It usually adopts a multi-layer composite structure to cope with complex underground conditions. The inner layer is a corrosion-resistant layer, generally made of high-performance synthetic rubber or special plastic materials, which can effectively resist the erosion of chemical substances such as acid fracturing fluid; The middle layer is a reinforcement layer, woven from high-strength steel wires or fibers, providing the necessary tensile strength and compressive strength; The outer layer is a wear-resistant protective layer made of special wear-resistant materials to resist the wear of hard particles such as rock fragments and sand particles. 2、 Material selection In terms of material selection, the ultra wear-resistant acid fracturing hose focuses on the comprehensive performance of the material, striving to find the best balance between corrosion resistance, wear resistance, strength, and weight. The inner layer material needs to have excellent chemical stability and temperature resistance to ensure long-term use without failure; The reinforcement layer material emphasizes high strength and low elongation to improve the pressure bearing capacity and dimensional stability of the hose; The wear-resistant layer material is the focus of technological innovation. By introducing advanced technologies such as nanomaterials and ceramic particles, the wear resistance of the hose is significantly improved and the service life is extended. 3、 Manufacturing process and quality The manufacturing process of ultra wear-resistant acid fracturing hoses is complex and refined, involving multiple stages such as extrusion, weaving, vulcanization, and testing. During the production process, it is necessary to strictly control the quality of raw materials, process parameters, and production environment to ensure that each process meets the design requirements. At the same time, advanced online monitoring systems and quality control systems are adopted to conduct comprehensive quality inspections on hoses, including but not limited to appearance inspection, size measurement, pressure testing, corrosion resistance testing, and wear resistance testing, to ensure stable and reliable product quality. 4、 Performance characteristics and application advantages The ultra wear-resistant acid fracturing hose has demonstrated significant application advantages in oil and gas field development due to its unique performance characteristics. Firstly, its excellent wear resistance enables the hose to remain intact for a long time in high-pressure injection and high-speed flow of acid fracturing fluid, greatly reducing replacement frequency and operating costs. Secondly, good corrosion resistance and temperature resistance ensure the stable operation of the hose under harsh working conditions, improving the safety and reliability of the operation. In addition, the hose design is flexible, easy to install and transport, highly adaptable, and can meet different well conditions and operational needs. 5、 Application Cases and Effect Analysis In recent years, ultra wear-resistant acid fracturing hoses have been widely used in multiple oil and gas field projects both domestically and internationally. Taking a certain overseas oil field as an example, the field uses ultra wear-resistant acid fracturing hoses for large-scale fracturing operations. Compared with traditional hoses, its service life has been nearly doubled, and the operating efficiency has been significantly improved, while reducing downtime and maintenance costs caused by hose damage. In addition, the excellent sealing performance and pressure bearing capacity of the hose effectively avoid safety hazards such as fracturing fluid leakage, ensuring operational safety. With the development of oil and gas exploration and development towards deeper, farther, and more complex fields, the technical requirements for ultra wear-resistant acid fracturing hoses will continue to increase. In the future, this field will pay more attention to the innovation and application of materials, such as developing new high-performance composite materials and exploring the application of environmentally friendly materials such as biobased materials; At the same time, the intelligence and automation level of manufacturing processes will be further improved to enhance production efficiency and product quality. In addition, with the integration of technologies such as the Internet of Things and big data, remote monitoring and intelligent diagnosis of ultra wear-resistant acid fracturing hoses will become possible, providing stronger support for the efficient and safe development of oil and gas fields. In summary, as an important equipment in oil and gas exploration and development, the technological development and innovation of ultra wear-resistant acid fracturing hoses are of great significance for improving operational efficiency, reducing costs, and ensuring safety. In the future, with the continuous advancement of technology and the expansion of application fields, ultra wear-resistant acid fracturing hoses will surely usher in a broader development prospect.
