Description

Combined energy-saving pumping unit

technical field

The utility model relates to an oil pumping unit, which is mainly a combined energy-saving oil pumping unit and belongs to the field of oil exploitation equipment.

Background technique

Pumping unit is an important equipment for oil exploitation, and it has a large number, wide application and high energy consumption. The total number of pumping units in my country is more than 100,000, and the annual power consumption exceeds 10 billion kWh, and its power consumption accounts for about 40% of the total power consumption of petroleum industry enterprises. At present, the most widely used pumping unit is the traditional beam pumping unit (commonly known as kowtow pumping unit). Because it needs to overcome the gravity to do work, it has the disadvantages of low operating efficiency and large waste of electric energy. For oil companies, saving power consumption can directly reduce the cost of oil extraction, so an energy-saving combined pumping unit is proposed.

Contents of the invention

The purpose of the utility model is to provide a combined energy-saving pumping unit.

The problem to be solved by the utility model is that the operating efficiency of the existing beam pumping unit is low and the waste of electric energy is large.

For realizing the purpose of the utility model, the technical scheme that the utility model adopts is:

The combined energy-saving pumping unit includes an oil well, a sucker rod, a rope, a fixed pulley, a connecting block, a hydraulic cylinder and a balance block. A sucker rod is installed in the oil well, and a rope is connected to the sucker rod. In the direction, there is a connecting block on the rope, a hydraulic cylinder is installed on the connecting block, and a balance block is arranged beside the oil well, and the balance block is connected with the sucker rod through the rope to move in parallel.

The sucker rods are two adjacent oil wells, and the adjacent sucker rods are connected together by the same rope; the rope is a steel wire rope; the hydraulic cylinder is a two-way hydraulic cylinder; the balance weight is installed on one side of the lighter sucker rod ; The rope is divided into two at the fixed pulley, and is connected with the balance weight and the sucker rod at the same time.

The utility model has the advantages that: the combined energy-saving pumping unit, its key lies in changing the energy consumed by a single pumping unit to lift the oil pipe to overcome gravity, and change it to the energy consumed by double oil and oil units to overcome the frictional resistance of the fixed pulley block, that is The useless work is greatly reduced, so the energy consumption is greatly reduced; and in modern drilling projects, it is generally used to drill multiple oil wells with different depths and different directions at the same well location, that is, cluster wells, and the distance between two adjacent wells is generally 2 meters about. Therefore, it is completely feasible to adopt a combined oil-oil machine, and it should have a broad market space.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in the figure, the combined energy-saving pumping unit includes an oil well 1, a sucker rod 2, a rope 3, a fixed pulley 4, a connecting block 5, a hydraulic cylinder 6 and a balance block 7, and the oil well 1 is installed with a sucker rod 2, A rope 3 is connected to the sucker rod 2, and the direction of the rope 3 is changed through a fixed pulley 4. A connecting block 5 is strung on the rope 3, and a hydraulic cylinder 6 is installed on the connecting block 5. A balance weight 7 is arranged beside the oil well 1, and the balance weight 7 is connected with the sucker rod 2 through the rope 3 and moves in parallel.

The sucker rod 2 is for two adjacent oil wells 1, and the adjacent sucker rods 2 are connected together by the same rope 3; 6 is driven, and the connecting block 5 is locked on the rope 3 through hydraulic pliers; the balance block 7 is installed on one side of the light sucker rod 2, and because the size and mass of the sucker rod 2 are not the same, it is adjusted by the balance block 7, Try to make equal loads on the left and right sides.

The rope 3 is divided into two at the fixed pulley 4, and is connected with the balance weight 7 and the sucker rod 2 at the same time.

How to use this device: After the hydraulic system supplies oil to the hydraulic cylinder 6, if the hydraulic rod stretches out, driven by the rope 3 and the fixed pulley 4, the sucker rod 2 on the right is lifted to carry out the oil pumping operation, and the sucker rod 2 on the left is The sucker rod 2 goes down, and the weight of the right sucker rod 2 is exactly offset by the weight of the left sucker rod 2, so that when the right sucker rod 2 is lifted, it is unnecessary to overcome the right sucker rod 2. The work to be done by the weight; when the hydraulic rod is retracted, the sucker rod 2 on the left side is lifted to carry out the oil pumping operation, so that the reciprocating motion carries out the oil pumping. In this way, the system mainly performs work by overcoming the frictional resistance, thereby avoiding the work done by lifting the gravity load of the sucker rod 2, the energy-saving effect is quite remarkable, and it is simple and practical.
