东胜气田锦66井区盒2气藏储层四性关系研究

Four-property relationship of He 2 gas reservoirs in Jin 66 well block of Dongsheng gas field

运用岩心、录井、测井、试气试采及分析化验等资料,对东胜气田锦66井区盒2气藏储层岩性、物性、电性及含气性进行综合分析,建立相关关系,研究其内在联系。研究表明,东胜气田锦66井区盒2气藏储层岩性主要为长石岩屑砂岩、岩屑长石砂岩,属于低孔特低渗储层,含气性偏差;岩性控制着储层物性,储层含气性由物性、岩性共同控制;而储层电性关联着储层物性与含气性之间的相关关系,声波时差、电阻率及补偿密度能够很好地反映出储层的物性与含气性。

By using the data of core,logging,well logging,gas test,production test and analytical analysis,the lithology,physical properties,electrical property and gas bearing property of He 2 gas reservoirs in Jin 66 well block of Dongsheng gas field were comprehensively analyzed.The correlation among them was established and the internal relationship was studied.The study shows that the lithology of He 2 gas reservoirs in Jin 66 well block of Dongsheng gas field is mainly feldspathic lithic sandstone and lithic arkose sandstone,which belongs to the low porosity and low permeability reservoir and contains gas deviation.Lithology controls the physical properties of the reservoir,and the gas-bearing properties of the reservoir are controlled by both physical properties and lithology.The reservoir electrical property is related to the correlation between the reservoir physical property and gas bearing property,and the acoustic time difference,resistivity and compensation density can well reflect the reservoir physical properties and gas bearing property.
