川中-川西地区茅口组顶部地震相特征与成因
Characteristics and causes of seismic facies of Middle Permian Maokou Formation in central-western Sichuan Basin, China
摘要
Abstract
The characteristics of seismic facies data of Middle Permian Maokou Formation and its overlying strata are analyzed in order to solve such problems as lack of drilling data in western-central Sichuan Basin and the heterogeneous distribution of stratum resulted from the basalt eruption.Seismic identification reveals that the mainly seismic reflection on the top of Maokou Formation in Sichuan Basin is strong and has obvious weak amplitude clutter as well as contiguous distribution.The analyses of drilling data and sedimentary background show that the characteristics of seismic anomaly response of the top Maokou Formation in the south,middle and north sections of Sichuan Basin are resulted from different geological processes,such as volcanic eruption,volcanic sedimentation and carbonate karstfication.4 seismic facies zone in central-western Sichuan Basin are classified according to the differences of the overlying strata.It is considered that the Chengdu-Jianyang area likely to be a volcanic eruption zone during late Permian period because of the development of the basalt in this area,which is favorable for the evaluation of oil and gas.关键词
