Drilling hose assembly is a key component used in the drilling industry. Its classification, usage, implementation standards, technical parameters and usage precautions are as follows:
1. Classification of drilling hose assemblies
The drilling hose assembly is mainly composed of hoses and joints. According to its structure and usage characteristics, it can be divided into the following categories:
1. Steel wire wound drilling hose assembly: This kind of hose is mainly made of steel wire wound around the outside of the hose. It has the characteristics of high strength, high wear resistance and high pressure resistance. It is often used in deep hole drilling and high pressure drilling.
2. Braided drilling hose assembly: This kind of hose is mainly made of braided material. It is light, soft and resistant to bending. It is suitable for shallow hole drilling and drilling in areas with complex terrain.
3. Cloth-clip drilling hose assembly: This kind of hose is mainly made of cloth-clip material, has medium strength and wear resistance, and is suitable for medium and shallow hole drilling.
4. Bag pressure drilling hose assembly: This kind of hose is mainly made of rubber material. It has the characteristics of good sealing and high pressure resistance. It is suitable for drilling occasions with high high pressure sealing requirements.
2. Purpose of drilling hose assembly
Drilling hose assemblies are widely used in the drilling industry. Its main uses include:
1. Transport high-pressure liquid: The drilling hose assembly can be used to transport high-pressure liquid, such as mud, foam, etc., to assist the drill bit in drilling.
2. Connecting equipment: The drilling hose assembly can be used to connect drilling equipment and tools, such as drilling rigs, water pumps, winches, etc., to achieve effective operation of the equipment.
3. Sealing and protection: The drilling hose assembly can be used to seal and protect equipment connections to prevent impurities such as high-pressure liquid and dust from entering the inside of the equipment, thereby improving the reliability and service life of the equipment.
3. Execution standards for drilling hose assemblies
The drilling hose assembly should comply with the requirements of relevant national standards and specifications. The main standards include:
1. GB/T 2550-2008 "Rubber hoses and hose assemblies for petroleum products and natural gas applications". This standard specifies the materials, structure, dimensions and technical requirements of drilling hose assemblies.
2. API SPEC 17J "Specification for Drilling and Workover Equipment". This specification mainly stipulates the use conditions, test methods, inspection rules, etc. of drilling hose assemblies.
3. API SPEC 17K "Specification for Ground and Underground Pipe Laying Equipment". This specification stipulates the materials, structure, dimensions, test methods and inspection rules of drilling hose assemblies.
4. Technical parameters of drilling hose assembly
The main technical parameters of the drilling hose assembly include:
1. Inner diameter size: The inner diameter size directly affects the flow rate and pressure of the transported liquid, so the appropriate inner diameter size needs to be selected according to actual needs.
2. Outer diameter size: The outer diameter size affects the stiffness and pressure resistance of the hose, so the appropriate outer diameter size needs to be selected according to actual needs.
3. Length dimension: The length dimension should take into account the installation and use needs of the equipment, as well as the convenience of transportation and storage.
4. Pressure resistance: Pressure resistance is one of the important indicators to measure the performance of the drilling hose assembly, and it needs to meet the pressure requirements in actual use.
5. Wear resistance: Wear resistance is also one of the important indicators to measure the performance of drilling hose assembly, and it needs to meet the wear resistance requirements in actual use.
6. High temperature resistance: When used in certain high temperature environments, the drilling hose assembly needs to have high temperature resistance to ensure its reliability and service life.
7. Low temperature resistance: When used in certain low temperature environments, the drilling hose assembly needs to have low temperature resistance to ensure its softness and flexibility.
