准噶尔盆地腹部油气勘探程度较高,但不同年代、不同施工单位的地震资料存在着不同程度的闭合差。在腹部的连片编图中,利用Landmark解释系统,区分品质好、中、差的地震资料,分别设计校正流程,并依照用品质好的校正品质差的、用可靠的校正不可靠的、用三维校正二维的顺序对参与编图的地震剖面进行闭合差校正,为精细编图打下了坚实基础。 The degree of hydrocarbon exploration in the abdomen of Junggar Basin is high, but there are different degrees of closure difference in seismic data of different construction units in different years. In the contiguous posters of the abdomen, the Landmark interpretation system was used to distinguish the good, moderate and poor seismic data, and the correction procedures were designed respectively. According to the poor calibration quality with good quality, Three-dimensional correction of two-dimensional sequence of the seismic sections involved in compilation closed-end difference correction, laid a solid foundation for the fine mapping.
