| 摘 要： | 由于储层岩性复杂、厚度小、岩性较细等诸多因素,致使乌南油田下油砂山组(N21)砂、泥岩波阻抗没有明显差异,某些井区分布范围相互重叠,甚至泥岩波阻抗高于砂岩波阻抗。利用特征曲线重构反演(自然电位)技术,使测井资料与地震反演结果有机地结合起来,可以较清晰地看出砂、泥岩的岩性界线,反演剖面的分辨率高于波阻抗剖面。

| Abstract: | Due to the complex lithology and thin deposition thickness,the wave impedance difference between the sandstone and mudstone is not obvious in N21 formation of Wunan Oilfield.In some regions,wellblock ranges are superimposition.Moreover,the wave impedance of mudstone is higher than that of sandstone.This paper uses the inversion of characteristics curve (SP) and combined logging data with seismic inversion,which improves the resolution.The resolution in inversion section is higher than that in wave impedance section. |
