Theory and Practice on Non-Artificial Drainage of CBM High-Yielding Well

Abstract:

The principle of the non-artificial drainage of CBM wells is studied in this paper. Through theoretical research and engineering test analysis, it points out that to control casing pressure is the key means to realize the non-artificial drainage of CBM wells, and the physical model and mathematical model of the non-artificial drainage theory of CBM wells are established. The established theoretical model was validated in a group of horizontal well production in Jincheng mining area. The process of test practice showed that the horizontal well obtained the outstanding gas-yielding effects. The study results of this paper can provide the important technical support for CBM production wells to achieve high and stable yield, and have the greater application value.
