Abstract

The invention provides a drill tool arrangement and placement device. The device is installed on a derrick used for placing drill tools. The device includes a stand column installed on the derrick; the stand column is provided with a centralizer unit used for supporting end portions of the drill tools, and a clamping unit used for fixing the drill tools; the centralizer unit includes a first centralizer unit body and a second centralizer unit body below the first centralizer unit body, and the clamping unit is located between the first centralizer unit body and the second centralizer unit body; the drill tool arrangement and placement device is used for righting and arranging the drill tools through the three operating units, there are several supporting positions, the drill tools are flexible in operation, and processing is easy and efficient. The end portions of the drilling tools are controlled by the centralizer unit, the swing amplitude of each drilling tool can be limited, and the stability and safety of processing is improved.

Description

technical field [0001] The invention belongs to the field of ocean drilling platforms, in particular to a drilling tool discharge device. Background technique [0002] The existing offshore drilling platform drilling tool transfer and discharge device is a split structure driven up and down, and is used to grab and discharge drilling tools, pipe strings and other drilling tools through two grippers respectively arranged on the upper part and the lower part. When the drilling tool is just removed from the beam, or when it is taken out from the well, the drilling tool will have a certain degree of inclination, and it is necessary to move the discharge device for straightening. However, when the length of the drilling tool stand is longer, such as more than 90 feet, it will be difficult for the two grippers to straighten and discharge the drilling tool, and the processing time will be longer, and the drilling tool will easily swing a lot, which has a certain degree of safety. ...
