Abstract

The invention discloses an immovable pumping unit which comprises an immovable vertical hoisting frame, a centering wheel, an oil outlet pipe assembly and a pumping barrel; wherein the bottom end of a vertical trapezoidal frame of the immovable vertical hoisting frame is vertically fixed on a square frame, a top guide wheel assembly is fixed at the top of the vertical trapezoidal frame, the vertical trapezoidal frame, a slanting pole and the square frame are fixed in a triangle shape, a steel wire rope of a winch bypasses the top guide wheel assembly and is used for lifting or lowering the pumping barrel; the steel wire rope is aligned to the center of the oil outlet pipe assembly through the centering wheel; a piston of the oil outlet pipe assembly is provided with a taper guide head and arranged at the bottom end of an oil outlet pipe, the oil outlet pipe is sheathed in the pumping barrel, the oil outlet pipe is communicated with an overflow pipe used for conveying oil; the oil outlet pipe assembly is fixed at a well head connecting device; an rope passing pipe is arranged in the oil outlet pipe; and the steel wire rope passes through a rope passing pipe and is connected with the body of the pumping barrel. The immovable pumping unit has the advantages that high-efficiency development with low energy consumption can be realized by equipment with simple structure, the development cost is lowered, and the labor capacity and the labor intensity are reduced.

Description

technical field [0001] The invention relates to an oil production equipment, in particular to a fixed oil scooping machine. Background technique [0002] At present, there are two main types of development for low-yield and marginal oil wells, one is the traditional rod-pump oil recovery, and the other is the fishing oil recovery. [0003] Rod pump oil production is to put the oil pipe and oil pump in the casing, and use the sucker rod to connect with the pumping unit on the ground to lift the piston of the oil pump to pump oil. The investment and maintenance costs of this oil pumping system are very high, even the cost is higher than the profit, and the safety is poor during maintenance. [0004] Fishing type oil production is mainly based on the chassis of the car, on which the hydraulic system is refitted and a winch is installed, and the telescopic derrick is the ground part, and the oil well pumping pump is lifted to lift the oil to the ground. In actual use, the lift...
