ADAPTIVE CONTROL SYSTEM FOR PRODUCTIVITY OF GAS WELL PAD Russian patent published in 2015 - IPC E21B47/00 E21B43/00 

FIELD: oil and gas industry.

SUBSTANCE: system comprises PID-gas regulators coupled to wells and connected by their input to gas flow sensors and by their output to actuating mechanisms in the wells. To gas collection header of the well pad PID-controller is coupled by connection of its output through time quantiser to PID-gas regulators and by connection of its input through in-series impact filter and comparator between the preset value of gas pressure in the well pad and value of gas pressure in gas collection header of the well pad to a gas flow sensor mounted in gas collection header of the well pad. A remote automated station sending the productivity setting to the comparator is used as productivity setup unit.

EFFECT: ensuring stable coordinated control for wells in the pad, increasing accuracy and quality of transient processes for gas pressure regulation in gas collection header of the well pad, increasing endurance for actuating mechanisms of wells, increasing reliability and zero accident rate, reducing influence of human factor at gas field operation.
