摘要

针对钱家店凹陷九佛堂组储层低孔、低渗特征 ,应用钻井、测井、地震及化验分析等资料 ,对其储层的岩性、储集物性及储集空间特征等进行了研究。结果认为 ,钱家店凹陷九佛堂组储层的岩性为一套结构和成分成熟度均很低的陆源碎屑岩 (主要为中酸性喷出岩、变质岩岩屑 ,石英和长石 ) ;主要储集空间是粒间溶孔、粒内溶孔和微孔 ,储集物性为低孔、低渗 ;有利储层位于胡力海洼陷东四家子以北。这一结论为该区今后的勘探开发提供了地质依据。
According to its low porosity and low permeability features, litholoty, physical properties and spatial characteristics of Jiufotang formation, Qianjiadian sag were reviewed with the aid of drilling, logging, seismic, chemical experiment and the etc. Continental clastic rock with structures and components of rather low maturity, mainly comprising medium acid eruptive rock, metamorphic rock cuttings, quartz and feldspar, is the main lithology while prominent accumulation spaces are inter & inner-granular and micro-pores. Also, its low porosity and low permeability have all been necessary and essential for the future exploration and production of same area.
