SQUEEZE CEMENTING TOOL FOR PLACING CEMENT BRIDGING PLUGS

摘要

Usage: for the insulation of productive horizons from each other during testing of exploration and production wells. SUMMARY OF THE INVENTION: In tampo- changes require the projectile is formed with an upper air chamber hollow finger, with the pusher piston, and destructive element, which is disposed above a bailer tampo- changes require the solution and the elastic stopper in a lower part. In the connecting head an axial cylindrical seat in which the destructive element is set as the explosive assembly. -razdelitel below the piston in the initial position holds a bailer additional hole. The lower plunger mounted metal brush, with its expansion into contact with the inner diameter of the casing. When squeezing the elastic tube it is poured plugging solution, the metal brush by moving up the lower Referring pusher clears the inner surface of the column, which improves the quality of bonding grouting material Ko pubic and improves the quality Fitting bridges. 1 ZP f ly-3-yl. ate with
