Abstract
Description
Technical Field
[0001] This utility model relates to equipment for unclogging oil pipes. Background Technology
[0002] In the process of oil extraction, after drilling an oil well, crude oil needs to be extracted from the ground through oil pipes. Currently, the most commonly used oil pipes are seamless steel pipes. During the extraction of crude oil, crude oil mixed with impurities can easily clog the oil pipes, especially in high-altitude and cold regions where there is a permafrost layer underground. Crude oil mixed with impurities freezes in the oil pipes, clogging them, causing oil extraction failures, and rendering the oil pipes unusable. Utility Model Content
[0003] The purpose of this invention is to provide an oil pipe unblocking device.
[0004] The technical solution of this utility model is: an induction heating oil pipe unblocking device, including a control console, an induction coil, the induction coil being horizontally arranged and mounted on a coil support, the induction coil being semi-circular spiral, with oil pipe support seats at both ends of the induction coil, a high-pressure pump at one end of the induction coil, and a waste collection box 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 connector. The other end is equipped with a negative terminal block and an induction coil cooling water outlet connector. The inlet pipe of the cooling water pump is connected to a circulating cooling water tank at one end and to the induction coil cooling water inlet connector at the other end. The inlet pipe of the circulating cooling water tank is connected to the induction coil cooling water outlet connector. 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 at the outlet of the high-pressure pump.
[0007] The high-pressure pump is mounted on a track-moving trolley.
[0008] A support for the oil pipe to be cleared is provided on one side of the induction coil, and a support for the cleared oil pipe is provided on the other side.
[0009] The oil pipe support to be unclogged and the oil pipe support after unclogged are inclined at an angle of 10° to 15°. There is a baffle for the oil pipe to be unclogged at the bottom of the oil pipe support to be unclogged, and there is a baffle for the oil pipe after unclogged at the bottom of the oil pipe support after unclogged.
[0010] An oil inlet / outlet mechanism is installed at each end of the induction coil.
[0011] The described tubing inlet / outlet mechanism includes a frame, on which a drive motor, a first driven wheel, and a second driven wheel are mounted. The drive motor drives the first driven wheel and the second driven wheel respectively through the first drive wheel and the second drive wheel. The first driven shaft of the first driven wheel is connected to one end of a first crank arm, and the other end of the first crank arm is connected to the tubing inlet / outlet arm through a first crank arm shaft. The second driven shaft of the second driven wheel is connected to one end of a second crank arm, and the other end of the second crank arm is connected to the tubing inlet / outlet arm through a second crank arm shaft. A tubing inlet seat and a tubing outlet seat are mounted above the tubing inlet / outlet arm.
[0012] The first crank arm shaft is connected to the oil pipe inlet / outlet arm via the first bearing; the second crank arm shaft is connected to the oil pipe inlet / outlet arm via the second bearing.
[0013] The first drive wheel, second drive wheel, first driven wheel, and second driven wheel are sprockets, and the first drive wheel and second drive wheel drive the first driven wheel and second driven wheel through a chain.
[0014] This invention has the following technical advantages: Since the blockage in the oil pipe contains crude oil, or crude oil that has frozen through permafrost, this invention places the oil pipe in an induction coil. Through induction heating, the core and surface of the oil pipe are simultaneously and uniformly heated (without open flame), softening or vaporizing the blockage. Then, high-pressure gas or high-pressure water is introduced to one end of the oil pipe to flush out the blockage and clear the oil pipe. One oil pipe can be cleared in about 5 minutes, with high clearing efficiency. The induction heating temperature is controlled at around 200℃, and the heated oil pipe does not deform, ensuring that the mechanical properties of the oil pipe are not affected.

There is an oil pipe baffle 10-1 to be unclogged at the bottom of the oil pipe support 10 to be unclogged, and there is an oil pipe baffle 11-1 after unclogging at the bottom of the oil pipe support 11.
[0036] Oil pipe inlet / outlet mechanism 8 is installed at each end of the induction coil 4.
[0037] picture Figure 8 , Figure 9 As shown, the oil pipe inlet / outlet 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 mounted. 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 inlet / outlet 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 inlet / outlet swing arm 8-7 through the second crank arm shaft 8-61. An oil pipe inlet seat 8-8 and an oil pipe outlet seat 8-9 are mounted above the oil pipe inlet / outlet swing arm 8-7.
[0038] The first crank arm shaft 8-51 is connected to the oil pipe inlet / outlet swing arm 8-7 via the first bearing 8-52; the second crank arm shaft 8-61 is connected to the oil pipe inlet / outlet swing arm 8-7 via the second bearing 8-62.
[0039] The first drive wheel 8-22, the second drive wheel 8-23, the first driven wheel 8-3, and the second driven wheel 8-4 are sprockets. The first drive wheel 8-22 and the second drive wheel 8-23 drive the first driven wheel 8-3 and the second driven wheel 8-4 through the chain 8-21.
[0040] like Figure 10 As shown, the oil pipe to be unclogged is placed on the oil pipe support 10. The oil pipe support 10 is set at an angle. There is an oil pipe baffle 10-1 at the bottom of the oil pipe support 10. At this time, the oil pipe inlet and outlet swing arm 8-7 of the oil pipe inlet and outlet mechanism 8 is at the lowest point.
[0041] like Figure 11 As shown, the drive motor 8-2 of the oil pipe inlet / outlet mechanism 8 starts, and the chain 8-21 drives the first driven wheel 8-3 and the second driven wheel 8-4. The first driven wheel 8-3 and the second driven wheel 8-4 drive the first crank arm 8-5 and the second crank arm 8-6 to rotate.

After the oil pipe inlet / outlet swing arm 8-7 rotates 360° counterclockwise, the oil pipe 12 to be unclogged is placed on the oil pipe support seat 6. At this time, the induction coil 4 is activated to heat the oil pipe 12 to be unclogged. The heating temperature is controlled at about 200°C, which melts the blockage on the inner wall of the oil pipe 12. After heating, high-pressure air or high-pressure water is used to flush the blockage out of the pipe into the waste collection box 9, thus unclogging the oil pipe 12.
