With the continuous development of oil and natural gas extraction, well completion operations are an important part of the entire extraction process, and their technical level and safety performance requirements are becoming higher and higher. Especially in high-pressure environments, well completion operations face huge challenges. In order to ensure the efficiency, safety and reliability of well completion operations, a hose that can adapt to high-pressure environments and transport multiple fracturing fluids at the same time has become an indispensable and important equipment. This article was published by Letone Hydraulic Technology Co., Ltd. on May 5, 2024. It will focus on the application scope and technical characteristics of this hose. Please correct me if there are any errors.
First, let’s take a look at the application range of frac hoses. It is mainly used in processes such as acid fracturing, sand fracturing, and hydraulic fracturing pipelines in well completion operations. In these processes, various fracturing fluids need to be transported under high pressure, such as water-based, oil-based, foam, acid-based, etc. This kind of hose has excellent high pressure resistance and can withstand extremely high pressure, ensuring the stability and safety of the transportation process.
Secondly, let’s discuss the technical characteristics of fracturing hoses. Its inner layer is made of UPE material, which has excellent corrosion resistance and wear resistance, and can effectively prevent fracturing fluid from eroding and wearing the inner layer during transportation. At the same time, the reinforcement layer uses 4-6 layers of high-strength and super-flexible steel wires or steel wire ropes. This structure not only enhances the pressure resistance of the hose, but also ensures the flexibility and durability of the hose. The outer layer is made of wear-resistant and weather-resistant synthetic rubber, which can resist the impact of the external environment on the hose and extend its service life.
In addition, the
fracturing hose also has high temperature adaptability and can work normally in the temperature range of -20°C to +82°C. This feature enables the hose to adapt to climatic conditions in different regions and seasons, ensuring the continuity and stability of completion operations.
During well completion operations, hose safety is critical. Therefore, the acid fracturing hose strictly follows API Spec. 7K FSL0 and ABS and other implementation standards during the design and manufacturing process, ensuring the quality and reliability of the hose. At the same time, the hose is also equipped with connectors such as hammer unions or flanges, which further improves the safety and pressure transmission efficiency of the hose manifold, reduces the frequency of replacement, and effectively solves the problems encountered in traditional hard pipe fracturing operations. It has shortcomings such as high single-well fracturing costs and low operating efficiency.
In practical applications,
acidified fracturing hoses have demonstrated excellent performance and results. Compared with traditional steel pipes, the use of fracturing hoses can save 70% of costs, and the installation efficiency is doubled. This advantage plays an important leading role in the scale-effective development of global unconventional oil and gas resources.
