METHOD FOR ADAPTIVE AUTOMATIC CONTROL OF GAS CONDENSATE WELLS Russian patent published in 2016 - IPC E21B43/12 

FIELD: oil and gas industry.

SUBSTANCE: invention can be used to control operating modes of gas producing well. Control of operating modes of gas producing well is formed on the basis of an adaptive pulse regulator acting on a time quantizer, in which there happens locking of control signal magnitude u_imi(t) during a given period (unit) of time with further action on the actuator mechanism controlling the regulating valve changing the amount of gas fed into the collector, ensuring quantized signal u_kv. At that, the adaptive regulator has control law where k_I, k_D are coefficients of integral and proportional components of PID regulation law, k_P(t) -common transmission coefficient, which varies according to equations: k_P(t)=k_H+γy(t), T_ay′(t)+y(t)=u_PIDa,kv(t), where filtration time T_a is calculated in standard units, and k_H>0 and γ>0 are adjustable parameters of the adaptive regulator.

EFFECT: increasing of resource of technical means of automatic elements.
