Abstract
AbstractIn the process of natural gas production, formation water or condensate is usually produced along with it. The flow process of gas and liquid in wellbore becomes complicated, so it is very important to study the calculation method of bottom hole pressure with gas and water production in gas production process. At present, the pressure-drop prediction models of two-phase flow commonly used in engineering are mainly obtained by experimental methods based on different flow conditions. However, oil Wells mainly consider that the gas-liquid ratio of oil and gas Wells is generally much lower than that of gas Wells, and the prediction results are greatly different from the actual situation of gas Wells. Therefore, in order to simulate the wellbore flow state of a real gas well, establish a relatively ideal pressure drop prediction model of gas-water two-phase flow in a water well, and guide the design of drainage and gas recovery process, the author provides an experimental evaluation device and experimental method of gas-liquid two-phase flow for reference by scholars.KeywordsGas-liquid two-phase flowEvaluation deviceThe experimental method
