龙门山北段泥盆系海口组砂岩储层特征
Characteristics of sandstone reservoir of Devonian in the north Longmenshan Mountains,China
摘要
Abstract
The reservoir characteristics of the Haikou sandstone of Middle Devonian Series in Jiangyou of Sichuan Basin are studied on the basis of measured sections and drilling core observations. Controlling factors of main reservoir space,mineral components,grain size,diagenesis and the diagenetic evolution models are analyzed by thin section observation,scanning electron microscope, porosity and permeability statistics and X-ray diffraction,etc.It indicates that the Haikou sandstone is a typical pore-type reservoir characterized by dominant primary pores,and can be considered as a typical reservoir model mainly composed of inter-granular pores.In the Haikou sandstone,the connection among the pores is good,with good positive correlation between the porosity and the permeability.The displacement pressure for the pores is low and the throat is large,reflecting a good framework of the pores.Therefore,the Haikou sandstone possesses favorable conditions for the accumulation of oil and gas.关键词
