API Oil Casing American Standard Oil Casing Manufacturer

Oil Casing Is Mainly Used For Transporting Liquids And Gases Such As Oil, Natural Gas, Coal Gas, Water, Etc. The Main Application Countries Of This Product Are Concentrated In The Middle East, Europe, And The United States. According To The API 5CT Standard, Petroleum Casing Can Be Divided Into Three Specifications Based On Length: R-1, R-2, And R-3. The Main Materials Include J55, K55, N80, L80, P110, Etc. Pipelines Made Of Petroleum Casing Materials Have Unique Natural Advantages In Extreme High Temperature And High Pressure Environments. API 5CT Petroleum Casing Requires Various Tests And Inspections, Such As Flattening Test, Tensile Test, Impact Test, Tensile Test, Etc., From Raw Materials To Finished Products Before Leaving The Factory.

Casing Is A Large-diameter Pipe Material Used To Stabilize The Wellbore Or Wellbore Of Oil And Gas Wells. It Is Inserted Into The Wellbore And Fixed With Cement To Isolate Rock Formations, Prevent Wellbore Collapse, And Ensure The Circulation Of Drilling Mud For Exploration And Exploitation. The Different Types Of Casing Used In The Process Of Oil Extraction Include:

Surface Casing

• Protect Drilling From Pollution In Shallow Water And Gas Layers

• Support Wellhead Equipment And Bear The Weight Of Other Casing Layers

Technical Casing

• Isolate Pressure From Different Layers To Ensure Normal Circulation Of Drilling Fluid And Protect Production Casing

• Easy To Install Explosion-proof Devices, Leak Proof Devices, And Tailpipes Inside The Wellbore

Production Casing

• Transporting Oil And Natural Gas From Underground Reservoirs To The Surface

• Protect The Wellbore And Isolate The Drilling Mud Layer

The Outer Diameter Of Oil Casing During Production Is Usually Between 114.3 Millimeters And 508 Millimeters.

Development Of Chinese Petroleum Casing:
After Nearly 20 Years Of Effort, China's Oil Casing Production Has Grown From Scratch, From Low Prices To High Prices, From Low Steel Grades To API Series Products, And Even To Non API Products With Special Requirements. Both In Terms Of Quantity And Quality, It Has Almost Reached The Level Of Foreign Oil Casings. The Market Share Of Domestic Oil Well Tubing Has Exceeded 80%, And The Products Have Been Net Exported For Many Years.

In 2011, China's Crude Oil Production Reached 204 Million Tons, A Year-on-year Increase Of 0.32%; The Natural Gas Production Reached 102.531 Billion Cubic Meters, A Year-on-year Increase Of 6.9%, Reaching A Historic High. China Is Still In The Stage Of Rapid Urbanization And Industrialization, And It Is Expected That Oil Demand Will Grow At An Average Annual Rate Of Around 4% In The Coming Years. The Continuous Increase In Oil Demand Has Driven The Rise In Demand For Oil Drilling And Production Equipment In China.

From A Domestic Regional Perspective, The Demand For Oil Casing Is No Longer Solely Concentrated In The Eastern Region. The Trend Of Domestic Oil And Gas Field Development Has Shifted From Initially Developing Eastern Oil Fields Such As Daqing, Liaohe, And Shengli, To Later Expanding To Western Oil Fields Such As Sichuan And Xinjiang. Offshore Oil Fields Are Also Receiving Increasing Attention. And Development Is Going From Land To Mudflat, From Shallow Sea To Deep Sea. With The Increase Of Drilling Depth And The Complexity Of Working Conditions, The Requirements For Oil Casing Will Inevitably Become Higher And Higher.
