4,borehole drilling equipment the cylinder pressurized, if the geological hard need to slow pressure, continuous excessive pressure, will make the oil tank oil or bending. 5,borehole drilling equipment often check the drill pipe outside the mouth of the wire rope screws, if loose, to both the top and below the screws, otherwise it will cause
Meanwhile, the collision of drill pipe to the borehole is also intensified. The larger the weight on bit, the more serious the borehole collapse because of the combined action of drilling fluid erosion and drill pipe collision to the borehole. The results are proved by the macroscopic observation images (Figure 23) and SEM image (Figure 24).
