Description

Technical Field

[0001] The utility model relates to the technical field of fracturing pipelines, in particular to a fracturing pipeline with a wear-resistant protective layer. Background Art

[0002] In the field of oil and gas extraction, fracturing refers to a technology that uses high-pressure fracturing fluid to create cracks in oil and gas layers during the oil or gas production process. The fracturing pipeline used for fracturing operations is usually used to transport fracturing fluid carrying fracturing sand, and therefore needs to have strong wear resistance.

[0003] Acid fracturing hoses with a multi-layer composite structure are commonly used in fracturing pipelines. A wrapped steel wire layer is provided on the outside of the hose's wear-resistant layer to provide structural support for the hose, ensuring that the hose will not deform or rupture under high pressure, while also increasing the hose's wear resistance. However, the steel wires in the steel wire layer are usually wrapped around the wear-resistant layer in a clockwise or counterclockwise manner. When a certain part of the steel wire is worn, it will pull the surrounding steel wires along the worn part, making it unable to be effectively protected, resulting in increasingly severe wear.

[0004] Therefore, a fracturing pipeline is needed that can prevent the expansion of the wear portion along the steel wire. Utility Model Content

[0005] In response to the deficiencies of the prior art, the utility model provides a fracturing pipeline with a wear-resistant protective layer, which is simple, efficient, safe, reliable, and easy to operate, and which has steel wires A and B that are intertwined into a mesh structure and limit each other's positions to prevent the worn parts along the steel wires from expanding outward.

[0006] The utility model is realized by the following technical scheme, which provides a fracturing pipeline with a wear-resistant protective layer, including a plurality of wear-resistant layers sequentially sleeved from the inside to the outside along the radial direction of the pipeline; a plurality of steel wires A and steel wires B are wound around the outside of each wear-resistant layer, and the winding directions of the steel wires A and the steel wires B are opposite. A mesh structure is formed between the steel wires A and the steel wires B, and the intersecting parts of the steel wires A and the steel wires B are intertwined with each other; the steel wires A and the steel wires B intertwined to form a mesh structure limit each other's positions, thereby increasing the mechanical strength of the pipeline and preventing the wear parts along the steel wires from expanding outward, thereby effectively resisting the wear of the internal fluid and the external environment.

[0007] As an optimization, the intersection of steel wire A and steel wire B is twisted around each other multiple times along the pipeline axis to increase the strength of the connection between steel wire A and steel wire B and prevent the wear area along the steel wire from expanding outward.

[0008] As an optimization, the steel wires A and B on the outside of the same wear-resistant layer are the same and have the same winding angle values; ensuring that the steel wires A and B provide the same supporting force to the pipeline to prevent the pipeline from deformation.

[0009] As an optimization, the diameter and strength of the steel wire A close to the pipeline axis are respectively lower than the diameter and strength of the steel wire A far from the pipeline axis; the wear resistance of the pipeline is increased layer by layer from the inside to the outside along the radial direction of the pipeline.

[0010] As an optimization, the elongation of the steel wire A close to the pipeline axis is higher than the elongation of the steel wire A far from the pipeline axis, ensuring the flexibility of the pipeline.

[0011] As an optimization, the winding angle value of the steel wire A close to the pipeline axis is smaller than the winding angle value of the steel wire A far from the pipeline axis, ensuring the flexibility of the pipeline.

[0012] As an optimization, steel wire A and steel wire B are arranged evenly around the pipeline in sequence; ensuring that steel wire A and steel wire B provide the same supporting force to each part of the pipeline to prevent the pipeline from deformation.

[0013] As an optimization, the steel wires A and B outside the adjacent wear-resistant layers are staggered along the radial direction of the pipeline; by setting the positions of the steel wires A and B in the adjacent wear-resistant layers to be different, the wear resistance of the pipeline is increased.

[0014] The beneficial effects of the utility model are as follows: the steel wires A and B that are intertwined into a mesh structure limit each other's positions, thereby increasing the mechanical strength of the pipeline and preventing the wear parts along the steel wires from expanding outward, thereby effectively resisting the wear of internal fluids and the external environment; by arranging the positions of the steel wires A and B at different levels through adjacent wear-resistant layers, the wear resistance of the pipeline is increased.

[0019] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0020] like Figure 1 The fracturing pipeline with a wear-resistant protective layer shown in the utility model includes multiple wear-resistant layers 1 that are sequentially sleeved from the inside to the outside along the radial direction of the pipeline; multiple steel wires A2 and steel wires B3 are wrapped around the outside of each wear-resistant layer 1, and the winding directions of the steel wires A2 and the steel wires B3 are opposite. A mesh structure is formed between the steel wires A2 and the steel wires B3, and the intersection of the steel wires A2 and the steel wires B3 is intertwined.

[0021] Multiple steel wires A2 and steel wires B3 are wound around the outside of each wear-resistant layer 1 of the pipeline, and the winding directions of the steel wires A2 and B3 are opposite. The intersecting parts of the steel wires A2 and B3 are wound together, so that a steel wire mesh is formed between the steel wires A2 and B3 outside each wear-resistant layer 1 and is sleeved on the corresponding wear-resistant layer 1.

[0022] like Figure 1 As shown, the intersection of the steel wire A2 and the steel wire B3 is entangled with each other multiple times along the axial direction of the pipeline.

[0023] like Figure 1 The steel wires A2 and B3 on the outside of the same wear-resistant layer 1 are identical and have the same winding angle values.

[0024] like Figure 1 The diameter and strength of the steel wire A2 shown closer to the pipeline axis are respectively lower than the diameter and strength of the steel wire A2 further away from the pipeline axis.

[0025] like Figure 1 It is shown that the elongation of the steel wire A2 close to the pipeline axis is higher than the elongation of the steel wire A2 far from the pipeline axis.

[0026] like Figure 1 As shown, the winding angle value of the steel wire A2 close to the pipeline axis is smaller than the winding angle value of the steel wire A2 far from the pipeline axis.

[0027] like Figure 1 The steel wires A2 and B3 are shown to be evenly arranged in sequence around the pipeline.

[0028] like Figure 1 and Figure 2 As shown, the steel wires A2 and B3 outside the adjacent wear-resistant layers 1 are staggered along the radial direction of the pipeline.

[0029] In the actual production process, a plurality of steel wires A2 and steel wires B3 are wound around the outside of each wear-resistant layer 1 of the pipeline, and the winding directions of the steel wires A2 and steel wires B3 are opposite. The intersection of the steel wires A2 and steel wires B3 is wound around each other multiple times along the axial direction of the pipeline, so that a steel wire mesh is formed between the steel wires A2 and steel wires B3 outside each wear-resistant layer 1 and is sleeved on the corresponding wear-resistant layer 1. The steel wires A2 and steel wires B3 outside adjacent wear-resistant layers 1 are staggered along the radial direction of the pipeline.
