YA地区Y14块位于YA构造南部,该区钻探的Y14井与Y14-1井通过分析砂体不连通,但在叠后反演波阻抗剖面上不能有效分辨。通过岩石物理分析及其叠前反演,揭示了砂体的横向展布规律并验证了两口井的钻探情况。
The Y14 block in YA is located in the southern part of YA structure. The Y14 well and Y14-1 well drilled in this area are not connected to the sand body for analysis. However, the Y14 block can not be effectively distinguished from the post-stack inversion wave impedance profile. Through the petrophysical analysis and its prestack inversion, the horizontal distribution of sand body is revealed and the drilling of two wells is verified.
