Problems solved by technology

[0003] The purpose of the present invention is to clean the outer surface of the sand control cylinder through the cleaning plate on the vertical rod, clean the attached sand, and then improve the oil inlet efficiency of the equipment, so that the spoiler can stir the crude oil, so that the crude oil It is mixed with the gas, so it can not only achieve the effect of sand prevention and self-cleaning on the equipment, but also help to improve the filling degree of the equipment pumping. By forcing the positioning valve ball to open, the filling degree of the pump chamber can be increased to avoid As a result, the "air lock" phenomenon occurs after the opening of the positioning valve ball of the oil well pump, which solves the existing problem of the opening lag of the positioning valve ball. Leakage, brought to the ground to pollute the environment

Embodiment 1

[0023] Example 1: see Figure 1-8 As shown, the present invention is an oil pump for well cleaning, comprising a pump barrel 1, an elongated plunger 2 is slidably connected to the inside of the pump barrel 1, and an oil pulling rod 3 is fixedly connected to the upper surface of the elongated plunger 2. Pull the oil rod 3, so that the oil rod 3 drives the elongated plunger 2 to reciprocate up and down inside the pump cylinder 1, and a guide mechanism 4 is provided inside the pump cylinder 1 outside the oil rod 3, and in the pump cylinder 1 The lower end of the upper joint 5 is fixedly connected with an upper joint 5, the lower end of the upper joint 5 is fixedly connected with a thick barrel 6, the end of the thick barrel 6 away from the upper joint 5 is fixedly connected with an oil drain mechanism 7, and the lower end of the oil drain mechanism 7 is fixedly connected with an oil inlet barrel 8, and the oil inlet tube 8 and the coarse tube 6 cooperate with each other, the lowe...

Embodiment 2

[0024] Example 2: A cleaning assembly 10 is rotatably connected to the interior of the sand control cylinder 9, and the cleaning assembly 10 includes a driven rotating shaft 101, and a driven fan 102 is sleeved on the outside of the driven rotating shaft 101. From the sand control cylinder 9 into the oil inlet cylinder 8, the crude oil has fluidity, and then the crude oil drives the driven fan 102 outside the driven rotating shaft 101 to rotate during the flowing process. The lower end of the driven rotating shaft 101 is fixedly connected with a The base 104, the driven rotating shaft 101 is sleeved with a positioning sleeve 103, and the positioning sleeve 103 is movably connected with the sand control cylinder 9, and when the driven fan 102 drives the driven rotating shaft 101 to rotate, the driven rotating shaft 101 drives the positioning The shaft sleeve 103 rotates accordingly, and then generates the power of the transmission, and the two sides of the positioning shaft slee...

Embodiment 3

[0025] Example 3: When cleaning the equipment, the elongated plunger 2 is taken out from the inside of the pump barrel 1 through the oil rod 3, and then the inside of the pump barrel 1 is pressed. Then, the pressure above the oil drain mechanism 7 is stronger than the pressure below, and the oil drain mechanism 7 includes an oil drain barrel 01, and the inside of the oil drain barrel 01 is fixedly connected with a fixed rod 02, and the inside of the oil drain barrel 01 is located in the fixed plug ball The top of 04 is fixedly connected with a return pipe 06, the upper end of the fixed rod 02 is sleeved with a telescopic rod 03, the side of the telescopic rod 03 away from the fixed rod 02 is fixedly connected with a fixed blocking ball 04, and the upper surface of the fixed blocking ball 04 is fixed Connect the limit spring 05, the end of the limit spring 05 away from the fixed blocking ball 04 is fixedly connected with the thick barrel 6, and then when the pressure above the o...

Abstract

The invention relates to the technical field of oil well pump equipment, in particular to an oil well pump for well cleaning, which includes a pump barrel, an extended plunger is slidably connected to the inside of the pump barrel, and an oil pulling rod is fixedly connected to the upper surface of the extended plunger. The inside is located on the outside of the oil rod and a guide mechanism is installed. The lower end of the pump cylinder is fixedly connected with an upper joint, and the lower end of the upper joint is fixedly connected with a thick tube. The lower end is fixedly connected with an oil inlet cylinder; in the present invention, the driven fan outside the driven shaft is driven to rotate by the crude oil in the process of flowing, so that the support rod drives the cleaning plate on the vertical rod to clean the outer surface of the sand control cylinder , improve the oil inlet efficiency of the equipment, and also stir the crude oil through the spoiler to mix the crude oil and gas, so it can not only achieve the effect of sand prevention and self-cleaning of the equipment, but also help to improve the oil pumping capacity of the equipment degree.

Description

technical field [0001] The invention relates to the technical field of oil pump equipment, in particular to an oil pump for well cleaning. Background technique [0002] The oil well pump refers to the downhole device that is driven by the pumping unit to lift the crude oil in the well to the ground. It is mainly composed of four parts: the pump barrel, the suction valve, the piston and the exhaust valve. According to the fixing method of the oil well pump, it can be divided into tubular type. Pumps and rod pumps, and the existing oil-draining oil-pumping pumps on the market mostly use the form of openings in the pump body to drain oil; in the bulletin No. CN203257647U discloses a kind of oil-pumping pump that can flush wells with positive circulation. The oil well pump includes a pump barrel, a sucker rod, and a piston. The rear end of the piston is connected to the sucker rod. The front end of the piston is provided with a floating valve, and the pump barrel is provided wit...
