震资料预测储层孔隙度方法进行了对比 ,在此基础上 ,选取多项地震属性与已钻井资料进行多维线性回归和随机地质统计相结合的方法 ,对DF气田储层孔隙度进行了横向预测。抽井检验结果表明 ,预测孔隙度与井点孔隙度吻合较好。
Based on analyzing the relationship between reservoir porosity and seismic attributes in DF gasfield and comparing the available methods to predict porosity by seismic data, an integrated method has been selected to predict lateral reservoir porosity in the field, which has combined the multidimensional linear regression of multiple seismic attributes and well data with the stochastic geological statistics. The spot checks indicated that the predicted porosity was quite in accord with the borehole porosity in DF gasfield.
