Abstract

The Songliao Basin, located in northeastern China, is rich in organic matter and develops organic shales deposited in continental environments. However, previous studies have mainly focused on marine shales, and there has been little research on terrestrial shales. The complex pore structure characteristics of shale reservoirs in the 1st member of Qingshankou in the Cologne Sag, Songliao Basin were studied by means of high-pressure mercury intrusion analysis and low-pressure nitrogen adsorption experiments. The results show that the transition pore is the most obvious in continental shale, followed by micro-pore, meso-pore and macro-pore. Transition pores contribute most to the volume and specific surface area of the pores. In addition, plate-shaped and flaky pores dominate, and connectivity is poor. This study is of great significance in understanding the pore structure of continental shale and the permeability mechanism of shale gas. The research results provide reference for the development, utilization and protection of the reservoir.
