The invention discloses an automatic processing method for pipe strings of a 2-single-piece 1-column drilling rig, in which a power drill pipe box and a power catwalk are arranged side by side on the ground in front of the drilling rig, and a buffer manipulator is installed on the drilling rig deck, and the drilling rig deck is also installed There are iron drillers, mud blowout prevention boxes, and power elevators. The iron drillers are installed in the area between the mouse hole and the wellhead. The power slips are installed in the turntable of the drilling rig, and the power elevators are suspended on the rings of the drilling rig's traveling suspension system. Above, the built-up 2 single 1 column is stored in the power drill pipe box, and the power catwalk is used to transport 2 single 1 column. The present invention is an automatic processing method for 2-single-1-column drilling rig strings, which solves the time-consuming problems in the prior art in the establishment of columns and single-column removal.
Description
technical field [0001] The invention belongs to the technical field of oil and gas drilling and production equipment, and relates to an automatic processing method for 2-single-1-column drilling machine strings. Background technique [0002] Conventional drilling rigs use 3 singles and 1 column for drilling operations, and the automatic processing system of pipe strings needs to build up the individual columns one by one in advance or during the drilling waiting period, and discharge the columns in the second-floor platform finger beam for use. When drilling with the column connected, the manipulator or worker of the second-story platform will take the column out of the finger beam of the second-story platform and hand it over to the top drive to continue drilling. After the drilling is completed, the columns are first stored in the finger beam of the second-floor platform. After the well logging meets the requirements, the columns are taken out from the finger beam of the s...
