Adaptability Analysis Of Coalbed Methane Drainage Process In Bowen Basin

On the basis of a large number of research,the characteristics,advantages and disadvantages and the adaptability of common mining equipment.The test wells in the Bowen Basin show poor results in the mining,the time of gas is generally late,the gas production is stable,The influence of geology(fault,permeability,coal seam thickness and depth)and drainage technology(drainage speed and drainage disturbance)on the drainage efficiency of Bowen basin was mainly analyzed.The selection of parameters such as pump type,pump speed and underground supporting tools resulted in the failure of a large number of pumps in the process of row mining,which seriously affected the efficient production of coalbed methane wells.Based on the actual data of the test wells in the Bowen Basin,the coalbed methane drainage equipment in the Bowen Basin is optimized by using the coal mine gas well drainage equipment optimization system,and the relevant parameters of the rod pump are optimized.Finally,The actual conditions of the mining equipment model,pump diameter,stroke,Chong times,etc.,through expert analysis,in line with the actual situation,which Bowen Basin coalbed methane well drainage provides a strong guarantee.which provide a strong effective protection to Bowen Basin.
