Problems solved by technology
[0003] The existing packer is not equipped with a locking mechanism, which will cause unstable plugging when sealing tubing and oil and gas wells, thus affecting the plugging effect of tubing and oil and gas wells, and tubing and oil and gas wells will be used for a long time In the process, there will be stains on the inner wall, which makes it difficult for the packer to enter the tubing and oil and gas wells. Therefore, in order to correct the above defects, we propose a packer with a locking mechanism and its use method

Description
technical field [0001] The invention relates to the technical field of packers, in particular to a packer provided with a locking mechanism and a use method thereof. Background technique [0002] A packer is a downhole tool that is connected to the downhole tubing string and used to seal off the tubing and the casing of the oil and gas well or the annular space of the open hole wall. [0003] The existing packer is not provided with a locking mechanism. When the oil pipe and the oil and gas well are sealed, the plugging will be unstable, which will affect the sealing effect of the oil pipe and the oil and gas well, and the oil pipe and the oil and gas well will be used for a long time. In order to correct the above defects, we propose a packer with a locking mechanism and its use method. SUMMARY OF THE INVENTION [0004] The technical problem solved by the present invention is to overcome the defects of the prior art, and to provide a packer with a locking mechanism and a...
