Abstract
The utility model provides a ball throwing-type sliding sleeve screen pipe device which comprises a punched screen pipe. An inner sliding sleeve is sleeved in and connected with the punched screen pipe through a destructible locking device; the punched screen pipe is provided with a backstop projection for clamping the top of the inner sliding sleeve; an opening is formed at the bottom end of the inner sliding sleeve; a ball base is arranged at the opening; the inner sliding sleeve is hollow and provided with a ball internally; and the external diameter of the ball is adaptive to the ball base. When in use, the ball throwing-type sliding sleeve screen pipe device is delivered into a completed well, and then the inner sliding sleeve moves downwards under the pressure exerted at the mouth of the well to cut a pin. The downward movement of the inner sliding sleeve can lead the screen pipe to be opened, and the purposes of setting and acid fracturing are achieved.
