Abstract

The invention discloses a heating method special for coal bed gas thermal recovery comprises the following steps that firstly, the length of a coal bed to be subjected to thermal recovery is L, a ground control center, a generator and a ground wire winding vehicle are arranged on the ground above the coal bed, an intelligent cable winch is arranged on the ground wire winding vehicle, and a high-temperature-resistant tensile cable is wound around the intelligent cable winch; a first tension sensor is arranged at the wire outlet end of the intelligent cable winch; n hollow pipeline robot groupsare assembled, one end of the high-temperature-resistant tensile cable is connected with the generator, and the other end of the high-temperature-resistant tensile cable is connected with the rearmosthollow pipeline robot group; in conclusion, the device is high in automation degree, convenient to operate and good in pulverized coal removing effect, and the coalbed methane mining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of coal bed gas exploitation, and in particular relates to a special heating method for coal bed gas thermal recovery. Background technique [0002] Coalbed methane refers to the hydrocarbon gas stored in coal seams with methane as the main component, mainly adsorbed on the surface of coal matrix particles, and partially free in coal pores or dissolved in coal seam water. It is an associated mineral resource of coal and belongs to unconventional Natural gas is a clean, high-quality energy and chemical raw material that has risen internationally in the past ten or twenty years. Due to the generally low permeability of coal seams in my country, the methods and effects of gas drainage are greatly limited. Therefore, how to increase the permeability of coal seams to achieve the purpose of strengthening gas drainage is an important issue facing the coal industry. Experts at home and abroad have proposed some me...
