Gas cut degree evaluation method based on well opening overflow quantity

摘要: The invention discloses a gas cut degree evaluation method based on well opening overflow quantity. By means of killing parameters and the law gas-liquid two-phase flow in wellbore, quantitative relation description quantity shut-in casing pressure is achieved, calculation result can objectively reflect risk level degree. combining process, peak value other under situation that monitoring data provided mainly used for solving problem an existing state, cannot be effectively judged, defects prior art are overcome, cooperation with various on-site kick detection devices.
