Background
In recent years, as the national demand for petroleum and natural gas is increasing, the exploitation of shale gas is also a current hot spot and is also a challenge. Because during the drilling process, the drilling pressure applied to the drill bit is unstable due to the fact that the driller is not timely or the driller is too fast due to driller technology and experience problems or due to the problem of well wall friction, the rock breaking efficiency is affected, and even the drilling speed is possibly affected due to the fact that the drill bit, the cutting teeth of the broken drill bit and the like are damaged due to the fact that the drilling pressure is suddenly increased. On the other hand, PDC bits often do not have enough torque to break rock when drilling hard or abrasive formations, thereby creating a stuck bit, and release of torque from the drill rod downhole results in bit failure. The rock of the deep stratum of the oil field is hard and has high grinding extremum, the conventional roller bit is used for drilling, the single bit has small footage, multiple tripping is needed, and the mechanical drilling speed is low; when the screw is used for compound drilling, the service life of the screw is low and the use effect is not ideal due to higher temperature in a deep well; meanwhile, stick-slip vibration is frequently generated in the deep well drilling process, so that the drilling tool is easy to fail due to the stick-slip vibration, and the mechanical drilling speed is reduced. In addition, the mechanical drilling speed can be improved to a greater extent by adopting the gas drilling technology, but the underground complex situation is easy to occur under the condition of stratum water outlet, and the gas drilling supporting equipment is more, so that the cost is relatively high.
