Problems solved by technology

[0002] The anti-wear sleeve of the existing drilling rig adopts a composite structure with an inner layer of engineering plastic and an outer layer of metal material, and the process is relatively complicated. The inner layer of engineering plastic in this structure can protect the drill pipe located in the inner hole of the anti-wear sleeve from being worn. The outer layer of metal can improve the strength of the wear-resistant sleeve and avoid the damage of the wear-resistant sleeve when it interferes with the sleeve outside the wear-resistant sleeve. However, when the outer metal interferes with the sleeve, it is easy to wear and tear the sleeve. After the casing is worn and broken, it will cause water and oil leakage, which must be repaired. The maintenance process is extremely complicated and time-consuming, resulting in a large amount of maintenance work, which seriously affects the drilling efficiency and greatly reduces the drilling progress.

Embodiment Construction

[0008] see Figure 1 ~ Figure 2 , The anti-wear sleeve of the drilling rig of the present invention includes an anti-wear sleeve 1, and the anti-wear sleeve 1 is composed of a plastic body 2. The plastic body 2 is a wear-resistant plastic body with large contact stress, good compressibility, resilience and manufacturability, which not only protects the wear-resistant sleeve 1 itself from being damaged, but also protects the drill pipe 3 located in the inner hole of the wear-resistant sleeve from being damaged. The casing 4 that is worn and located outside the wear sleeve is not worn and broken. The anti-wear sleeve 1 is a circular tubular structure.

Abstract

The invention relates to an abrasion-resistant sleeve of a drilling machine. The abrasion-resistant sleeve of the drilling machine comprises an abrasion resistant sleeve (1) formed by a plastic body (2) which is an abrasion-resistant plastic body. The abrasion-resistant sleeve (1) is of a round tube structure. The abrasion-resistant sleeve of the drilling machine has good resilience, abrasion resistance, shock resistance, tearing resistance, fatigue resistance, good sealing performance and long service life, thereby being widely applied to petroleum drilling machines.

Description

Technical field: [0001] The invention relates to an oil drilling rig, in particular to an anti-friction sleeve for an oil drilling rig. Background technique: [0002] The anti-wear sleeve of the existing drilling rig adopts a composite structure with an inner layer of engineering plastic and an outer layer of metal material, and the process is relatively complicated. The inner layer of engineering plastic in this structure can protect the drill pipe located in the inner hole of the anti-wear sleeve from being worn. The outer layer of metal can improve the strength of the wear-resistant sleeve and avoid the damage of the wear-resistant sleeve when it interferes with the sleeve outside the wear-resistant sleeve. However, when the outer metal interferes with the sleeve, it is easy to wear and tear the sleeve. After the casing is worn and ruptured, water leakage and oil leakage must be carried out. The maintenance process is extremely complicated and time-consuming, resulting in...
