METHOD FOR ADJUSTING THE OPERATING MODES OF MULTIPLE GAS AND GAS CONDENSATE BOREHOLES Russian patent published in 2023 - IPC E21B43/12 

FIELD: gas industry.

SUBSTANCE: invention relates to methods for producing gas from drilling boreholes. To implement the method for adjusting the operating modes of multiple gas and gas condensate boreholes, first, target values of equivalent diameters of the flow sections of the wellhead regulators are predetermined using a hardware-software hydrodynamic model of the cluster for each borehole in the cluster and the regulator at the entrance to the central gas treatment plant at the gas pressures, flow rates, and temperatures corresponding to the maximum production of hydrocarbons from the boreholes. The actual equivalent diameters of the flow sections of the wellhead regulators are determined for each borehole in the cluster at the actual layer and wellhead gas pressures, flow rates, and temperatures at the boreholes in the cluster and at the actual pressure before the regulator at the entrance to the central gas treatment plant. The target value of gas pressure before the regulator at the entrance to the central gas treatment plant is determined at the target value of equivalent diameter of the regulator at the entrance to the central gas treatment plant. The target flow rates and wellhead pressures are calculated for the first borehole in the cluster using the hardware and software model of the cluster, wherein the equivalent diameter of the wellhead regulator is substituted with the target value thereof. The calculation is repeated stepwise for the remaining boreholes in the cluster, substituting the equivalent diameter of the wellhead regulator of the borehole with the target value thereof at each step. The diameters of the remaining wellhead regulators are set according to the values thereof established at the previous step of calculation. The resulting pressure values are used when setting the target pressure value before the regulator at the entrance to the central gas treatment plant and then at the wellhead regulators of each borehole in the cluster.

EFFECT: control of the operation of multiple boreholes in a single cycle with an increase in the gas production.
