METHOD FOR WORKING GAS LIFT FIELDS Russian patent published in 1995 - IPC

FIELD: gas wells. SUBSTANCE: method involves recording the current value of pressure change Δt_j in the hydraulic distribution system every time interval ΔP_j to the duration of this interval ΔP_j/t_j. Gas flow rate is measured on each well proportionally to the value , where A_i is the coefficient at the variable part of differential equation dQ_i/dV = A_iV+B_i, where Q is the yield, V is the discharge of gas, n is the number of wells. Changing values V_i are determined from formula ΔV_ik= L_iSign(ΔP/Δt)_k(ΔP/Δt)Dk

·G·S_k, where G, D are the coefficients depending on gas pipe-line network parameters, S_k is the coefficient showing the system reaction on changed gas supply when the well comes from the K-1-th to the K-th stage. The process lasts, until the relation (ΔP_j/Δt_j)_k= 0 is not valid. EFFECT: enhanced effectiveness of well in operation. 4 cl, 3 dwg
