Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0023] refer to Figure 1-4 , a hydraulic transmission reciprocating oil extraction pumping unit, comprising a base 1, the upper end of the base 1 is equipped with a support 2, the upper end of the support 2 is slidably provided with a steel wire rope 3, wherein the steel wire rope 3 is slidingly connected with the guide wheel at the upper end of the support 2, And when the wire rope 3 is stretched, it is easy to generate heat due to friction. The upper end of the base 1 is fixedly connected with a box body 4, and the top surface of the box body 4 is connected to the cooling mechanism. The air outlet end of the cooling mechanism is located above the support 2. The to...

Abstract

The invention relates to the technical field of petroleum extraction, in particular to a hydraulic transmission reciprocating type petroleum extraction pumping unit. By arranging a driving motor, an air suction mechanism and a cooling mechanism, effective cooling and heat dissipation can be carried out at the friction position of a steel wire rope and a bracket, cooling and heat dissipation can becarried out on the joint of the steel wire rope, a first fixed pulley and a second fixed pulley, so that the cooling and heat dissipation effect of the steel wire rope in use is effectively improved,the influence of friction heat production on the steel wire rope is reduced, and the using safety of the steel wire rope is ensured; and by arranging a lifting mechanism, the air suction mechanism, asecond transmission mechanism and a first transmission mechanism, the height of a hydraulic cylinder in a box can be adjusted, then the tail end height of the steel wire rope is adjusted, the heightof a pumping device fixedly connected with the tail end of the steel wire rope can be conveniently adjusted, then driving pumping is carried out on the pumping devices with different installation heights, and the using range of the pumping unit is enlarged and the convenience of the pumping unit is improved.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, in particular to a hydraulically driven reciprocating oil extraction pumping unit. Background technique [0002] Oil engineering is a general term for various engineering and technical measures taken to the reservoir through production wells and injection wells according to the development objectives in the process of oilfield exploitation. As a comprehensive applied discipline, it studies the theory, engineering design method and implementation technology of various engineering technical measures that can be economically and effectively applied to oil reservoirs to improve oil well production and crude oil recovery. [0003] When the hydraulically driven reciprocating oil extraction pumping unit in the prior art is in use, due to the friction between the wire rope and the guide wheel on the support, heat is generated during the friction process, and the friction point cannot be effectiv...
