Description

Technical Field

[0001] The invention relates to equipment for unclogging oil pipes. Background Art

[0002] In the process of oil extraction, after drilling an oil well, it is necessary to pump up the crude oil from underground through an oil pipe. Currently, the most commonly used oil pipe is a seamless steel pipe. During the process of extracting crude oil, the crude oil mixed with impurities in the oil pipe is easy to clog the oil pipe, especially in high-altitude cold areas where there is permafrost underground. The crude oil mixed with impurities freezes in the oil pipe, clogging the oil pipe, causing oil extraction failure and the oil pipe being scrapped. Summary of the Invention

[0003] The purpose of the present invention is to provide an oil pipe dredging device.

[0004] The technical solution of the present invention is: an induction heating oil pipe dredging equipment, including a control console, an induction coil, the induction coil is arranged horizontally, the induction coil is installed on a coil bracket, the induction coil is a semicircular spiral, there are oil pipe support seats at both ends of the induction coil, a high-pressure pump is provided at one end of the induction coil, and a waste collection box is provided at the other end of the induction coil.

[0005] The induction coil is made of copper tube. One end of the copper tube is equipped with a positive terminal block and an induction coil cooling water inlet joint, and the other end is equipped with a negative terminal block and an induction coil cooling water outlet joint. The inlet pipe of the cooling water pump is connected to the circulating cooling water tank at one end, and the other end is connected to the induction coil cooling water inlet joint. The inlet pipe of the circulating cooling water tank is connected to the induction coil cooling water outlet joint. An insulating layer is wound on the induction coil.

[0006] The high-pressure pump is a high-pressure air pump or a high-pressure water pump, and an oil pipe plug is installed on the outlet of the high-pressure pump.

[0007] The high-pressure pump is installed on a track-traveling trolley.

[0008] An oil pipe support to be dredged is provided on one side of the induction coil, and an oil pipe support after dredging is provided on the other side.

[0009] The oil pipe support to be dredged and the oil pipe support after dredging are tilted at an angle of 10° to 15°. There is an oil pipe baffle to be dredged at the bottom end of the oil pipe support to be dredged, and there is a oil pipe baffle after dredging at the bottom end of the oil pipe support after dredging.

[0010] Oil pipe import and export mechanisms are respectively installed at both ends of the induction coil.

[0011] The oil pipe import and export mechanism includes a frame, on which a driving motor, a first driven wheel, and a second driven wheel are installed. The driving motor drives the first driven wheel and the second driven wheel respectively through the first driving wheel and the second driving wheel. The first driven shaft of the first driven wheel is connected to one end of the first crank arm, and the other end of the first crank arm is connected to the oil pipe import and export arm through the first crank arm shaft; the second driven shaft of the second driven wheel is connected to one end of the second crank arm, and the other end of the second crank arm is connected to the oil pipe import and export arm through the second crank arm shaft; an oil pipe import seat and an oil pipe export seat are installed above the oil pipe import and export arm.

[0012] The first crank arm shaft is connected to the oil pipe inlet and outlet arm through a first bearing; the second crank arm shaft is connected to the oil pipe inlet and outlet arm through a second bearing.

[0013] The first driving wheel, the second driving wheel, the first driven wheel and the second driven wheel are sprockets, and the first driving wheel and the second driving wheel drive the first driven wheel and the second driven wheel through chains.

[0014] The present invention has the following technical effects: since the blockage that blocks the oil pipe contains crude oil, or crude oil that has frozen through the permafrost layer, the present invention places the oil pipe in an induction coil, and uses induction heating to simultaneously achieve overall uniform heating (without open flame) of the core and surface of the oil pipe to soften or vaporize the blockage, and then leads high-pressure gas or high-pressure water to one end of the oil pipe to flush the blockage out of the oil pipe and unclog the oil pipe. An oil pipe can be unclogged in about 5 minutes, with high dredging efficiency. The induction heating temperature is controlled at about 200°C, and the oil pumping pipe does not deform after heating, ensuring that the mechanical properties of the oil pipe are not affected.

[0037] picture Figure 8 、 Figure 9 As shown, the oil pipe import and export mechanism 8 includes a frame 8-1, on which a drive motor 8-2, a first driven wheel 8-3 and a second driven wheel 8-4 are installed. The drive motor 8-2 drives the first driven wheel 8-3 and the second driven wheel 8-4 respectively through the first drive wheel 8-22 and the second drive wheel 8-23. The first driven shaft 8-31 of the first driven wheel 8-3 is connected to one end of the first crank arm 8-5, and the other end of the first crank arm 8-5 is connected to the oil pipe import and export swing arm 8-7 through the first crank arm shaft 8-51; the second driven shaft 8-41 of the second driven wheel 8-4 is connected to one end of the second crank arm 8-6, and the other end of the second crank arm 8-6 is connected to the oil pipe import and export swing arm 8-7 through the second crank arm shaft 8-61; an oil pipe import seat 8-8 and an oil pipe export seat 8-9 are installed above the oil pipe import and export swing arm 8-7.
