    • Apparatus and methods for performing downhole operations. The apparatus can include a sealing mechanism having an inner bore formed therethrough; a check valve adjacent the sealing mechanism; a circulation device adjacent the check valve; and a rotatable nozzle adjacent the circulation device. The circulation device can include a first tubular member having a radial hole formed therethrough, and a second tubular member disposed about at least a portion of the first tubular member. The second tubular member can also have a radial hole formed therethrough, and the second tubular member can be adapted to longitudinally move about the first tubular member from a first position to a second position.
    • 用于进行井下作业的装置和方法。 该装置可以包括具有穿过其形成的内孔的密封机构; 与密封机构相邻的止回阀; 与止回阀相邻的循环装置; 以及邻近循环装置的可旋转喷嘴。 循环装置可以包括具有穿过其形成的径向孔的第一管状构件和围绕第一管状构件的至少一部分设置的第二管状构件。 第二管状构件还可以具有穿过其形成的径向孔,并且第二管状构件可以适于围绕第一管状构件从第一位置纵向移动到第二位置。
