AZM Oilfield Offers a full range of OCTG items including Casing, Tubing, Drill Pipe, Drill Collar, and Drill bits.
OCTG Items (Oil Country Tubular Goods) are an essential component of the oil and gas industry, serving a critical role in exploration, drilling, and production processes. As a reputable provider of oilfield solutions, AZM Oilfield Technologies offers a comprehensive range of OCTG items to meet the diverse needs of our clients.
A casing is a large-diameter pipe that is installed in oil and gas wells to provide structural integrity and support the wellbore. It protects the well from external forces and prevents the collapse of the hole. Our casing products are manufactured with precision and adhere to stringent quality standards, ensuring optimal performance and durability in the most challenging environments.
Tubing is a smaller diameter pipe inserted into the casing to enable the flow of oil or gas from the reservoir to the surface. It is crucial for efficient production and reservoir management. AZM Oilfield Technologies offers a range of tubing solutions that are resistant to corrosion and abrasion, ensuring smooth and uninterrupted production operations.
Drill pipe is hollow, thin-walled, steel or aluminum alloy piping that is used on drilling rigs, it is hollow to allow drilling fluid to be pumped down the hole through the bit and back up through the annulus. It comes in a variety of sizes, strengths, and wall thicknesses, It is typically 27-32 feet in length(Range 2), Longer range in R3 up to 45 feet are also offered.
Drill collars are hollow, thick walled pipe with smaller nozzle, Per Unit Length of the drill collar is typically 4-5 times weight of the drill pipe. Drill collar are offered in all kinds, Round drill collar, spiral drill collar, non magnetic drill collar, square drill collar etc. We offer Drill collar in all variety of conventional and premium thread. Drill collars are available in R2 & R3 length
Mechanical Properties: < 7inch Drill collar Yield Strength ≥ 758 Mpa, Tensile Strength ≥ 965 Mpa, Four Time Elongation ≥ 13%, Impact Energy Ak ≥ 54J, (Single impact work ≥ 47 J, Average ≥ 54J),Hardness range 285 HB-341 HB
≥ 7inch Drill collar Yield Strength ≥689 Mpa, Tensile Strength ≥ 931 Mpa, Four Time Elongation ≥ 13%, Impact Energy Ak ≥ 54J, (Single impact work ≥ 47 J, Average ≥ 54J),Hardness range 285 HB-341 HB
Heavy weight Drill pipe is a medium weight drilling tool similar to drill pipe , whose wall thickness is more than the drill pipe but thinner than drill collar, Its tube is connected with drill pipe joint (Integral heavy weight drill pipe is made up of drill pipe and tool joint).
During assembly, it is inserted between drill pipe and drill collar to prevent sudden changes in cross section of drill string and reduces fatigue. Using Heavy weight Drill Pipe to replace part of the drill collar can reduce torque, improve load, and increase drill ability during deep well drilling.
It is easy to operate and can save tripping time. It can drill in high speed under low torque in directional wells and reduces abrasion and fracture of string without differential pressure and sticking because of use of lower grade of steel than drill collar.
