The invention discloses a
drill string arranging method for push-supporting-type
pipe string treatment equipment under the top-drive-free working condition. The
drill string arranging method mainly comprises the technological processes that step 1, a large hook is connected to the lower part of a
traveling block of a push-supporting-type
pipe string
treatment system; step 2, a
drill string is lifted away from the
drill floor surface by using a
winch through the hook, a
drill floor push-supporting arm is placed at the lower end of the
drill string, and
drill string arranging work is prepared; 3, the lower end of the
drill string is pushed and supported to the drill string arranging position through the
drill floor push-supporting arm; 4, the large hook falls through the
traveling block, andthe lower end of the drill string falls to the position near the designated position; step 5, a tackle
assembly of a
manipulator is moved to the inner side of a track, a mechanical arm
assembly extends out, and the upper end of the drill string is supported through a tong head; and step 6, the large hook falls again, the lower end of the drill string is placed in place, and meanwhile the
manipulator is operated to place the upper end of the drill string to the drill string arranging position specified on a
racking platform. Through two times of falling of the large hook, the offset of the upper end of the drill string in the drill string arranging process is effectively controlled, and the reliability of the drill string arranging process is improved.
