Pipeline robot used for coal seam heating and pulverized coal removing

Abstract

The invention provides a pipeline robot used for coal seam heating and pulverized coal removing. The pipeline robot used for coal seam heating and pulverized coal removing comprises a ground wire winding vehicle, a generator, a ground control center and a plurality of groups of hollow pipeline robot sets, an intelligent cable winch is arranged on the ground wire winding vehicle, and a high-temperature-resistant tensile cable is wound on the intelligent cable winch; a plurality of groups of pipeline robots are connected through resistance wires. According to the pipeline robot used for coal seam heating and pulverized coal removing, the multiple groups of pipeline robots are connected through resistance wires, each group of pipeline robots form a relatively sealed space through forms of high-temperature-resistant air bags, electric valve sealing and the like, a high-temperature water-gas mixture generated by heating fracturing water flow by utilizing the resistance wires is pressed intoa coal seam, gas desorption is increased, the permeability of the coal seam is improved, reinforced extraction of the coal-bed methane is realized; and moreover, the multiple groups of pipeline robots have the function of removing pulverized coal, so that the gas production efficiency and the gas production rate of a coal-bed gas well are improved.

Description

technical field [0001] The invention belongs to the technical field of coal bed gas exploitation, and in particular relates to a pipeline robot used for coal seam heating and coal dust removal. 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 ...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned measures all need to shut down the gas production function regularly to remove the pulverized coal, which affects the process and efficiency of gas production. The above-mentioned measures can only be carried out outside the well, which consumes a lot of energy and cannot know the details of the well.
