摘要
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。
Yongan14 of YA region lies in the south of Ya structure area. The drilled Y14 and Y14-1 wells in this area are not connected through analyzing the sand body, but it can not be distinguished effectively by post-stack impedance inversion. By petrophysical anal- ysis and pre-stack inversion, it reveals the rule of the sand horizontal distribution and ver- ifies the drilling situation of two wells.
