白音查干凹陷三维地震资料整体连片技术及效果

3D Seismic Data Merged Processing Technology and the Effect in Baiyinchagan Sag

自1993年开始,中原油田根据不同时期、不同勘探目标,在白音查干凹陷总计采集了10块三维地震资料,区块总的特点是面积小、南北分片,不利于凹陷总体研究和下洼勘探,随着凹陷勘探的深入,"邮票"式资料的不足显露出来。为了适应该凹陷勘探开发的需要,对该地区的三维地震资料进行叠前时间偏移整体连片处理,消除不同时期采集资料品质上的差异,提高成像效果,使凹陷内所有资料成为一个有机的整体,为该区勘探突破打下了坚实的基础。

Aiming at different targets during developing period,Zhongyuan Oilfield has acquired 3D seismic data of small-scale for 10 disperse batches in Baiyinchagan depression since 1993,it was unfavorable for local research and depression exploration,stamp patterned data was not content with depression exploration development.In order to meet the requirement of exploration in the sag,Geophysical Research Institute of Zhongyuan Oilfield Company adopts the 3D data merged processing technique using 9 batches,which eliminates field data difference and lays solid foundation for exploration breakthrough.
