新木油田庙134区块沉积微相研究

Study on microfacies in miao134 block of Xinmu oilfield

依据研究区沉积环境,将研究区划分为分流河道、天然堤、溢岸砂、泛滥平原、水下分流河道、席状砂及分流间湾-湖相泥7种微相,分析了各微相沉积环境、岩性、沉积构造及电性特征,总结了沉积微相平面展布形态,将其分为单一条带状、窄条带状、交织条带状及宽条带状4种,这为后期细分注水奠定了基础。

On the basis of sedimentary environment of the study area,The study area is divided into 7microfacies including distributary channel,natural levee,overflow sand,flood plain,distributary channel,sheet sand and interdistributary bay-lacustrine mud.the sedimentary microfacies were analyzed from the aspects of sedimentary environment,lithological,sedimentary structure and electrical characteristics.The sedimentary microfacies distribution form contain 4types:single strip,narrow strip shape,weaving banded and wide banded.it provides the basis for the later subdivision water injection.
