Abstract

The invention discloses an automatic derrick device suitable for double-wellhead pipe arrangement operation. The automatic derrick device comprises a pair of longitudinal rails. The longitudinal rails are each provided with a longitudinal moving pulley. A transverse rail is fixedly connected to the upper portions of the two longitudinal moving pulleys. The middle of the transverse rail is connected with a derrick of a drilling machine through a longitudinal driving hydraulic cylinder. A transverse moving pulley is mounted in the transverse rail. A slewing mechanism is mounted on the transverse moving pulley and is in transmission connection with a transverse driving motor. The lower end of the slewing mechanism is fixedly connected with the upper portion of an inclined arm. The lower portion of the inclined arm is hinged to an outer cylinder of a telescopic arm. A pair of gripping pliers is mounted at the lower end of an inner cylinder of the telescopic arm. The invention further discloses a method for stand arrangement through the automatic derrick device. The device and method meet the requirement of the double-wellhead drilling machine for simultaneously conducting stand establishing, tripping, casing running and other operation.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, and relates to an automatic derrick operator suitable for double wellhead pipe arrangement operations, and also relates to a method for using the automatic derrick operator to perform stand discharge. Background technique [0002] The automatic derrick is a device used for the discharge operation of the second-floor platform of the oil drilling rig. The current automatic derrick is only suitable for single wellhead piping operations. It can only stand the drill pipe or drill collar in a single wellhead and stand area. Delivered back and forth. An automatic derrick has been invented, which can be applied to double wellhead piping operations. It can discharge the drill pipe stand or drill collar stand from any wellhead to any position in the stand area, and can also discharge the drill pipe stand or drill collar stand Delivered from any position in the stand area to any wellhe...
