    Different types of casing pipe used in oil extraction: Surface oil casing protects the well from being contaminated by shallow water and shallow gas layers, supports wellhead equipment and maintains the weight of other layers of casing. The technical oil casing separates the pressure at different levels so that the drilling fluid can flow properly and protect the production casing. In order to install anti-burst devices, leak-proof devices and tail pipes in the drilling. Reservoir oil casings direct oil and gas from reservoirs below the surface. It is used to protect drilling and to layer drilling mud. When producing oil casing, the outer diameter is usually 114.3 mm to 508 mm.     Protect wells from contamination from shallow water and shallow gas layers, support wellhead equipment and maintain the weight of other layers of casing.     The technical oil casing separates the pressure at different levels so that the drilling fluid can flow properly a...

    Hydrostatic pressure test is an indispensable link in the manufacturing process of steel pipes, and its role is to detect the anti-leak function of steel pipes under the standard test pressure and time constant. It is the same as the flaw detection process such as radiography and ultrasonic, which is an important means to check the overall quality of steel pipes. What are the requirements for hydrostatic test of petroleum casing pipe?     1. The hydrostatic test pressure value of the pipe with coupling and threaded pipe is the lowest value of the hydrostatic test pressure of the flat-end pipe, the maximum hydrostatic test pressure of the coupling, and the internal pressure leakage resistance, but the standard maximum pressure is 69MPa and the calculated pressure The value is usually rounded to the nearest 0.5 MPa.     2. According to API requirements, the hydrostatic test pressure measuring device should be calibrated within 4 months before each use...

    After the production of the casing pipe and the pipeline, the surface is generally sprayed with anti-rust paint, and the outer surface of the pipe is sprayed with a prominent logo according to the API standard requirements, indicating the manufacturer of the product, the ISO certificate number of the manufacturer, API logo, API Certificate number, nominal diameter, nominal weight, steel grade, length, forming method, hydraulic pressure, furnace number, batch number, tube number and identification of special requirements of customers, such as shipping marks. The thread of the oil casing shall be protected by special thread anti-rust grease.     Each pipe must be capped with steel and plastic at both ends to protect the wire buckle or chamfer.     For petroleum special pipes are usually packed in steel bands, and the weight of each bundle is preferably not more than 2.5 tons, which is convenient for loading and unloading. A waterproof label is usually...

Casing Pipe : Common Uses and Applications Casing pipe is a type of steel pipe that is typically used to enclose and surround a carrier pipe, which is installed through the center of this pipe. Steel casing pipe is most often used in underground construction projects to encase or protect utility lines from being damaged. This pipe can be used when boring horizontally or directionally under roads, rivers, lakes, or railroads. In general, steel casing pipe is extremely durable and versatile, and therefore, it can be used in a variety of construction projects as well.Casing Pipe is available in a complete variety of different sizes and diameters as well as in straight seam, spiral-weld, and rolled and welded types of manufacture. Uses for Casing Pipe Casing pipe is most often used for underground boring to encase and protect pipe. During horizontal underground boring projects under streets, highways, railroads, rivers, and streams, steel casing pipe can be jacked in segments into ...

　　In order to strengthen the borehole wall and ensure continued safe drilling, seal off the oil, gas and water layers, ensure layered testing during exploration and reasonable oil and gas production during the entire mining process, and insert high-strength steel into the drilled well. The process of quality casing and filling cement in the annular space of the wellbore and casing pipe is called cementing operation. 　　Cementing is a key link in the construction of oil and gas wells. Compared with other drilling processes, cementing operations are obviously special. It is a one-time operation. If the quality is not good, it is difficult to remedy under normal circumstances. It is a concealed operation. The main process is downhole and cannot be directly observed during construction. The quality is often determined by the accuracy of the design and the quality of the preparation work. It is also affected by the combination of multiple factors and also affects the subsequent projects; ...

　　The casing pipe is a large-diameter pipe that acts as a fixed oil and gas well wall or wellbore. The casing is inserted into the wellbore and fixed with cement to prevent the wellbore from separating the formation and the wellbore from collapsing, and to ensure that the drilling mud circulates for drilling.Different types of casing used in oil extraction: 　　The surface oil casing is to protect the well from being contaminated by shallow water and shallow gas layers, supporting the piercing equipment and maintaining other layers of the casing. 　　The technical oil casing is to separate the pressures at different levels so that the drilling fluid can flow normally and protect the production casing to install the anti-burst device, the leakage prevention device and the tail pipe in the drilling. 　　The oil layer oil casing mainly exports oil and natural gas from the subsurface storage layer, protects the well with the liver, and stratifies the drilling mud. When producing oil casing...

For the water injection wells that have been newly put into operation, adopt an annulus protection liquid based on dosing and sterilization, and form a system to regularly add; 　　3. In view of the acceleration of the corrosion of the oil casing pipe by mechanical abrasion, it is recommended to add a rubber ring to the oil pipe coupling or ...

　　Steel pipes without joints on the outer surface are made of a single piece of metal and are called seamless steel pipes. According to the manufacturing method, the seamless pipe is divided into a hot rolled pipe, a cold rolled pipe, a cold drawn pipe, an extruded pipe, a top pipe, and the like. According to the shape of the section, seamless steel pipes are divided into two types: circular and special shapes. 　　Shaped tubes have a variety of complex shapes such as squares, ovals, triangles, hexagons, melons, stars and wing tubes. The maximum diameter is 650mm and the minimum diameter is 0.3mm. Depending on the application, there are thick walled tubes and thin walled tubes. Seamless steel pipes are mainly used in petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, casing pipes, automobiles, tractors, and high-precision structural steel pipes for aviation. 　　Classification: Seamless steel pipes along the perimeter of their cross section. According to d...
