API inner Oil well cementing Oilfield Internal Cutter hydraulic casing cutter
At present, the conventional treatment for casing corrosion caused by oil well production in the later stage is to replace the corroded casing. After the original corroded or perforated casing is cut and recycled, a new casing connector is inserted and reconnected to the old casing. To ensure the cutting effect when cutting corroded casing, it is generally necessary to continue cutting for a period of time after the pump pressure drops significantly and it is judged that the casing has been cut to ensure the cutting effect. However, due to the fact that conventional hydraulic internal cutters can cut through corroded casing, if cutting continues, they can cut through double or even multiple layers of casing, thereby damaging the outer casing. To prevent the outer casing from being cut during the cutting process, a single-layer casing single pipe hydraulic cutter is generally used for cutting.
Summary:
(1) The single pipe hydraulic cutter can effectively ensure that the inner casing is not cut to the outer casing during the cutting process, effectively ensuring the safety of the outer casing during the operation.
(2) During the cutting process of a single-layer hydraulic cutter, before confirming that the casing has been cut open, ensure the rotation status of the turntable to prevent changes in the cutting position caused by stopping the turntable.
(3) In the initial stage of ssingle pipe hydraulic cutter, maintain a low displacement and low pump pressure for cutting, gradually increase the displacement and pump pressure to improve cutting efficiency and ensure the final cutting effect.
