Abstract:

In order to reveal the microscopic pore characteristics and reservoir performance of high thermal evolution shale reservoir,according tothe tests of whole rock X-ray diffraction,organic carbon,helium porosity,nitrogen adsorption at low temperature,joint tests of high pressure mercury and adsorption,argon ion polishing,scanning electron microscopy and other tests,micro pore structure,type and their characteristics of high thermal evolution shale in the Lower Cambrian are studied.The results show that the specific surface area of shale is from 0.46m2/g to 34.70m2/g with an  average of 12.36m2/g,the total pore volumepergram shale is from 0.43×10-3cm3/g to 11.29×10-3cm3/g with an average of 4.65×10-3cm3/g,and the pore diameteris mainly small(2-10nm)and followed by medium(10-50nm).The relationship among total pore volumepergram,TOC and specific surface area is positive and linear.Shale developed 7 types of pores,i.e.,organic pore,intergranular pore,intragranular pore,clay interlayer pore,pyrite intergranular pore,structural micro fracture and diagenetic micro fracture.Micro cracks generally developed in all study area,organic pore,intergranular pore and clay interlayer pore mainly developed in Sichuan Basin,the pore outside Sichuan Basin mainly is organic pore,whose shape is irregular and narrow.Inorganic mineral poresundeveloped outside Sichuan Basin.It is believed that the difference of the pore type is closely related to the content of organic matter.

Key words: Shale reservoir, Pore structure, Pore type, Qiongzhusi Fomation, Lower Cambrian series, Upper Yangtze area
