Heavy weight drill pipes are essential in oil and gas exploration, facilitating the drilling of deep wells to access underground reservoirs. High-quality drill pipe for sale transmit drilling fluid, power the drill bit, and withstand extreme pressures and temperatures, ensuring efficient and safe extraction of hydrocarbons from challenging environments.
In geothermal and water well drilling, drill pipes, such as the water well drill pipe for sale, are used to reach underground water sources or geothermal energy reservoirs. Drill pipe from trustworthy drill pipe manufacturers provides the necessary strength and flexibility to drill through various soil and rock formations, ensuring a reliable supply of water or sustainable energy for residential, agricultural, and industrial use.
1. Structural Differences:
Ordinary drill pipe: with thin wall thickness, short joint length, and consistent inner diameter, drill pipe is mainly used to connect the drill and drill bit.
Heavy-weight drill pipe: the wall thickness is increased by 2-3 times, the joint is longer with a wear-resistant pad, and there is an extra-thick section in the middle, which has the function of a stabilizer.
2. Functional Features
Ordinary drill pipe: Transfers torque and transports drilling fluid, suitable for conventional drilling.
Heavy-weight drill pipe:
The heavyweight drill pipe, including WEILIDA's DTH drill pipe for sale, reduces the stress concentration between the drill collar and the drill pipe to prevent fatigue damage.
This drill stem pipe reduces friction and sticking risk in directional/horizontal wells;
The heavyweight drill pipe can replace some drill collars to improve the accuracy of wellbore trajectory control
3. Application Scenarios
Ordinary drill pipe: standard drilling operation.
Heavy weight drill pipe: deep well, directional well, extended reach well and other complex working conditions.
4. Price and Specification
The price of ordinary drill pipe is low, with various specifications;
The price of heavy weight drill pipe is relatively high, which needs to be customized according to the drilling depth, diameter, etc.
