摘要:

川南过渡带雷口坡组侵蚀面上存在数量较多的古残丘群,在沉积作用和差异压实作用下,可在古残丘斜坡地带形成香溪群储层的原始倾斜和尖灭,并可能产生同沉积期小断层和裂缝,有利于在上覆地层申形成运移、储集和圈闭空间,因此,可通过寻找雷口坡组侵蚀面上的古残丘来预测香溪群地层有利储集带,并得到了验证。

Abstract:

There are several paleo-hammocks on the erosional surface of Leikoupo Formation in the Central Sichuan-South Sichuan transitional belt.The Xiangqi reservoir may have been originally tilted and edged out as the result of the sedimentation and differential compaction,which may cause to develop small-scale faults and differential compaction fractures,and is helpful to form the space for travel,trap and reservoir in the overlaid beds.Therefore we can predict the existence of the promising reservoir belt in Xiangqi Group beds by looking for the Paleo-hammocks on the erosional surface of the LeikouPo Formation,which has been tested and verified.

Key words: Paleo-hammock, Seismic interpretation
