Environment-friendly continuous sucker rod operation assembly and operation process

Abstract

The invention discloses an environment-friendly continuous sucker rod operation assembly and an operation process, and relates to the technical field of oil field machinery, in particular to the environment-friendly continuous sucker rod operation assembly which comprises a sucker rod, a fixing base body is arranged on the periphery of the sucker rod, and a lead screw is installed on the lower side of the front face of the fixing base body. A rotating disc is fixedly installed at the front end of the lead screw, and the outer surface of the lead screw is in threaded connection with a threaded sleeve. According to the environment-friendly continuous sucker rod operation assembly and the operation process, the position of the threaded sleeve can be changed by rotating the rotating disc, so that the distance between the third heating assembly and the sucker rod is changed, and then heat received by the sucker rod is changed; when the external temperature reduces, the distance between the third heating assembly and the sucker rod can be reduced to increase the heating degree of the sucker rod, so that the problem of wax precipitation of crude oil is solved, meanwhile, the problem that power resources are wasted due to the fact that the power of the third heating assembly is increased traditionally is solved, and the operation cost is saved.

Description

technical field [0001] The invention relates to the technical field of oilfield machinery, in particular to an environment-friendly continuous sucker rod operation assembly and operation technology. Background technique [0002] The sucker rod is a slender rod of the pumping well. It is connected to the polished rod at the top and the oil pump at the bottom to transmit power. The temperature in the oil field is very high, and the temperature of the crude oil gradually decreases during the ascent in the tubing. When the temperature drops to the precipitation point of the wax, the wax will precipitate from the crude oil and adhere to the inner wall of the tubing, resulting in a decrease in the inner diameter of the tubing and affecting the production efficiency. In order to prevent wax precipitation, a common method is to install a sucker rod in the oil pipe. The sucker rod is actually a metal pipe, and a cable is installed inside it. Skin effect, the temperature of the outer...

Problems solved by technology

[0003] In the existing sucker rods, heating cables are usually installed inside the sucker rods to make the sucker rods heat up, but opening installation grooves inside the sucker rods will reduce the hardness and service life of the sucker rods, so some workers A heating device will be installed on the outside of the sucker rod to heat the surface of the sucker rod, but as the sucker rod will gradually rise during oil pumping, the surface temperature will still decrease, causing the wax oil to solidify and fall to the ground In addition, it is difficult to clean up, and it is difficult to collect the wax oil. When there is a lot of dust in the oil pumping environment, the dust will condense with the wax oil to form mud beads, causing wax oil pollution and cannot be used, and a heating device is installed outside It needs to be adjusted with the change of the external temperature. Usually, the staff will use the method of increasing the power of the heating component, but it will consume a lot of power resources. In view of this, an environmentally friendly continuous sucker rod operation assembly and work technology to solve the above problems
