Geological drill pipe refers to a kind of geological alloy pipe through a series of processing procedures such as wire high-temperature quenching. It is mainly connected with drilling rig and drilling tool and plays a role in transmitting drilling rig torque. At the same time, most geological drill pipes are hollow structures and can transport all kinds of mud or flushing fluid. In the geological drilling work, it is one of the most commonly used drilling accessories, in the purchase of gold drill geological drill pipe, should pay attention to the commonly used parameters are mainly material, specifications and length. Geological drill pipe 1, material. According to the different types of drilling operations, there are different requirements for the material of geological drill pipes, and the regular DZ4 is selected for ordinary coalfield drilling tasks.

geological drill pipe
1, material. According to different types of drilling operations, there are different requirements for the material of geological drill pipes. For common coalfield drilling tasks, regular DZ40 or 45# steel can be selected. For diamond drill bits used with rock formations, R780 or DZ50 drill pipes are often used at most in the field of oil drilling.
2, specifications and models. From the diameter range of geological drill pipe, the specifications and models of geological drill pipe mainly include: Φ34mm, Φ42mm, Φ50mm, Φ60mm, Φ63.5mm, Φ73mm, Φ89mm and other 7 common specifications. Geological drilling often use 42mm and 50mm two, in the drilling of large-diameter water wells or oil wells are often used in the larger diameter of the geological drill pipe.
3, the length. In terms of the length of the geological drill pipe, the production length of the geological drill pipe can be customized according to customer needs without affecting the process principles. Among them, the common length is 0.5 meters, 1 meters, 1.5 meters, 2 meters, 2.5 meters, 3 meters, 4 meters and other 7 specifications, of which 1 meter and 1.5 meters are the most commonly used. When drilling deeper holes, in principle, drill pipes of more than 3 meters should be used as much as possible, but if rope drilling tools are used, relatively short drill pipes can be used to facilitate installation and disassembly.
Geological drill pipe is a necessary drilling tool for geological exploration, hydrological survey, coal mine exploration and engineering exploration. The geological drill pipes produced by Yikuang mainly include 42mm and 50mm geological drill pipes made of Baosteel R780, which can better complete the drilling work of water wells with diamond drilling bits.
