Flexible Fracturing Hoses Reshape the New Ecosystem of Efficient Fracturing Operations

       In the field of oil and gas resourcedevelopment, especially in the extraction of unconventional oil and gas, fracturingtechnology is

 a key means to unlock underground resources. Amid the severechallenges of high pressure, high temperature, and high abrasion, fracturinghoses—acting as the "flexible arteries"connecting surface pump units to underground reservoirs—are reshaping traditional operation models with their unique advantages.They have become the "new favorite" for the efficient development ofunconventional oil and gas such as shale gas and shale oil.

From "Steel Behemoths" to "FlexibleSpirits":An Inevitable Choice for Technological Iteration

       Hydraulic fracturing technology is one ofthe essential technologies for achieving economic production capacity ofunconventional oil and gas such as shale gas and shale oil currently. Itspurpose is to create channels for gas flow in deep rock formations, andparameters including fracture morphology, direction, and seepage capacitydirectly determine the reservoir stimulation effect and final productioncapacity. In this process, the manifold system, which undertakes the task oftransporting high-pressure fracturing fluid, is of crucial importance to itsperformance.In traditional fracturing operations,steel pipelines (rigid pipes) were once the mainstream choice. However, their"rigid" nature has gradually exposed numerous pain points in complexon-site operations:

       1、Prominent safetyhazards: Steel pipe connections require a large number of swivel elbows andflanges. Under long-term exposure to high pressure and erosion by high-velocityfracturing fluid carrying sharp proppants, these connection points are prone toaccidents such as leakage and burst. Studies have indicated that even manifoldsthat passed inspection in accordance with original standards may still develop issuesduring operations.

       2、Low operational efficiency: The installation of heavysteel pipes requires significant manpower and heavy machinery, and theconnection process is cumbersome and time-consuming. A large-scale fracturingoperation may involve connecting hundreds of nodes, making installationlabor-intensive and time-consuming.

       3、High comprehensivecosts: Costs are not only reflected in the labor and time expenses of a singleoperation, but more notably in the high value of components such as elbows, aswell as maintenance and depreciation costs—steel pipesare prone to wear under harsh working conditions and require frequentreplacement.Limited adaptability: In uneven well sites, the layoutof steel pipelines is difficult, and they struggle to flexibly adapt todifferent wellhead layouts and the need for quick connection with fracturingpump trucks.

       4、Limited adaptability: In uneven wellsites, the layout of steel pipelines is difficult, and they struggle toflexibly adapt to different wellhead layouts and the need for quick connectionwith fracturing pump trucks.In addition, traditional testing methods(such as ultrasonic thickness measurement and magnetic particle testing) alsohave limitations in ensuring manifold safety. They often fail to comprehensivelydetect internal damage in components with complex structures, which poseshidden risks to operational safety.

DUPT's Breakthrough: Forging"Flexible Advantages" with Innovative Technology

       Faced with industry pain points and challenges,Deshi Co., Ltd., relying on its technological accumulation and continuousR&D investment, has launched independently developed super wear-resistantacidizing fracturing hoses, providing the industry with a safer, moreefficient, and more economical solution.The hoses adopt a composite structure ofhigh-strength steel wire reinforcement layer and special rubber, which can notonly withstand an extreme pressure of 140MPa but also possess the"shape-adaptive" flexible property. Calculated based on the scale ofzipper operations for 4 wells (construction scale: 20 fracturing trucks,displacement of 18.0 m³/min, constructionpressure limit of 90MPa), if all manifold connections use high-low pressuremanifold skids and high-pressure diversion skids:The number of high-pressure pipe valves andfittings for flexible fracturing hoses is only 1/3 of that of conventionalsteel pipe connections;On-site connection points are reduced byapproximately 70%;Manifold connection time is reduced byapproximately 50%;Compared with conventional steel pipemanifolds, flexible fracturing hoses save on-site equipment costs byapproximately 41.2%.Technological Core: The Leap from"Functional" to "High-Performance"

Technological Core: The Leap from"Functional" to "High-Performance"

       The performance leap of fracturing hoses stems from the dualinnovation of materials science and manufacturing processes:

        1、Corrosion-Resistant "Armor": Foracidizing fracturing scenarios, the hose uses a UPE (Ultra-High MolecularWeight Polyethylene) + HNBR (Hydrogenated Nitrile Butadiene Rubber) lininglayer. This not only resists strong acid and alkali corrosion but also ensuresa service life of no less than 2,000 hours under operating conditions with asand content of 30%.

       2、Intelligent Safety Design: The productintegrates a wear indicator layer—when the inner layeris worn down to the critical threshold, a red indicator layer becomes visible,enabling "visualized" service life management. Additionally, thedual-functional zone joint crimping technology increases the bonding strengthbetween the joint and the hose body by 50%, eliminating the risk of jointdisengagement.

       3、Extreme Environment Adaptability: Thescientific structural design allows the fracturing hose to meet the rigorousrequirements of corrosion resistance and ultra-wear resistance. It also coversthe entire range of application scenarios, from low to high temperatures, andfrom onshore to offshore operations.
