Abstract

The critical liquid-carrying flow rate is a core parameter for the dynamic regulation and reasonable production capacity assessment of gas Wells. The accuracy of its calculation formula directly affects the early warning of liquid accumulation in gas Wells, the optimization of production systems and the development benefits. The critical liquid-carrying flow calculation formulas widely used at home and abroad (such as Turner model, Min Li model, etc.) often have significant deviations from the on-site measured values under complex working conditions (high sulfur content, high pressure, low production, etc.) due to the failure to fully consider the flow state changes of gas-liquid two-phase, the coupling effect of fluid physical property parameters, and the actual structural differences of the wellbore. It is difficult to meet the precise development requirements. To enhance the applicability of the formula and the calculation accuracy, based on the theory of gas-liquid two-phase flow and combined with the on-site measured data of 325 production Wells in a certain gas field, this paper optimizes the critical liquid-carrying flow model.
