Oil drilling and production hose: a key equipment in oil exploration Oil drilling and production hoses play a crucial role in the complex environment of oil exploration and extraction. These hoses not only need to maintain stability and reliability under extreme conditions, but also withstand the challenges of high pressure, high temperature, and corrosive fluids. This article will delve into the technical characteristics of oil drilling and production hoses and their key role in oil exploration. 1、 Structure of oil drilling and production hoses Oil drilling and production hoses are usually composed of multiple layers, including an inner rubber layer, a reinforcement layer, and an outer rubber layer. This multi-layer design ensures the stability and durability of the hose under various working conditions. Inner rubber layer: usually made of materials that are resistant to oil, high temperature, and corrosion, such as polyurethane or nitrile rubber. These materials can withstand the erosion of corrosive fluids such as oil and natural gas while maintaining their elasticity and sealing properties. Reinforcement layer: It is the core part of the hose, usually made of high-strength, high modulus synthetic fibers or steel wires. The reinforcement layer provides the required pressure resistance and tensile strength for the hose, ensuring that it will not rupture or deform under high pressure and high flow working conditions. Outer adhesive layer: usually made of weather resistant materials such as polyvinyl chloride or polyethylene. The outer adhesive layer not only protects the internal structure of the hose from external environmental erosion, but also enhances the durability and wear resistance of the hose. 2、 The key role of oil drilling and production hoses Oil drilling and production hoses play various key roles in oil exploration, including but not limited to the following aspects: Fluid transmission: Oil drilling and production hoses are the main channels for fluid transmission in oil exploration. They are used to transport fluids such as drilling fluid, mud, oil, and natural gas from underground to the surface, or from the surface to underground. The transport of these fluids is crucial for maintaining the stability and efficiency of drilling operations. Pressure control: In oil exploration, pressure control is crucial. Oil drilling and production hoses can withstand the impact of high-pressure fluids and maintain stable fluid flow through their structural design and material selection. This helps prevent dangerous situations such as blowouts and leaks, ensuring the safe conduct of drilling operations. Corrosion protection: Fluids such as oil and natural gas often contain corrosive substances that can cause damage to pipelines and equipment. The inner and outer rubber layers of oil drilling and production hoses are made of corrosion-resistant materials, which can effectively resist the erosion of these corrosive substances and extend the service life of the hoses. Flexibility and adaptability: Oil drilling and production hoses have good flexibility and adaptability, and can adapt to various complex geological conditions and drilling processes. They can maintain stable performance under bending, twisting, stretching, and other conditions, ensuring the smooth progress of drilling operations. 3、 Application scenarios of oil drilling and production hoses Oil drilling and production hoses are suitable for various scenarios of oil exploration and extraction, including but not limited to: Oil drilling: Oil drilling and production hoses are suitable for flexible connections between the top of drilling risers and vertically movable faucets during the oil drilling process, used in mud conveying systems. Mud transportation: Petroleum drilling and production hoses are suitable for pipelines between drilling risers and pump pipes, used to adjust installation errors, achieve connection and vibration isolation, and can also be applied to rotary drilling rig pumps. High pressure transportation: Petroleum drilling and production hoses can withstand water-based or oil-based mud with a minimum aniline point of 66 ℃ under high-pressure transportation conditions, and can prevent hydrogen gas from corroding sulfides. They are suitable for transporting water, oil, mud and other media during downhole operations in oil fields. 4、 Hydraulic hoses and drilling hoses In addition to oil drilling and production hoses, hydraulic hoses and drilling hoses also play an important role in oil exploration and extraction. Hydraulic hose: Hydraulic hose is a flexible pipeline used to transport hydraulic media in transmission devices, widely used in mining, military, engineering machinery, metallurgy, petroleum, chemical, aviation, and navigation fields. The working environment of high-pressure hydraulic hoses is harsh, with high requirements for materials, processes, and equipment, making them a high-end product among rubber hoses. Drilling hose: Drilling hose, also known as rubber hose for rotary drilling and shock absorption, is used for oilfield cementing, well repair, and petroleum geological exploration. The drilling rubber hose consists of multiple layers of structure, including an inner rubber layer, an inner rubber protective layer, a middle rubber layer, a steel wire winding layer, and an outer rubber layer, suitable for high-pressure mud transportation and shock absorption connection.
