Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] As shown in Fig. 1, the present invention comprises multi-station rat hole 1, derrick 4, pipe gripping manipulator 2 and iron driller 3, and described multi-station rat hole 1 is fixed below drilling platform 5, and provides at least two Drill pipe insertion station; the derrick 4 is fixed on the drilling platform 5; the pipe grabbing manipulator 2 is fixed on the derrick 4, and is used to pick up the drill pipe 40 conveyed by the catwalk machine 30 and put it into the mouse hole body and from Drill pipes are raised from the mouse hole body; the iron driller 3 is arranged on the drilling platform and is used for docking two drill pipes.

[0024] As shown in Figure 2, the multi-station rathole includes a top support frame 11, two rathole bodies 14, 15 and a drill pipe centering device 12, a lifting hydraulic pressure Cylinder 16, drill pipe buffer device 17 an...

Abstract

The method disclose a drilling platform pipe racking system, which comprises a multi-station mouse hole, a derrick, a pipe grabbing mechanical hand and an iron roughneck, wherein the multi-station mouse hole at least provides two mouse hole-body drill stem insertion stations; a drill stem aligning device, a lifting cylinder, a drill steam buffer and a lifting pulley block are correspondingly arranged in the mouse hole body one to one; the pipe grabbing mechanical hand grabs drill stems in turn, puts the drill stems into the mouse hole body and joints the stems after the drill stems are pulled outside the mouse holes. The invention also discloses a method for racking pipes by the system. In the invention, a multi-station mouse hole structure providing at least two pipe racking stations is adopted, so two single pipes can be arranged in the mouse holes simultaneously; when the third single pipe is jointed, the third pipe can be directly connected with the rest single pipes; and thus, the production efficiency is greatly improved. Besides, the drill stem can be changed from a horizontal state into a vertical state by only one piece of equipment, namely the pipe holding mechanical hand, so the equipment use ratio is greatly improved, the space is saved and the equipment operation is simplified.

Description

technical field [0001] The invention relates to a drilling construction equipment and method, in particular to a drilling platform pipe arrangement system and a pipe arrangement method. Background technique [0002] In the process of drilling construction, drill pipe butt jointing is one of the important pipe arrangement procedures. The number of each pipe arrangement is three, and it needs to be butt jointed twice. The current drilling platform piping system generally uses a single-station mouse hole to complete the docking of the drill pipes. After the first docking, the drill pipes that have been docked need to be taken out and temporarily placed on other equipment, and then to the single station. Put the third drill pipe into the hydraulic mouse hole of the station, retrieve the connected drill pipe, and complete the docking. The above-mentioned system only provides one pipe arrangement station, so the drill pipe must be taken out after the first butt joint, and the wor...
