Underground Drainage With Gas Atomization Process Research

Papers for today's gas field, the actual needs of the drainage of gas, through the wellbore flow of gas-liquid two-phase mist flow pattern analysis, the work of atomizing nozzle theory and theoretical research, this paper presents application of spray nozzle method of drainage of gas will soon be Spray nozzles must be placed deep underground, using a good spray nozzle atomization of liquid gas in the gas-liquid two-phase flow effects on the liquid to spray through the spray so that the liquid into smaller droplets size, full the use of gas to carry the liquid gas-liquid two-phase along with the ability to give rise to surface wellhead to achieve the purpose of gas drainage. Articles by the working mechanism of various spray nozzle and gas production of the actual working conditions of the study, we use the pressure swirl atomizing nozzle as an atomizing device. Papers will be based on the production status of different wells or underground gas-liquid than the design pressure of the corresponding swirl atomizing nozzle, using simulation software, fluent in the underground work on the spray nozzle of the spray effect of the simulation, from the theoretical fog nozzle in the underground work of the feasibility of a fake pin verification, and design a set of spray nozzles packer downhole fishing tool and the nozzle into the hole of the process under the process. Finally the use of Visual Basic language developed to facilitate field use, according to well conditions quickly select the nozzle software. This paper has done research on the future of gas drainage technology research has important reference value.
