摘要
碳酸盐岩薄储层预测是油气勘探开发中的一个难点,鄂尔多斯盆地某勘探区马家沟组碳酸盐岩含气资源丰富,但储层厚度薄,工区地震资料品质相对较差,分辨率低,因此工区内的有利储层区域描述相对困难。为解决上述问题,采用了地震波形指示反演方法,与常规反演方法相比,克服了受井资料影响大、反演分辨率低等不足,提高了纵向分辨率,有效解决了苏里格马家沟组碳酸盐岩薄储层的预测问题。
The prediction of thin carbonate reservoirs is a difficult point in oil and gas exploration and development.Carbonate rocks in the Majiagou Formation in an exploration area in the Ordos Basin are rich in gas resources,but the thickness of the reservoir is thin,and the quality of seismic data in the work area is relatively poor.The rate is low,so it is relatively difficult to describe the favorable reservoir area in the work area.In order to solve the above problems,based on the characteristics of conventional inversion methods that are greatly affected by their own principles,well positions,number of wells,and low inversion resolution,the seismic waveform indicator inversion method is adopted,which improves the longitudinal resolution compared with conventional inversion methods.It effectively solves the problem of prediction of thin carbonate reservoirs in the Majiagou Formation in Sulige.
