Description

Technical Field

[0001] The present invention relates to the technical field of oil well single well tanks, and in particular to a heating device for an oil well single well tank and a use method thereof. Background Art

[0002] During crude oil production in oil fields, some remote wells cannot be transported via pipelines due to low production or long distances from metering stations. Therefore, individual oil storage tanks are installed at the well site to temporarily store the crude oil produced by the wells and transport it regularly by truck. Because the temperature of crude oil in the tanks drops rapidly, especially in winter, the viscosity of the crude oil increases after cooling, making it difficult to transport. Therefore, the crude oil in the tanks must be heated before transportation.

[0003] Traditional heating methods mostly install the heating rod directly at the center of the tank, and then heat the oil in the tank through the heating rod. The central heating rod heats the oil in the tank through heat conduction, resulting in slow heating efficiency. At the same time, during the heating process, the oil far away from the heating rod cannot be fully and evenly heated, resulting in a part of the oil having a high viscosity and being unable to be discharged and transported. At the same time, the oil close to the heating rod will cause the local temperature to be too high during the continuous heating process, causing some high-temperature volatile substances in the oil to evaporate, thereby reducing the quality of the heated oil.

[0021] Step 3: Perform inspection and maintenance on the devices in the tank every 15 days.

[0022] The beneficial effects of the present invention:

[0023] (1) Drive the mounting block to rotate through the drive mechanism. At the same time, drive the mounting pipe to move left and right reciprocally and rotate through the first electric telescopic rod on the mounting block. Then drive the transmission disk to move through the transmission mechanism, thereby driving the transmission pipe to open at multiple angles. Subsequently, through the cooperation of the flow heating mechanism, uniform circulating heating of the petroleum in the tank from the inside to the outside is realized, greatly improving the heating speed of the petroleum. At the same time, layered circulating heating is achieved, which will not cause overheating of local petroleum, resulting in excessive heating temperature in this local petroleum and volatilization of volatile gases, leading to a reduction in the quality of the petroleum. Thus, the heating efficiency and heating effect of the petroleum are improved.

[0024] (2) During the circulating heating process, drive the spiral cleaning rod in the spiral heating elbow to move left and right to clean the inner wall of the spiral heating elbow. At the same time, while the transmission pipe is rotating, the cleaning ring in the transmission pipe moves reciprocally under the action of the counterweight to clean the inner wall of the transmission pipe. Thus, self-cleaning of the inner walls of the transmission pipe and the spiral heating elbow during the circulating heating process is realized, preventing excessive adhesion of impurities on the pipe wall during long-term circulating heating, resulting in a decrease in pipe diameter or blockage, which affects the effect of circulating heating. Thus, the stability of the use of the heating device is improved.

[0025] (3) When it is necessary to clean the inside of the tank, at this time, add cleaning liquid into the tank, and then the pump body works. The pump body sucks the cleaning liquid in the tank, and at the same time heats the cleaning liquid through the spiral heating elbow to improve the cleaning effect. Subsequently, by controlling the opening angle of the transmission pipe, the transmission pipe is tilted at multiple angles to wash the inner wall of the tank, so that the stains on the inner wall are washed down. At the same time, cooperate with the mounting pipe to drive the mounting column, cleaning plate and cleaning brush to rotate, and the cleaning brush brushes the inner wall of the tank, thereby realizing full automatic cleaning of the inner wall of the tank.

[0026] (4) Drive the transmission pipe to tilt and rotate at multiple angles through the mounting pipe. The transmission pipe drives the bubble piercing rod to rotate in the petroleum, pierce the bubbles in the petroleum at multiple positions in the tank, fully discharge the gas in the petroleum, reduce the air pressure in the tank, and at the same time increase the oil storage space in the tank, so that more petroleum can be stored in the tank.

[0057] The mounting tube drives the transmission tube 13 to rotate at multiple angles, and the transmission tube 13 drives the bubble puncturing rod 61 to rotate in the oil, puncturing the bubbles in the oil at multiple positions in the tank body 1, so that the gas in the oil is fully discharged, reducing the air pressure in the tank body 1, and increasing the oil holding space of the tank body 1, so that more oil can be stored in the tank body 1.

[0058] Example 5

[0059] A method for using a heating device for a single-well tank of an oil well, comprising the following steps:

[0060] Step 1: Rotate and install the installation block 2 on the tank body 1, and then connect the tank body 1 to the oil well output pipe;

[0061] Step 2: When the temperature is too low, start the driving mechanism and the first electric telescopic rod 5 at this time, and at the same time start the circulating heating mechanism on the installation pipe 3, and then realize full circulating heating of the petroleum in the tank body 1;

[0062] Step 3: Overhaul and maintain the devices in the tank body 1 every 15 days.

[0063] Working principle of the present invention: The driving mechanism drives the driving disk 15 to move. The driving disk 15 drives the driving pipe 13 to rotate in the first installation groove 12 on the installation disk 11 through the driving plate 17 and the driving frame 18, so that the driving pipe 13 slowly opens in the tank body 1. When it opens to 10°, it stops. At this time, the pump body 23 works. The pump body 23 sucks oil from the first circle of pipes 22 through the pipeline. The first circle of pipes 22 sucks oil from the driving pipe 13 in the upper half of the installation pipe 3 through the first connecting pipe 21 and the hose 14. At this time, multiple driving pipes 13 suck the petroleum in the tank body 1 into the pump body 23. The pump body 23 passes the sucked petroleum into the spiral heating elbow 24 through the pipeline, and it flows in the spiral heating elbow 24. While flowing, the second electric telescopic rod 27 drives the connecting disk 28 to move left and right. The connecting disk 28 drives multiple electric heating rods 29 to move left and right reciprocally. The electric heating rods 29 uniformly heat the spiral heating elbow 24. At the same time, the spiral heating elbow 24 uniformly heats the petroleum flowing inside. At the same time, the driving mechanism drives the installation pipe 3 to rotate. The installation pipe 3 drives the driving pipe 13 to rotate. The driving pipe 13 rotates in the tank body 1, and sucks the petroleum at the 10° position level of the driving pipe 13 in the tank body 1 into the spiral heating elbow 24 for uniform heating. The petroleum heated by the spiral heating elbow 24 is passed into each second connecting pipe 26 through the second circle of pipes 25. Subsequently, the second connecting pipe 26 passes the petroleum into the driving pipe 13 in the lower half of the installation pipe 3 through the hose 14, and then discharges it into the tank body 1 through the driving pipe 13, realizing the uniform heating of the circulation of the petroleum at this level. Subsequently, the driving pipe 13 is driven to rotate to 20° to carry out the circulation heating of the petroleum at this level, and so on, until the driving pipe 13 rotates to 90°, realizing the uniform circulation heating of the petroleum in the tank body 1 from the inside to the outside, greatly improving the heating speed of the petroleum. At the same time, the layered circulation heating is realized, which will not cause overheating of the local petroleum, resulting in the problem that the heating temperature of the local petroleum is too high and the volatile gas volatilizes, resulting in the reduction of the quality of the petroleum. Thus, the heating efficiency and heating effect of the petroleum are improved.
