| 摘 要： | 四川盆地南部官渡构造下沙溪庙组属致密砂岩储层,常规速度反演难以将有效储层从致密砂岩中分道辨出来,而孔隙度可以较好地将其区分.作者在测井曲线校正、测井孔隙度精细解释的基础上,结合扩展的地震体属性分析法和神经网络拟合法开展储层孔隙度预测,计算了下沙溪庙组孔隙度数据体,并以交互验证法作为质量控制手段,验证了结果的正确性.该数据体可以直观地反映出高孔隙砂岩的展布特征.在此基础上,根据下沙溪庙组储层地质特征,针对下沙溪庙组一砂组进行了孔隙度平面解释,描述了有效储层的平面展布特征,指出该地区下一步勘探的有利区域.

| Abstract: | The Jurassic Xiashaximiao Formation(J2s1) reservoir of the Guandu structure in South Sichuan is a compacted clastic rock reservoir.Its porosity can better discriminate the effective reservoir than the conventional velocity inversion does.Based on the well logs correction and detailed well porosity interpretation,this paper combines the extended seismic attribute analysis and the artificial neural network fitting method to predict the porosity,compute porosity data volume of J2s1,and demonstrate validity of ... |
