迈陈凹陷位于雷州半岛,是北部湾盆地的一个次级凹陷。该区勘探程度相对较低,钻井测井资料较少,加上地表与地下地质条件复杂,常规的波阻抗反演方法不能很好的解决该区的储层预测与描述,储层的识别与描述成为该区勘探的难点。针对这一问题,采用多曲线重构方法,由分辨率较高的目的层测井曲线重构出能够准确反映地层物性变化的声波、密度曲线,然后利用这些曲线进行稀疏脉冲波阻抗反演,该方法很好的解决了徐闻地区测井钻井资料少的问题,提高了反演剖面的纵向分辨率,从而更加精确的识别泥岩盖层和砂岩储层。预测出研究区的东南部地区是有利区,为进一步的井位勘探提供了有利目标。 Located in the Leizhou Peninsula, the Maichen Sag is a secondary depression in the Beibu Gulf Basin. This area has a relatively low level of exploration, less well logging data and complex surface and subsurface geological conditions. Conventional wave impedance inversion methods can not well solve the reservoir prediction and description, reservoir identification and Description has become a difficult exploration area. To solve this problem, the multi-curve reconstruction method is used to reconstruct the acoustic and density curves that can accurately reflect the change of physical properties of the formation from the well logging curves with high resolution. Then, the sparse pulse impedance inversion is performed by using these curves. The method well solves the problem of less well logging data in Xuwen area and improves the vertical resolution of the inversion section so that the mudstone caprock and sandstone reservoir can be more accurately identified. It is predicted that the southeastern part of the study area is a favorable area, which provides favorable targets for further well location exploration.
