Description

Technical Field

[0001] The utility model relates to the technical field of fracturing pipelines, in particular to a fracturing pipeline damage detection device. Background Art

[0002] Acid fracturing technology is a process commonly used in oil and gas extraction. It injects acidic liquid to enhance the connectivity of the well wall pores and increase production capacity. In oil and gas fracturing operations, the fracturing pipeline has important tasks such as providing pressure for the fracturing fluid, transporting the fracturing fluid to the wellhead, and controlling the flow rate of the fracturing fluid. The fracturing fluid contains a large amount of fracturing sand, which often damages the fracturing pipeline. At the same time, the external environment will also cause certain wear and tear on the fracturing pipeline. If the worn fracturing pipeline is not replaced in time, various accidents are likely to occur, seriously affecting production efficiency.

[0003] Therefore, a device is needed to detect the damage condition of the fracturing pipeline. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a fracturing pipeline damage detection device which uses a light source transmitting device and a light receiver to detect whether an optical fiber is damaged, thereby detecting damage to the fracturing pipeline. The device is simple, efficient, safe, reliable and easy to operate.

[0005] The utility model is realized by the following technical solution, providing a fracturing pipeline damage detection device, including a light source emitting device and a light receiver respectively arranged at both ends of the pipeline, the light source emitting device and the light receiver being connected by an optical fiber, and the optical fiber being fixedly arranged on the outside of the pipeline wear-resistant layer; the light source emitting device and the light receiver detect whether the optical fiber is damaged, thereby detecting damage to the fracturing pipeline.

[0006] As an optimization, the optical fiber extends along the axial direction of the pipeline, and the optical fibers are arranged in sequence along the circumference of the pipeline; the location where the pipeline is prone to wear is determined by the damaged optical fiber.

[0007] As an optimization, the optical fibers are evenly arranged in sequence along the circumference of the pipeline; different parts of the pipeline are detected by evenly arranging the optical fibers in sequence along the circumference of the pipeline.

[0008] As an optimization, the pipeline includes multiple wear-resistant layers sequentially sleeved from the inside to the outside along the radial direction of the pipeline, and optical fibers are respectively arranged on the outside of each wear-resistant layer; the degree of wear of the pipeline is detected by the optical fibers sequentially arranged from the inside to the outside along the radial direction of the pipeline.

[0009] The beneficial effects of the utility model are as follows: the damage of the fracturing pipeline can be detected by detecting whether the optical fiber is damaged through the light source emitting device and the light receiver; the direction of the pipeline prone to wear is determined by the damaged optical fiber; different parts of the pipeline can be detected by arranging the optical fibers in a uniform manner along the circumference of the pipeline; and the degree of wear of the pipeline can be detected by arranging the optical fibers in a radial direction from the inside to the outside.

[0015] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0016] like Figure 1 and Figure 3 The fracturing pipeline damage detection device of the present invention shown includes a light source emitting device 3 and a light receiver 4 respectively arranged at both ends of the pipeline 1. The light source emitting device 3 and the light receiver 4 are connected by an optical fiber 5, and the optical fiber 5 is fixed on the outside of the wear-resistant layer 101 of the pipeline 1; the two ends of the pipeline 1 are respectively connected to a high-voltage connector 2.

[0017] The wear-resistant layer 101 of the pipeline 1 is usually made of ultra-high molecular weight polyethylene and high-density polyethylene. The melting point of ultra-high molecular weight polyethylene is between 130 and 136°C, and the softening point of high-density polyethylene is 125 to 135°C. The optical fiber uses high-temperature resistant optical fiber. The short-term use temperature of high-temperature resistant optical fiber can reach 350°C, and the long-term use temperature is -20°C to +300°C. The applicable temperature range of optical fiber with metal coating is from -270 to 700°C.

[0018] The light source emitting device 3 emits light at one end of the pipeline 1 and transmits it through the optical fiber 5. The light receiver 4 receives the light transmitted by the optical fiber 5 at the other end of the pipeline 1. If a part of the pipeline 1 is worn and causes damage to the optical fiber 5, the receiver detects that the light transmitted by the damaged optical fiber 5 is disconnected, thereby confirming that the pipeline 1 is damaged.

[0019] like Figure 1 and Figure 2 The optical fibers 5 shown extend axially along the pipeline 1 , and the optical fibers 5 are arranged sequentially along the circumference of the pipeline 1 .

[0020] The receiver detects that the light transmitted by the damaged optical fiber 5 is disconnected, thereby confirming that a certain portion of the pipeline 1 in the extending direction of the optical fiber 5 is worn, and further confirming that a certain portion of the pipeline 1 in the extending direction of the optical fiber 5 is prone to wear.

[0021] like Figure 1 and Figure 2 The optical fibers 5 are shown to be evenly arranged in sequence along the circumference of the pipeline 1 .

[0022] The light is evenly distributed around the pipe 1 and guided on the optical fiber 5 .

[0023] like Figure 1 and Figure 2 The pipeline 1 shown includes multiple wear-resistant layers 101 sequentially sleeved from the inside to the outside along the radial direction of the pipeline 1, and optical fibers 5 are respectively arranged on the outside of each wear-resistant layer 101; the optical fibers 5 and the wear-resistant layers 101 are alternately distributed in the radial direction of the pipeline 1.

[0024] Several wear-resistant layers 101 at a certain part of the pipeline 1 wear out in turn, and the optical fiber 5 corresponding to the wear-resistant layer 101 is damaged at once. The receiver detects that the light transmitted by the damaged optical fiber 5 is disconnected, and confirms that the pipeline 1 is internally worn or externally worn through the damaged optical fiber 5.

[0025] In the actual production process, the source emitting device emits light at one end of the pipeline 1 and transmits it through the optical fiber 5. The light evenly surrounds the pipeline 1 and is transmitted on the optical fiber 5. The optical receiver 4 receives the light transmitted by the optical fiber 5 at the other end of the pipeline 1. A certain part of the pipeline 1 is worn and causes damage to the optical fiber 5. The receiver detects that the light transmitted by the damaged optical fiber 5 is disconnected, thereby confirming that the pipeline 1 is damaged, thereby confirming that a certain part of the pipeline 1 in the extension direction of the optical fiber 5 is worn, and then confirming that a certain part of the pipeline 1 in the extension direction of the optical fiber 5 is prone to wear.

[0026] Several wear-resistant layers 101 at a certain part of the pipeline 1 wear out in turn, and the optical fiber 5 corresponding to the wear-resistant layer 101 is damaged at once. The receiver detects that the light transmitted by the damaged optical fiber 5 is disconnected, and confirms that the pipeline 1 is internally worn or externally worn through the damaged optical fiber 5.
