摘要
本次研究以成像测井资料为主、常规测井资料为辅,融合岩心地质分析资料,在精细的岩性和层理构造识别基础上,进行了以岩性相为单元的分类、物性研究。宁波油田X区块共发育7种岩性相单元,重点考虑储层物性和含气性等因素,认为在深层低孔渗基础上,粒度较粗、物性较好、层理构造发育、泥质胶结、电成像静态图像颜色呈暗色的岩性相为有利储层。
This study is mainly based on imaging logging data,supplemented by conventional logging data,combined with core geological analysis data,and based on the fine identification of lithology and bedding structure,the classification and physical properties of lithologic facies are studied. Seven lithologic facies units are developed in the target formation of block X in Ningbo oilfield. The factors such as reservoir physical properties and gas bearing properties are mainly considered. It is considered that on the basis of deep low porosity and permeability,the favorable reservoir is the rock facies with coarse particle size,good physical properties,developed bedding structure,argillaceous cementation and dark color in the static image of electrical imaging.
