The coiled tubing hydraulic activation lead impression is mainly used in the workover operations of highly deviated wells and horizontal wells. It is used to solve the problem of lead mold accuracy caused by premature damage to the lead mold in the workover operations in complex wellbores.
After the lead impression run into the well, the conventional coiled tubing tool has been running close to the bottom, which is easy to cause the wear of the lead impression. The new coiled tubing tool-hydraulic activation lead impression allows the tool string to establish fluid circulation. When the lead impression operation is required, the ball is dropped from the wellhead, and the lead impression can be started by pressure, and it is automatically locked after starting.
The operation of this tool can achieve accurate measurement and avoid damage to the lead impression during the well, which can effectively improve the operation efficiency.
