摘要
以南堡2-3区馆陶组为研究对象,开展沉积微相特征研究。南堡2-3区馆陶组时期为辫状河沉积,主要发育辫状水道和心滩沉积微相。对南堡2-3区馆陶组小层进行沉积微相平面展布特征研究,表明从NgⅢ12到NgⅠ3时期,心滩数量逐渐增多,砂体规模增加。该研究对寻找研究区优质储层有一定借鉴意义。
The Guantao formation of Nanpu 2-3 area as the research obj ect,to carry out the study of sedimentary microfa-cies characteristics.The Guantao formation of Nanpu 2-3 area is braided river deposit,which is mainly developed braided channel and diara sedimentary microfacies.The plane distribution characteristics of the sedimentary microfacies in the small lay-er of Guantao formation in Nanpu 2-3 area were studied,showed that from NgIII①2 to NgI3 period,diara quantity gradually increased,sand body scale increased.The research to find high quality reservoirs in this study area has a certain reference sig-nificance.
