1. The single-point inclination measurement must be carried out after the kelly is drilled and before a single one is connected. The inclinometer is in the process of tripping and drilling, and the drilling tool is moved once every 1-2 minutes, and the distance is not less than 2 meters.
2. During drilling, always observe the value of the weight gauge and the pump pressure gauge. If the overhang is reduced and the pump pressure drops, immediately find the cause, first find the ground cause, if the ground cause is eliminated and it still does not return to normal, immediately trip out and check.

3. During drilling, you should pay attention to the amount of sand in the vibrating screen. If the sand is found to increase, you should observe whether the sand sample is collapsed. If the reduction of sand is found to be a change in the performance of the drilling fluid and the poor rock-carrying ability, measures should be taken in time to deal with it.
4. After drilling, the drill bit is more than 2-3 meters away from the bottom of the well (usually a single root is lifted) and the pump is turned on. When the pump is turned on, the speed of the diesel engine is 800-900 rpm.
5. Sending drills: The spirit must be concentrated, and it can be sent by point or by slip. It is required to send the drill evenly, watch the finger weight table, and observe the lowering speed of the roller or the rope at the same time, so as to keep up with the drilling pressure without slipping the drill. It is strictly forbidden to pressurize the drill bit to start the drill disc.
