Description
Technical Field
The utility model relates to a screw rod drilling tool field specifically is a device is prevented clamping by screw rod drilling tool in pit.
Background
The screw drilling tool is a positive displacement downhole power drilling tool which takes drilling fluid as power and converts liquid pressure energy into mechanical energy. When slurry pumped by the slurry pump flows through the bypass valve and enters the motor, a certain pressure difference is formed between the inlet and the outlet of the motor, the rotor is pushed to rotate around the axis of the stator, and the rotating speed and the torque are transmitted to the drill bit through the universal shaft and the transmission shaft, so that the drilling operation is realized. The screw drill which uses mud and clean water as power media and is conveyed to the bottom of a hole through a central hole of a drill rod is an energy conversion device which is used for converting liquid pressure energy into mechanical energy. During drilling, the screw drill directly drives the core tube and the drill bit connected to the transmission shaft at the bottom of the hole to rotate, and the whole drill string is only used as a channel for conveying a high-pressure working medium and a rod piece for supporting the counter torque of the drill bit and does not rotate. Drilling with a screw drill has many advantages over conventional drilling, such as a substantial reduction in drill pipe wear and a high rate of penetration. It is the main instrument for drilling directional hole and has played a role in drilling field.
The existing screw drilling tool is in the drilling process, the drilling tool jamming accident is easy to occur due to complex geology, and when the drilling tool jamming accident occurs, the drilling tool jamming is not movable in a severe soil environment, so that the great economic loss and the time consumed by the maloperation are caused, the well hole scrapping and the field personnel financial damage can be caused due to the untimely treatment, and the great interference is brought to the construction operation.
