延长探区延153井古生界储层物性特征及主控因素研究

Physical Properties of and Controlling Factors for the Paleozoic Reservoirs in the Yan 153 Well in Yan’an Yanchang Exploration Area

延153井在石千峰组～马家沟组马五段(上部)进行了连续取心,对约50m的岩心及其近百块样品分析结果进行了综合研究,并对该井的储层微观特征及其主控因素进行了分析,为气田的下一步开发提供一定的指导。

This paper makes continuous coring （sampling）from the Shiqianfeng Formation to the No.5 Section of the Majiagou Formation through the Yan 153 Well, and makes comprehensive researches on the analysis results of more than 50 m cores and almost 100 pieces of samples, and analyzes the microscopic features and controlling factors of the reservoirs in this well, which provides the directions for the further development of gas field.
