Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings:

[0025] like figure 1 As shown, the present invention includes an oil pipe body 1, the upper and lower ends of the oil pipe body 1 are respectively provided with an upper joint and a lower joint, and the inner side of the upper joint and the outer side of the lower joint are respectively processed with matching standard oil pipe sealing tapered threads 5, which are connected The two oil pipes are still connected through the conventional standard oil pipe sealing taper thread 5, which can fully guarantee the sealing performance and connection strength of the oil pipe joint, and is compatible with all conventional downhole tools.

[0026] like figure 1 As shown, the inner side of the oil pipe body 1 is provided with an inner liner 4 made of stainless steel, the inner liner 4 extends upward to the lowermost end of the inner thread of the upper joint, and extends downward ...

Abstract

The invention belongs to the field of oil field oil extraction equipment, and in particular relates to an anti-corrosion oil conveying pipeline. The anti-corrosion oil conveying pipeline comprises an oil pipe body, wherein an upper joint and a lower joint are arranged at the upper and lower ends of the oil pipe body respectively, standard oil pipe sealing cone threads matched with each other are machined on the inner side of the upper joint and the outer side of the lower joint, respectively, a liner layer made from a stainless steel material is arranged on the inner side of the oil pipe body, the liner layer extends upwards to the lowermost end of the thread on the inner side of the upper joint and extends downwards to the lower end surface of the oil pipe body. As the stainless steel liner layer is arranged on the inner side of the oil pipe, corrosion resistance of the oil pipe can be improved effectively. In addition, an electric heating layer is arranged on the wall of the oil pipe to heat the oil pipe electrically, so that scaling of the pipe wall can be reduced and corrosion to the oil pipe by chemical components in scale is reduced, and therefore, the corrosion resistance of the oil pipe is further improved.

Description

technical field [0001] The invention belongs to the field of oil production equipment in oil fields, and in particular relates to an anti-corrosion oil pipeline. Background technique [0002] Oil pipelines are commonly used infrastructure in oilfield production, but in actual use, under the action of complex physical and chemical environments, the inner wall of the oil pipeline is easily corroded, which affects the service life of the oil pipeline. Therefore, it is necessary to design a better oil pipe with anti-corrosion performance to solve the above problems. Contents of the invention [0003] The present invention provides an anti-corrosion oil delivery pipeline to solve the problems raised in the above-mentioned background technology. [0004] The technical problem solved by the present invention adopts following technical scheme to realize: [0005] An anti-corrosion oil delivery pipeline, comprising a pipeline body, the upper and lower ends of the pipeline body ar...
