莺歌海盆地东方区中深层高温、高压储层特征及物性影响因素分析
Characteristics and Affecting Factors on Physical Properties of High Temperature and High Pressure Reservoir in the Mid-deep Formation of the Dongfang Area, Yinggehai Basin
摘要
Abstract
The in-depth analysis of characteristics and affecting factors on physical properties of high temperature and pressure reservoir has great significance for favorable reservoir and efficient development in the mid-deep Huangliu Formation of the Dongfang area,Yinggehai Basin.Based on the study of sedimentary facies,combined with the thin section analysis,grain size analysis,physical property and mercury penetration laboratory data,this paper presents a thorough analysis of the characteristics and affecting factors on physical properties of the reservoir in the study area,and the reasons for the differences of reservoir physical property of the same sedimentary facies in adjacent blocks.Analysis results show that reservoir physical property in the study area is fundamentally controlled by sedimentation,and that diagenesis is the major reason for the decrease of porosity.Although high temperature and high pressure promote the development of secondary pores,and protect the pores,but the permeability has not been effectively improved because of the complication of pore structure caused by dissolution.The main reason for the difference of reservoir property in the same sedimentary facies zone is that big throats are more developed in some local areas,where the fluid flows preferentially along the big pore throat,thus showing better permeability.关键词
