SYSTEM FOR COLLECTING AND TRANSPORTING PRODUCTS OF OIL WELLS Russian patent published in 2004 - IPC

FIELD: oil industry.

SUBSTANCE: system has a net of assembled pipelines (1) connected with wells (2) through a group of measuring devices (3), ejector (4), separating apparatus (5) and electric centrifugal motor (6) set in sump (14) which has pipe (15) provided with plug (16) at the bottom end and muffle arrangement (17) at the top end. The linear branch pipe (2) is in communication with the space of the pump-compressor pipes (18). Side branch pipe (23) is in communication with the interpipe space (22). Ejector (4) is interposed between net of collecting pipelines (1) and pressure pipeline (7). Assembled pipelines (1) are connected to branch pipe (8) for inflow of ejector (4) fluid. Linear branch pipe (20) is connected to nozzle (21) of ejector (4). Diffuser of ejector (4) is connected to the inlet of separation unit (5). Branch pipe (13) for water-oil products of separation device (5) is connected with the inlet of electric centrifugal pump (6) through side branch pipe (23) of sump (14) and interpipe space (22). Branch pipe (12) for gas-oil production is connected with the pressure pipeline (7).

EFFECT: decreased power consumption and enhanced environmental protection.
