Large model coal bed methane desorption and drainage device
1. Overview
Large model coal bed methane desorption and drainage device is based on similar principles to design experimental models of coal field sites in similar proportions, with the help of modern science and technology The latest achievements, such as computer technology, advanced sensor technology, etc., are carried out on the model to conduct physical simulation experimental research, thereby establishing a simulation experimental platform that simulates the step-by-step depressurization and precipitation mining method of coalbed methane under on-site formation conditions.
The main purpose of this device is to study the precipitation of coalbed methane and the distribution and changes of the pressure field during this process. It also studies the desorption process and rules of coalbed methane under different well pattern conditions using the staged pressure reduction mining method.
Using a large model coalbed methane desorption and drainage device experimental platform to study the spatial distribution of the pressure field during the coalbed methane desorption process, the pressure reduction speed, the coalbed methane desorption mechanism, etc., and control the changes in the production wells Bottom pressure and other data are used to optimize development parameters. Through the dynamic characteristics of coalbed methane production under different well pattern and well density conditions, the well pattern development plan is optimized.
