目前国内外利用地震资料进行储层预测时,采用的方法较多,但均存在一定问题(如反演分辨率低、多井外推及井间不闭合等)。针对Q三维地震工区目的层砂体薄、横向变化快的特点,在Strata软件上相继采用了三维波阻抗反演、测井参数反演和多属性伽马反演3种反演方法进行试验,最终确定了多属性伽马反演方法能较好地解决利用地震资料进行储层预测的一些问题,从而为工区勘探开发提供了可靠的高精度反演资料。
At present, there are many methods used for seismic prediction of reservoirs at home and abroad, but there are some problems (such as low inversion resolution, multi-well extrapolation and inter-well non-closure). According to the characteristics of thin sandstone and rapid lateral variation in the target sandstone in the Q 3D seismic work area, three inversion methods of three-dimensional wave impedance inversion, logging parameter inversion and multi-attribute gamma inversion were successively applied to Strata software. The multi-attribute gamma inversion method is finally determined to be able to solve some problems of reservoir prediction by using seismic data, thus providing reliable high-precision inversion data for exploration and development in the work area.
