Power catwalk machine capable of feeding and throwing three drilling and exploitation tubular columns

Abstract

The invention relates to a power catwalk machine capable of feeding and throwing three drilling and exploitation tubular columns, and belongs to the field of petroleum drilling and exploitation equipment. The power catwalk machine comprises a base rack, a supporting arm, a ramp, a sliding arm and a tackle assembly. A containing groove is formed in the base rack, and a supporting arm sliding rail is arranged in the containing groove. One end of the supporting arm is in sliding connection to the supporting arm sliding rail. One end of the ramp is in pin connection with one end of the base rack,and a sliding arm sliding rail is arranged on the ramp. The other end of the supporting arm and the bottom of one end of the sliding arm are hinged, the other end of the sliding arm is arranged on thesliding arm sliding rail in a sliding manner, three V-shaped sliding grooves are formed in the sliding arm, communicating turnover openings are formed in the three V-shaped sliding grooves, and pipeturnover devices used for turning over the tubular columns placed in the three V-shaped sliding grooves out of the sliding arm are arranged in the turnover openings. The tackle assembly is in slidingconnection to the three V-shaped sliding grooves in a sliding manner. Through the power catwalk machine, three drilling and exploitation tubular columns can be fed and thrown at a time, the manner offeeding and throwing only one drilling and exploitation tubular column at a time in tradition is changed, and work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of oil drilling and production equipment, in particular to a power catwalk machine for sending and throwing three drilling and production strings. Background technique [0002] At present, domestic oil drilling and production automation equipment is gradually paying attention, especially the power catwalk machine, which is gradually popularized and used in China. The power catwalk machine is mainly used for drilling and production placed on the pipe rack. The pipe string is transported to the drilling floor, and the drilling and production pipe string is transported from the drilling floor to the pipe rack. [0003] However, at present, the domestic power catwalk machine still adopts the method of sending and throwing a single root, and the method of sending a single root can basically meet the normal requirements of oil drilling and production in terms of efficiency. However, when the drilling and production string ...

Problems solved by technology

[0003] However, at present, the domestic power catwalk machine still adopts the method of sending and throwing a single root, and the method of sending a single root can basically meet the normal requirements of oil drilling and production in terms of efficiency.

However, when the drilling and production string needs to be transported from the drill floor to the pipe rack, the method of throwing a single string will take a long time to throw the string, and the delivery efficiency is too low, which cannot meet the requirements of the drill throwing after the completion work, resulting in the completion of the well. The follow-up work time is too long, affecting the new drilling progress

Therefore, the current power catwalk machine cannot meet the requirements of on-site use very well.
