针对苏里格地区盒8段有效储层厚度薄, 横向变化快, 常规解释结果多解性强的特点,从测井、岩石物理分析入手, 开展叠前地震反演提取有效储层的弹性参数, 综合分析预测储层的含流体特性, 为钻探井位提供依据。实践证明该方法在苏里格气田苏14井区的井位优选中取得了很好的应用效果。

The effective reservoir in the eighth member of Shihezi Formation in Sulige area is characterized by thin thickness, rapid lateral variation. Based on logging and petrophysics analysis, the elastic parameters ( such as elastic impedance, Poisson’s ratio and so on) of the effective reservoir are obtained by prestack inversion, and fluid properties are analyzed, which can provide reference for drilling well location. Good result has been achieved in well location optimization in Sulige Gas Field.
