Pore structure of deep coal of different ranks and its effect on coalbed methane adsorption
Yangtze University · Research Institute of Petroleum Exploration and Development
Abstract
To study the influence of coal metamorphism on the pore system development characteristics of deep coal reservoirs, coal samples of different ranks were collected as research objects. Based on maceral identification and industrial analysis, the pore structure of the coal samples of different ranks was characterized on multiple scales by combining low-pressure CO2 adsorption (L-PA), low-temperature N2 adsorption (L-TA) and high-pressure mercury intrusion porosimetry (MIP) experiments. In this paper, the distribution and variation in pores in coal samples of different ranks were investigated, the relationship between the pore structure characteristics and coal metamorphism was examined, and the influence of coal…
