摘要

随着四川盆地中北部地区长兴组、飞仙关组礁滩气藏的重大发现,川中地区已经成为四川盆地寻找大型岩性圈闭及岩性构造复合圈闭的主要区域。通过对新老地震资料的解释,结合地质、测井、钻井资料,研究了长兴组地震相,确定了川中地区长兴期地貌的变化情况,编制了川中上二叠统长兴组地震相展布图,确定了台内的蓬溪—武胜台凹,提出台凹两翼地貌高带是形成礁滩储层的有利区带。
Along with some important discoveries of Xujiahe Formation gas reservoir in Guang'an area and Changxing-Feixianguan formation bioreef-shoal gas reservoir in Longgang area,central Sichuan Basin becomes a very important region for finding out large-scale lithologic and lithologic-structural compound traps in Sichuan Basin.But,poor exploration on bioreef-shoal gas reservoir within platform may slow down a geological study on bioreef-shoal distribution and a seismic prediction.In this paper,some old and new seismic data from central Sichuan Basin are analyzed at first;and then,combined with some data from geology,well logging and drilling,the seismic facies of Changxing Formation is studied and the landform variation is determined;thirdly,the distribution map of seismic facies of Upper Permian Changxing Formation is classified;at last,the Pengxi-Wusheng Platform Depression is determined and a suggestion that the high of two limbs of depression is favorable to form bioreef-shoal reservoir is made.
