Drill Rod. The drill rod, also called drilling string and drill pipe, is a kind of machine whose end has steel pipe with threads, and is typically used to connect drilling rig surface equipment with drilling grinding equipment or bottom hole unit at the drilling bottom
During drilling operations, a pipe is considered stuck if it cannot be freed and pulled out of the hole without damaging the pipe and without exceeding the drilling rig ' s maximum allowed hook load. Differential pressure pipe sticking and mechanical pipe sticking are addressed in this section. DifferentialPressure Pipe Sticking
A pipe upsetting treatment is employed for the pipe body to ensure that the outer diameter of thickened end, the joint outer diameter, and the outer diameter of pipe is the same. Drilling Stabilizer Drilling stabilizer is an important tool for preventing well deviation in the drilling projects of petroleum, natural gas, and geological ...

Drill pipe is made from geological drilling through hot rolling and cold drawing. Drill tube is mainly used in drilling rigs to facilitate the drilling of a well bore that comes in a variety of sizes, strengths and weights. But length is typically 27 to 32 feet. The longer lengths are up to 45 feet.

Measurement while drilling technology has become an important tool for reservoir evaluation in the past 10 years. Gamma ray, resistivity, and porosity logs obtained during drilling are commonly being used to supplement or replace wireline logs for formation evaluation and geological correlation in high risk or high cost operations.
drill pipe and up the annulus. When drilling with mists or air, the mud tank or pit is replaced by a cyclonetype separator. Air or mist drilling provides good formation sampling and can give reasonable estimates of geothermal fluid production. Other Types of Rotary Drilling Downhole Hammer One of the more popular methods for drilling
Drill pipe . Drill pipe is used for core drilling for geological department, which is a kind of hollow cross section, no seams around the long bar of steel. Steel hollow sections with a large pipe for transporting fluids, such as the transportation of oil, gas, coal gas, water and some solid materials, pipes, etc..
And the drill pipe should be pulled out when the time is more than 8 hours. drilling process, choose the appropriate bit pressure and drilling speed to feed evenly according to the geological conditions. When drilling in places where the geology is not uniform or where the rock strata meet, the drill pressure and speed should be reduced ...
Wellbore trajectory is controlled by the type of bottom hole assembly used and the weight on the bit. The bottom hole assembly, or BHA, is that portion of the drill string closest to the drill consists of several components: Heavyweight drill pipe, which has the same outer diameter as regular drill pipe but with thicker walls for greater weight, used as a transition between drill ...
Drilling a well requires a drill bit that eats its way through the earth's crust and long pipes (drill string), linking the drill bit to the surface. The drill pipe is gradually fed into the well by the drilling rig. Nowadays, the rotary drilling technique is used to sink virtually all wells.
Each oil well would need several layers of casings according to different drilling depth and geological conditions. J55 oil well casing pipe is an important tool used in oil drilling. It has excellent elongation property. After the pipe is in the well, the well is then be cemented. Unlike oil pipe and drill rod, casing tube is not reusable.
