Description
Casing Pipes
Description:
Casing pipes are large-diameter steel pipes designed to provide structural integrity as the outermost layer of oil and gas wells, or wellbores. They are inserted into the wellbore and cemented in place to prevent collapse, protect subsurface formations, and facilitate the circulation of drilling fluids for extraction operations. Steel casing pipes feature smooth walls and a minimum yield strength of 35,000 psi, ensuring robust performance in demanding oilfield environments.
Well Casing Function:
Well casing serves as the sidewall of the well, maintaining the integrity of the borehole throughout the drilling and production processes.
Standards and Technical Specifications:
API Spec 5CT and ISO 13680 standards govern the manufacturing and quality requirements.
Grade: J55, K55, N80-1, N80-Q, L80-1, L80-9Cr, L80-13Cr, C95, P110.
Thread Types: NUE (Non-Upset End), EUE (External Upset End), VAM, STC (Short Thread Coupling), LTC (Long Thread Coupling), BTC (Buttress Thread Coupling), special clearance, XC, VAM TOP, NEW VAM.
Oil Casing Pipe:
Oil casings are essential for maintaining the integrity of the well wall and downhole operations. They are categorized into conductor casings, technical casings, and oil casings based on their specific diameters and operational requirements.
Dimensions:
Outer Diameter (OD): 114.3mm - 508mm
Wall Thickness (WT): 5.21mm - 16.13mm
Summary
Casing pipes play a vital role in the oil and gas industry by ensuring the stability and protection of wellbores during drilling, completion, and production phases. Designed to withstand high pressures and harsh conditions, they adhere to stringent API and ISO standards, offering durability and reliability for critical oilfield operations.
