苏里格南区南部奥陶系马家沟组马五5段沉积微相研究

Study on microphase of 55 section of Ordovician Majiagou Formation in southern Surige District

利用钻井、测井等资料,结合测试数据,岩心的详细观察与描述资料,分析了研究区的主要沉积相带分布规律,认为研究区马五5段可划分为五种沉积亚相,并根据其岩性特征划分出5种岩性沉积微相组合,确定主要储集层段的沉积相带的分布,从而进行了有利区预测,对合理高效开发气田提供了依据。

This paper analyzes the distribution rules of the main sedimentary zone in the study area by combining the test data and the data of the study area can be divided into five sedimentary subphases,and divides five kinds of lidiological sedimentary microphase combinations according to the lithologic characteristics to determine the distribution of sedimentary zones in the main reservoir segments,which provides a basis for the reasonable and efficient development of gas fields.
