METHOD FOR CONDUCTING GAS-DYNAMIC STUDIES OF GAS AND GAS CONDENSATE WELLS Russian patent published in 2024 - IPC E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: method for conducting gas-dynamic studies of gas and gas condensate wells in the presence of a telemetry system in the wellhead connection and operation of wells without exceeding the maximum allowable specific content of mechanical impurities includes well development for a flare device and further well survey in three modes with gas release into atmosphere: with working flow rate of well, with flow rate of well established by process mode, and with maximum allowable flow rate of well. Content of liquid and mechanical impurities in the gas flow is monitored and stabilization of all measured parameters is monitored. If the content of mechanical impurities does not exceed the established limits, and there is no highly mineralized formation water in the well product, further investigation is carried out without gas releases into atmosphere provided that the well operates into the gas gathering network. At the same time in the process of execution of works there provided is long-term stabilization of thermobaric parameters in n modes and their fixation is performed. Well flow rate is controlled by flow meter assembly from well telemetry with control of pressure in cluster manifold.

EFFECT: increasing the efficiency of gas-dynamic studies of wells.
