川东北须家河组储层特征及主控因素
Reservoir Characteristics and Main Controlling Factors of the Xujiahe Formation in Northeastern Sichuan Basin
摘要
Abstract
Exploration and research show that there has favorable exploration potential in Xujiahe Formation of northeastern Sichuan Basin, particularly in Yuanba shallow areas, and reservoir is the key factor for gas exploration. Reservoir is the key factor of gasfield distribution in Xujiahe formation of northeastern Sichuan Basin. Based on the study on petrologic, physical characteristics, pore types and diagenetic characteristics of the Xujiahe Formation sandstone reservoirs and their relationship, we conclude that sedimentary facies are the key factors to control the development of high quality reservoir. Diagenesis and tectonic fractures have an important impact on the development of sandstone reservoir, and the second stage of Xujiahe formation in the northeast of Yuanban area is the primary target for exploration where sandstone reservoir in the shallow of large-type of pores.关键词
