Screw drilling tools are widely used in the oil industry, and what are the matters needing attention in the process of drilling? The following is for you to introduce the specific matters needing attention when using:

1. When 1 ~ 2m from the bottom of the well, start the pump and start the screw drilling tool. When the flow rate reaches normal, record the riser pump pressure. 2. Slowly pressurized drilling, the riser pressure continues to rise, the riser pressure rise value should not be greater than the recommended large pressure difference of the screw drilling tool. If the pressure rise is too large, the drilling tool should be lifted, and then slowly pressurized drilling after the pressure is restored. In the process of drilling, pay attention to the selection of faster footage on bit weight. 3. Correctly record the service time to prevent the service life of the screw drilling tool from being exceeded.
