Pore Characteristics Research of Coal Reservoir in Fengfeng Mining Area
Fengfeng mining area is not only an important coal base in China,but also rich in coal bed gas resources.The porosity of coal reservoir under high pressure(12MPa)saturated water method is between 1.28%～5.73%.The total pore volume of BJH is 0.000 46～0.001 46mL/g,and the average pore size is 3.1～12.01nm.The types of pores are mainly micropores,small holes and mesopore three types,mainly micropores.The total specific surface area is 0.029 6～0.409m2/g.The more micropore is contained,the larger the specific surface is,the stronger the ability to adsorb coalbed methane,and the higher the content of coalbed methane generally.
