METHOD FOR GAS CONDENSATE INVESTIGATION OF WELLS Russian patent published in 2022 - IPC E21B47/10 

FIELD: gas condensate testing.

SUBSTANCE: invention relates to a method for gas condensate testing of wells. The method for gas condensate well surveys is used to determine the initial and current gas condensate characteristics of developed deposits. Wells of one well pad are grouped. Separate groups of wells include wells of one operational development object. In the first research mode, all wells of the group work in a research line. In subsequent research modes, the flow of the produced mixture of the wells of the group is alternately transferred to work in the gas-gathering reservoir. The wells of the group work into a gas gathering reservoir until the phase equilibrium in the reservoir system is stabilized. Then the wells are switched to a research line. The flow rate of each well is set using a control device. Conduct gas condensate studies of wells in each mode. Gas condensate studies are carried out until the accumulation in the separators of volumes of gas condensate and associated water sufficient to determine their flow rate and sampling. After completion of the studies in all modes, a system of equations for the material balance of gas condensate flows is compiled and solved. The gas condensate characteristics of each well of the group are calculated.

EFFECT: reducing the time of gas condensate studies.
