Three Phase Flow Regulator

Abstract

The invention relates to the technical field of coalbed methane exploitation, in particular to a three-phase flow regulator, comprising: a gas proportional valve, a liquid proportional valve, a base, a solid addition unit, a mixing unit and an outlet plug. A first channel, a second channel, a third channel and an inner cavity are opened in the base. The gas proportional valve communicates with the inner cavity through the first channel; the liquid proportional valve communicates with the inner cavity through the second channel; the outlet plug communicates with the inner cavity through the third channel; the solid addition unit is connected with one end of the inner cavity, and the mixing unit is set In the inner cavity, gas, liquid and powder are mixed by the mixing unit and then output through the outlet plug. The three-phase flow regulator provided by the present invention inputs gas, liquid and solid respectively through the gas proportional valve, liquid proportional valve and liquid proportional valve, so as to facilitate the regulation of the flow or concentration of gas, liquid and solid in the three-phase flow, and realize the control of the three-phase flow regulator. Accurate control of three-phase flow parameters.

Description

technical field [0001] The invention relates to the technical field of coal bed gas exploitation, in particular to a three-phase flow regulator. Background technique [0002] Gas, liquid, and solid three-phase flow widely exists in coalbed methane extraction wells. In the initial stage of coalbed methane extraction, gas, liquid, and coal powder particles gather together in the extraction well, thus forming a gas-liquid-solid three-phase flow. The fluid parameters of three-phase flow are very important for evaluating gas production, coal seam working conditions, and predicting production trends. They are also important parameters for formulating drainage technology and predicting downhole accidents. Therefore, relevant scholars at home and abroad have conducted a lot of research on three-phase flow. Research. The basis for the study of three-phase flow is to establish a controllable three-phase flow model and precisely control the parameters of the three-phase flow, includin...
