Product Application
PDC drilling drag bit is made by PDC cutters and steel. It is one of the steel body PDC bit and belong to non core diamond pdc bit. Having the feature of long service life and wear resistance. Widely used in coal mining and water well drilling.
The bit of water well drilling rig will inevitably slip during production.
When the bit slips, it is necessary to deal with and punish it in time to guard against problems affecting the production efficiency and production style of water well drilling rig.
If the water well drilling rig has slip signs, the punishment can be handled briefly. After the second tripping, it is necessary to determine the thickness of the residue soil lost by the data on the display, and then check the soft hardness of the geology lost by the data. If there is a lot of soil lost by the data, and it is hard mastic, it is necessary to change a smaller bit to deal with the problem of slip punishment, This tension is due to the large gap between the small-diameter drill bucket and the hole wall. Under the action of the weight and pressure of the drill pipe drill bucket, it is decided that the gap between the drill bucket and the hole wall will be squeezed to the left and right.
When soft mud is lost on the well drilling rig, there is no need to change the drilling bucket, reuse the pressurization and reverse the forward rotation of the power head. Because there is a certain gap between the power head and the drill pipe, there is a gap between each section of drill pipe. Although the drill bit will slip during the drilling time, due to the resistance of the weight of the drill pipe and the drill bucket, it is necessary to quickly reverse the forward rotation of the drill pipe, The use of clearance can breed and produce strong striking force.
