四川盆地磨溪─龙女寺地区寒武系洗象池组地震地层学研究

利用地震波的振幅连续性和速度三个参数，在常规地震剖面和Ｇ－ＬＯＧ剖面上对磨溪─龙女寺地区寒武系洗象池地层进行微地震相的划分，结合测并、地质、微地震相和模型正演资料的综合分析，提出了该地区风化壳上含油气有利的微地震相及最有利的含油气地区。进-步充实了乐山─龙女寺古隆起下古生界风化壳地区的地震地层学研究。

A Seismically Stratigraphical Study of the Cambrian Xixangchi Group in Moxi-longnusi Area

By means of amplitude,continuous property and velocity of seismic wave,the authors in this paper try to classify microseismic facies of the Cambrian Xisangchi Group in MoxiLongnusi Area both in the conventional seismic section snd G-log section,Together with the comprehensive study of logging,geology,microseismic facies as well as forward modeling,they also analyse the most profitable microseismic facies of the weathering shell that may keep oil and gas in this area,thus reinforcing the seismically stratigraphical study of the weathering shell of lower Paleozoic group along Leshan-Longnusi Paleo-uplift.
