Ground pipeline corrosion prevention device for oil field and operating method

Abstract

The invention discloses a ground pipeline corrosion prevention device for an oil field and an operating method. The ground pipeline corrosion prevention device comprises outer corrosion prevention pipes, oil pipes, supporting rings, a polyamide epoxy resin layer, rubber rings, a 3PE pyrocondensation material, a casing, a locking disk, a high density polyethylene layer and epoxy coal tar pitch. Theoil pipes are arranged inside the outer corrosion prevention pipes. The outer corrosion prevention pipes are provided with outer pipe inner holes. Connecting rings are arranged at one ends of the outer corrosion prevention pipes. The two adjacent outer corrosion prevention pipes are connected. The connecting rings are matched with the outer pipe inner holes and further connected with the corresponding outer pipe inner holes through threads. The two adjacent oil pipes are connected. The outer sides of the supporting rings are matched with the outer pipe inner holes and further inserted into the corresponding outer pipe inner holes. The supporting rings are provided with supporting ring inner holes. The outer sides of the rubber rings are matched with the supporting ring inner holes and further connected with the corresponding supporting ring inner holes. Rubber sleeve inner holes are formed in the rubber rings. The outer sides of the oil pipes are matched with the rubber sleeve inner holes and further connected with the corresponding rubber sleeve inner holes.

Description

technical field [0001] The invention relates to the field of oil fields, in particular to an anti-corrosion device and an operation method for surface pipelines in oil fields. Background technique [0002] In the use of surface pipelines in oil fields, in order to avoid corrosion of pipelines during use, anti-corrosion measures are required for pipelines. However, the existing anti-corrosion pipelines only use anti-corrosion coatings on the surface of pipelines, and the anti-corrosion effect is limited. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a double anti-corrosion anti-corrosion device for surface pipelines in oil fields and an operation method. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] An anti-corrosion device for surface pipelines in oil fields, including anti-corrosion outer pipes, oil pipes, support rings, polya...
