OIL PRODUCTION METHOD Russian patent published in 1998 - IPC

FIELD: oil and gas production industry. SUBSTANCE: this relates to mechanized recovery of oil-gas mixture from wells. It cuts power consumption for recovery and compression of gas from annular space and for entire oil extraction, and also widens conditions for recovery and compression of gas by compressor with individual drive. According to method, compressor is connected with balance beam of rod-type pump on conditions of P_com< P_f a/c, where P_com - force created by compressor in compression of gas, N; P_f - force acting on head of balance beam at its downward movement, N; a - distance from point of support of balance beam to point of load application to head of balance beam at its upward movement, m; c - distance from compressor mounting point to balance beam support, m. Raising of liquid by pump takes place simultaneously with filling compressor cylinder with gas. Compression of gas by compressor takes place simultaneously with filling pump-compressor tubing with liquid above plunger. EFFECT: higher efficiency. 1 tbl, 4 dwg
