富黄槐树庄地区长6储层特征与主控因素分析

通过运用测井资料解释分析、岩石样品化验鉴定、扫描电镜观察等方法对研究区长6储集层的特征与主控因素进行分析,研究认为该区长6储层多为细小微细喉型及微孔隙喉型储层,岩石类型以粉-细粒或细-中粒长石石英砂岩及岩屑砂岩为主,具有较高的成分成熟度和结构成熟度,岩性主要是较高成熟度的内陆湖相砂岩；储集空间类型主要有残余粒间孔和粒间溶孔,该区微裂缝较发育,增加了油气储集空间；储集物性主要受沉积相和成岩作用控制,溶蚀作用和交代作用是改善储层的主要因素,而溶蚀作用的贡献最大.本次研究评价了富黄探区长6储层性质,为后期勘探提供了依据.

Characteristics and Controlling Factors of Chang6 Reservoir in the Huaishuzhuaung,Fuhuang Exploration Area

Characteristics and controlling factors of Chang6 reservoir in study region were investigated by logging data,core analysis,scanning electron microscope and other methods.The results show that main types of chang6 sandstone reservoir is small micro-throat type and pore-throat type,the sandstone type primary is powder-fines or fines-medium grained feldspathic quartz sandstone and lithic sandstone,maturity of composition and textural maturity are high,the lithology is high maturity inland lacustrine facies sandstone.Main types of reservoir space are residual intergranular pore and intergranular pore,micro-fracture is highly developed in this region,it has supplied some reservoir space,the reservoir physical property is controlled by sedimentary facies and diagenesis,denudation and replacement are main elements to improve reservoir,denudation’s contribution is largest.The paper can provide the foundation for later exploration stage.
