AI Technical Summary
Existing ball-dropping devices cannot directly observe the movement and setting process of the temporary plugging ball in the perforation section of a horizontal well, resulting in a lack of intuitiveness and precise control in the ball-dropping process.
A visual observation device for the movement of a temporary plugging ball was designed, including a ball launcher and a perforation section sleeve. The temporary plugging ball is accelerated by an impeller generator and an electromagnetic coil, and is visualized through translucent acrylic glass. The temporary plugging ball is adsorbed at the perforation hole by the impeller generator adsorption device, which improves the accuracy of movement and plugging.
It enables visualization and precise control of the temporary blocking ball delivery process, improves the movement speed and blocking effect, and can simulate the movement and blocking behavior of the temporary blocking ball under different conditions.
