    • A downhole tool that is capable of isolating communication pressure from below the set downhole tool, and is capable of being converted to a frac plug is provided. The downhole tool includes a packer with a ball seat defined therein. A plug is disposed at a lower end of the downhole tool to isolate the upper well from the lower well. A sealing ball is carried with the packer into the well by a setting tool. The movement of the sealing ball away from the ball seat is limited by isolation of the sealing ball from the lower well. A rod is disposed through the downhole tool contacting the plug. The rod is partially disposed in the ball seat, preventing the sealing ball from sealing. When the packer is set, flow within the well is isolated, thereby allowing treatment of the well above the packer. With the application of sufficient pressure, the sealing ball applies force to the rod which shears the plug from within the tool. The tool is converted to a standard frac plug.
    • 提供一种井下工具,其能够将通信压力从设置的井下工具下方隔离,并且能够被转换成压裂塞。 井下工具包括限定在其中的球座的封隔器。 一个塞子设置在井下工具的下端以将井与井下隔离开来。 密封球通过固定工具与打包机一起运送到井中。 密封球远离球座的运动受到密封球与下井的隔离的限制。 杆穿过穿过井下工具接触塞子。 杆部分地设置在球座中,防止密封球密封。 当封隔器设置时,井内的流动被隔离,从而允许处理封隔器上方的井。 通过施加足够的压力,密封球对从工具中剪切塞子的杆施加力。 该工具被转换成标准压裂插头。
