Abstract
The invention discloses a stable drill pipe. The stable drill pipe comprises a pipe body and stabilization blocks fixedly installed on the outer cylindrical face of the pipe body. A discharging channel is formed between every two adjacent stabilization blocks. The stabilization blocks are polygonal arc-shaped plates. On the outer cylindrical surface of the pipe body, the inner arc faces of the polygonal arc-shaped plates are fixedly connected with the outer cylindrical surface of the pipe body. The stable drill pipe is suitable for different rotation speeds under different geological conditions and can guarantee that rock residues can be smoothly carried to the ground in flushing fluid and avoid that when slurry leaks suddenly in a shaft, a wedging accident occurs.
Description
Technical field
The present invention relates to mine engineering mechanical field, particularly one stablizes drilling rod.
Background technology
In the packed hole drilling processes such as anti-well guide hole, flushing fluid can rise to ground with the rock slag of fragmentation from the space between stable drilling rod wing plate, and stablize the key factor that the validity of drilling rod to wall of hole is bottom hole assemblies validity in this course, be affect one of hole scattering direct factor.Drilling rod is stablized for common straight wing plate, spiral is stablized drilling rod and is stablized drilling rod (it is similar that drilling rod stablized by its hold angle effect and straight wing plate) with roller, stablize the turning effort of drilling rod at straight wing plate under, mud helically rises with rock slag, and rock slag is easily squeezed in the gap outside stable drilling rod and between the borehole wall in the process that rock slag rises, wing plate is caused to wear and tear very fast, even asphyxia by external pressure on the chest and abdomen stablizes drilling rod, cause and embrace brill accident, and traditional spiral is stablized drilling rod rock the slag rate of climb and drilling tool rotary rotary speed between spiral wing plate must be made to match, rock slag straight line in annular space just can be made to increase, but drilling geology inclement condition, rotating speed can change at any time with geological conditions, in drilling process, the rising of rock slag just makes moderate progress relative to straight wing plate, still easily occur that asphyxia by external pressure on the chest and abdomen stablizes drilling rod, occur embracing brill accident.When there is unexpected spillage in pit shaft, the rock slag in mud is stablized drilling rod place at spiral and is very easily caused card, embraces brill accident.
