Abstract:
Taking 14 coal in JMC1 well in Jixi basin Lishu Mining Area as the research object, by anlyzing the reservoir characteristics and their mutual relations, the reservoir characteristics are studied in order to propose development suggestions for 14 coal and coalbed methane. The results show that 14 coal in JMC1 well has the characteristics of complete coal structure, medium bed, higher gas content, high reservoir pressure, etc. Fracturing technology is available in the well because of the characteristics of the medium permeability and complete coal structure. It is suitable to carry out well-case perforating fracturing of 14 coal seam with the upper coal reservoir and separate pressure production with underlying 22 coal seam.
