Coal Bed Methane Company Xinzhou Gas Production Management Area to Make People's Houses Warm and Prosperous
The Xinzhou Gas Production Management Area of CBM Company has fully implemented various production measures, and as of November 27, the daily gas supply has maintained a high level of 1.7 million cubic meters, and has fully guaranteed the heating of people's houses.
Since entering the winter supply, Xinzhou Gas Production Management Zone has accelerated the organization of production and operation, and intensified the measures of gas well production. Up to now, nearly 90 million cubic meters of gas have been supplied to downstream users.
Full release gas reservoir potential, productive gas. Aiming at the "four low" characteristics of low well pattern control, low reserve utilization, low desorption and low formation pressure utilization in Baode gas field, the management area carried out in-depth geological research, carried out gas content testing, well testing, digital core and other work to evaluate the remaining resources of each layer in the block. Continue to promote the description of fine gas reservoirs with the fine characterization of single coal seam as the core, carry out research on coal seam microstructure and subdivision of coal seam structure, and quantitatively characterize the distribution characteristics of gas field, hydrodynamic field, pressure field, desorption field, stress field, fracture network system field, etc. The implementation of the main coal seam patching fracturing, large-scale re-fracturing and non-main coal seam patching fracturing and other production measures, the degree of reserve utilization increased by 1.5%.
Improve the gas production capacity of a single well to produce enough gas. In view of the problems such as increasing decline of old Wells, less high-quality replacement reserves and less measures to tap potential in old areas, the management area innovatively implemented methanobacteria test research; In view of the relatively low production of gas Wells in the trench, measures such as upgrading production and discharge equipment and optimizing production and discharge technology are adopted to further increase the pressure reduction rate. Investigate low-producing Wells with upper production potential, and carry out upper production measures such as repeated fracturing and compensation fracturing to further improve gas well productivity. In Xinzhou Gas Production Management Zone, tests such as ultrasonic plugging removal, continuous machine washing and node pressurization have been actively carried out due to well policies, and a total of 594 Wells have been comprehensively treated, with a cumulative increase of 160 million cubic meters of natural gas.
