摘要
为明确东胜气田锦120井区下石盒子组盒2+3段储层特征及勘探潜力,利用岩心、测井、试气及分析化验等多类资料展开研究。结果显示,盒2+3段岩性主要为长石岩屑砂岩、岩屑长石砂岩及岩屑砂岩。结果表明,锦120井区盒2+3段发育冲积平原辫状河沉积体系,主要微相包括辫状河道和心滩,砂体平均厚度20 m,呈南北向展布。根据岩性、物性及孔隙结构,可将储层划分为3类,其中I类占20%,属好储集层,为东胜气田锦120井区的高效开发提供了重要的地质依据。
To clarify the reservoir characteristics and exploration potential of the Box 2+3 members in the Jin 120 well area of the Dongsheng gas field,a study was conducted using various types of data including core samples,well logging,gas testing,and analytical tests.The results show that the lithology of the Box 2+3 members mainly consists of feldspar lithic sandstone,lithic feldspar sandstone,and lithic sandstone.The study indicates that the Box 2+3 members in the Jin 120 well area developed an alluvial plain braided river sedimentary system,with the main microfacies including braided channels and point bars.The average thickness of the sand bodies is 20 meters,and they are distributed in a north-south direction.Based on lithology,physical properties,and pore structure,the reservoir can be classified into three types,among which type I accounts for 20%and is considered a good reservoir.This provides important geological basis for the efficient development of the Jin 120 well area in the Dongsheng gas field.
