Abstract

The invention discloses an automatic treatment method for a two-single-oil-pipe one-upright pillar drilling rig string. A power drill pipe box and a power catwalk are arranged on the ground in front of a drilling rig side by side; a buffering manipulator is installed on a table top of the drilling rig; an iron roughneck, a mud blowout preventing box and a power lifting sub are also installed on the table top of the drilling rig; the iron roughneck is installed in an area between a mouse hole and a well mouth; a power slip is installed in a turntable of the drilling rig; the power lifting sub is suspended on a lifting ring of a travelling and lifting system of the drilling rig; a two-single-oil-pipe one-upright pillar which has been constructed is stored in the power drill pipe box; and thecatwalk is used for conveying the two-single-oil-pipe one-upright pillar. According to the automatic treatment method for the two-single-oil-pipe one-upright pillar drilling rig string disclosed by the invention, the problems of time consumption in the processes of constructing the upright pillar and detaching the upright pillar into single oil pipes in the prior art are solved.

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...
