Embodiment Construction
[0035] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0036] Such as Figure 1-7 As shown, a device for heating coal reservoirs to increase the production rate of low-coal-rank coalbed methane includes a truck 1, a flow meter 2, a first gas booster 3, and a second gas booster arranged on the ground of the coal reservoir. Compressor 4, mixed gas separation device 5, methane storage tank 6, water collection tank 7, display screen 8 and control system, a U-shaped well and several production wells 9 are drilled into the coal reservoir on the ground, each Production wells 9 are distributed around U-shaped wells, and U-shaped wells and each production well 9 form a well pattern. U-shaped wells are composed of a first vertical well section 10, a horizontal well section 11 and a second vertical well section 12. The lower end of the first vertical well section 10 is connected to one end of the horizontal well secti...
