METHOD FOR REGULATING PRESSURE AT INLET TO FIELD DURING DEVELOPMENT OF MULTI-LAYER GAS FIELDS Russian patent published in 2022 - IPC E21B43/14 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry; it can be used in the development of hydrocarbon deposits. A method for regulating the pressure at an inlet to a field during the development of multi-layer gas fields includes the opening by wells of productive layers of a multi-layer field with different layer pressure and the production of hydrocarbons in two layers simultaneously by increasing a flow section of a wellhead adjustable angle fitting installed as part of a binding of wells of the layer with relatively high layer pressure. The change in the flow section of the wellhead adjustable angle fitting is carried out in automatic mode, using a remote-controlled industrial controller based on a microcontroller equipped with a radio module to control an electromechanical control drive and a position of a fitting needle. In this case, a power output of the controller is connected to an engine of the mentioned electromechanical drive, a shaft of which is connected to a pulley mounted on the fitting needle.

EFFECT: possibility to change the flow section of the wellhead adjustable angle fitting installed as part of the binding of layer wells with relatively high layer pressure in automatic mode.
