EQUIPMENT

  • Different PDC bits

    The PDC bit is an abbreviation for Polycrystalline Diamond Compact Bit, also known as polycrystalline diamond cutting block or composite bit. Since the introduction of the PDC cutting block by General Electric Company in 1973 and the development of the first PDC bit, the PDC bit has been widely used in oil drilling due to its advantages of fast drilling speed, long life and high footage. Almost all drill manufacturers have adopted this technology to start producing their own PDC bit series.

  • Influence of Drilling Pressure of PDC Bit on Drilling

    Drilling pressure is a condition that must be found in the rock under the well. Its condition ensures the method and characteristics of the broken rock, and the straightness affects the speed of the drilling and the method of its destruction. At the time of construction, the PDC type is subjected to axial pressure and the effect of turning, and it is rubbed, dull and destroyed during pressing and cutting of the stone, which will definitely affect the speed of advancement.      The roller cone bit is the most important parameter in drilling, not only to help show its cut to the rock formation, but also to minimize its friction. After doubling the pressure and checking the PDC type at the different level of drilling, the ending shows that different rocks have different speeds when increasing the pressure.

  • Inspection and precautions before the drill bit enters the well

    Inspection of the cone bit before entering the well (1) Verify that the model has been selected, and the diameter symbol does not meet the demand; (2) The thread and weld seams that have been carefully watched are not in good condition; (3) Check that the nozzle is not firmly fixed, and the water eye should be smooth; make the hand rotate the cone, and its seal should be normal; its pressure compensation procedure should be intact, and the pressure relief hole needs to be blocked. Precautions when drilling a bit into the well (1) The threaded fastener is applied to the threaded oil after the cleaning completion value; (2) choose to use suitable loading and unloading equipment, which can not be banged when it is placed inside; (3) Tightening according to the specified torque when tightening; (4) It is necessary to be stable when performing the drill-down operation, and it is impossible to hard press when it encounters obstacles. The drilling speed in the insert type should be slow to prevent damage in the hard ground and the wellbore unevenness; (5) When you encounter a blind eye when you drill down, you need to remember the depth of the well, the situation of the eye-catching situation, and the situation in which the subsequent judgment is blocked, and the working time is controlled; (6) When drilling down to a certain distance downhole, it is necessary to turn on the pump running turntable and slowly lower it.
