3.Packer Underground inverse -clamp off device
To improve the speed and effects of clamping off, especially to solve the clamping off problem on account of well leakage, the company has designed the underground inverse -clamp off changeover device. The water enters the device from oil jacket annular in the process of clamping off, and water changes the direction enter the casing going on the sand surface, then lifted the sand of casing. The sand-laden fluid drew inpours from the casing to tubing, and then the sand-laden fluid can be taken to the ground smoothly.
