Abstract

The invention relates to a sectional type oil pumping method. The method is characterized by comprising an electric generator, a surface pump connected with the electric generator, a power liquid tank connected with the surface pump, a high pressure control pipe connected with the surface pump, a wellhead device connected with the high pressure control pipe, an oil pumping unit connected with the wellhead device, an oil pumping rod connected with the oil pumping unit, a bolt support piston pump connected with the oil pumping rod, a connecting pipe connected with the bolt support piston pump, a hydraulic pump oil pipe connected with the connecting pipe, a hydraulic pump connected with the hydraulic pump oil pipe and a power liquid pipe connected with the hydraulic pump.

Description

technical field [0001] The invention relates to an oil extraction method in the field of oil extraction, in particular to a segmented oil extraction method. Background technique [0002] Existing oil recovery methods in oilfields mostly adopt rod pumps, hydraulic pumps and three mechanical extraction methods of hydraulic pumps. These three methods have their own advantages and disadvantages. Among them, the oil production depth of the rod pump is limited to about 5000 meters, the oil production depth of the hydraulic pump is limited to about 5000 meters, and the oil production depth of the hydraulic pump is limited to about 3000 meters. The oil extraction depth can only reach 5,000 meters, and there is no suitable oil extraction method for ultra-deep wells exceeding 5,000 meters. A segmented oil pumping method is proposed, which combines the rod pump and the rodless pump to form a multi-stage oil production device, and adopts a series connection method to exert the capabili...
