Drill Steel Tube Stc Ltc Btc N80 J55 54.5 Lb/FT R1 R2 R3 Seamless Casing Oil Pipe
Product Description:
The oil casing is a steel tube used to support the well wall of oil and gas Wells to ensure the normal operation of the whole well during the drilling process and after completion.  Several layers of casing are used for each well, depending on the drilling depth and geology.  Cement is used for cementing after casing well. Unlike tubing and drill pipe, cement can not be reused and belongs to disposable consumption material.  As a result, casing consumption accounts for more than 70% of all well tubing.  

Casing can be divided into: conduit, surface casing, technical casing and reservoir casing.  
 

Special petroleum pipe is mainly used for drilling oil and gas Wells and oil and gas transportation It includes oil drilling pipe, oil casing, extraction pipe The oil drill pipe is used to connect the drill collar to the drill bit and transfer drilling power.  The oil casing is mainly used to support the well wall during drilling and after completion to ensure the drilling process and the normal operation of the whole oil well after completion.  The suction pipe mainly conveys oil and gas from the bottom of the well to the surface.  

The oil casing is the lifeline to maintain the operation of oil well.  Due to the different geological conditions, the downhole stress state is complex, and the comprehensive effect of tension, pressure, bending and torsion stress on the pipe body has put forward a higher demand on the quality of the casing itself.  If the casing itself is damaged for some reason, it can lead to production loss or even abandonment of the entire well.  
 

According to the strength of steel itself, casing can be divided into different steel grades, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc.  Well conditions, different depths, the use of steel grade is also different.  In corrosive environment, the casing itself is required to have corrosion resistance.  In the complex geological conditions, it is also required that the casing has anti-collapse performance.  
 

The pipe is inserted into the hole and fixed with cement to help separate the wellbore from rock formations and prevent collapse, while also allowing drilling mud to circulate to facilitate drilling.  Casing end processing type: short round thread, long round thread, partial trapezoidal thread, special buckle, etc.  It is mainly used to support the well wall during drilling and after completion to ensure the drilling process and the normal operation of the whole well after completion.  Different types of casing used in oil extraction: The surface casing protects the well from shallow water and gas, supports the wellhead equipment, and maintains the weight of other layers of the casing.  The technical casing separates the pressures at different levels to allow the flow of drilling fluid and protect the production casing.  In order to install blowout preventers, leak preventers and liner in the well.  Oil reservoir The oil casing extracts oil and gas from reservoirs below the surface.  Used to protect drilling and to layer drilling mud.  Casing sizes range from 114.3 mm to 508 mm.  


Protects the well from shallow water and gas contamination, supports the wellhead equipment and maintains the weight of other layers of the casing: 
The technical casing separates the pressures at different levels to allow the flow of drilling fluid and protect the production casing.  In order to install blowout preventers, leak preventers and liner in the well.  

Reservoir Casing - To drain oil and gas from reservoirs below the surface.  Used to protect drilling and to layer drilling mud.  Casing sizes range from 114.3 mm to 508 mm.  

The types and packing of petroleum casing are divided into short thread casing and its coupling and long thread casing and its coupling according to SY/T6194-96" petroleum casing ".  

 

Drill pipe is a type of steel pipe with screw bars at the end that is used to connect the rig's surface equipment to the drilling and grinding equipment or bottom hole unit located at the bottom of the drill.  The drill pipe is used to transport drilling mud to the drill bit, and with the drill bit to raise, lower, or rotate the bottom hole device.  Drill pipe must be able to withstand tremendous internal and external pressure, distortion, bending and vibration.  Drill pipe can be used multiple times during oil and gas extraction and refining.  

The light pipe and raw steel pipe are made into drill pipe after several processing steps.  First, through the processing of steel pipe thickening process, the surface of the light pipe is inward bent, and the steel pipe wall is thickened.  Next, threads are threaded and copper plated to increase strength.  This is followed by a non-destructive quality control inspection followed by welding of the pipe body joint.  The tube is then subjected to welding heat treatment and welding final treatment to eliminate welding residual pressure.  Other tests, including hardness tests, pressure tests and non-destructive tests, should be carried out on finished pipe before finished pipe is painted and packaged.  

The length of drill pipe is usually about nine meters.

Casing Pipe Manufacturing Process:
Steel ingot heating → hydraulic punching → reheating → extension → periodic rolling → reheating → sizing → cooling → straightening → pipe cutting → inspection
1. An annular heating furnace is required for ingot heating;
2. Punching and reheating with hydraulic press;
3. The oil casing plant uses a two-roller guide plate extension machine for extension;
4. Re-use a disc heating furnace for periodic rolling, and use a non-entry furnace for reheating, cooling, straightening, pipe cutting, and inspection.
