Drill Pipe Joint - an overview ScienceDirect Topics

The erosion of the drill pipe joint is severer than that of the drill pipe body, using the small slope of drill pipe joint can reduce the local erosion of drill pipe joint. Comparison of drill pipe erosion in vertical well and drill pipe erosion in horizontal well shows that the peak erosion rate in horizontal well increases by 3.7 times. (3) The increase of drill pipe eccentricity, wellbore enlargement and ROP, the local peak

Horizontal Directional Drilling Article all about pipelines

Horizontal directional drilling (HDD) is a steerable trenchless method of installing underground pipelines in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. Directional boring is used when trenching or excavating is not practical. The tools and techniques used in the HDD process are an outgrowth of the oil well ...

18-04-2021  Heavy weight drill pipe (HWDP) is a tubular pipe that adds weight or acts as a transitional piece in the drill string. As a transitional section of the drill string, it is placed between the drill collar and standard drill pipe to reduce fatigue failures. In other applications the HWDP is used as an additional weight to weigh down the drill string.

Tricone Bit - an overview ScienceDirect Topics

A drill collar is a thick wall pipe that gives weight to the drill bit, allowing the drill bit teeth to cut into the formation rock. Drill collars form a bottomhole assembly, with stabilizers installed at different distances from the bit (Figure 1.9) to control the well trajectory. The number of drill collars in a BHA depends on how much weight must be applied to the bit to make it advance efficiently (Bourgoyne et al., 1991).
