Description
Technical field
The invention belongs to petroleum drilling technology fields, especially provide a kind of derrick base Intelligent Installation mobile device.
Background technique
It during drilling well or well workover, needs preventer or blowout preventer being installed to well head, to prevent gas blowout accident
Occur, first have to transfer it during installation, earliest using the mode drawn, but such mode is manually lifted, takes
When it is laborious.It was hung later using hook master, the mechanization mounting means of small hook cooperation in this way, although efficiency has significantly
It improves, but on the one hand, working efficiency is still low, and security risk is more, on the other hand, since well head has various supporting supports, shut-in well
Device is not easy directly to be lifted into well head.In China's reality later, that notification number CN202706965U, the day for announcing are 2013.01.30
The oil drilling blowout preventer transfer device disclosed in new patent transfers envelope by the way of moving trolley in orbit
Well device, it greatly improves the efficiency of installation and safeties, but firstly, its trolley can only one-dimensional movement in orbit, that is, hang
After playing blowout preventer, blowout preventer can only be moved left and right or is moved forward and backward, and then do lifting motion again, and not can guarantee all around
Two-dimensional movement, also need manually to go push-and-pull to be installed after blowout preventer moves to a position to suitable position in this way, this
Sample working efficiency and precision still do not reach requirement, and more people is needed to go to operate；Secondly, after when shut-in well, it reaches suitable position, by
In being in soft suspension status, blowout preventer is unstable, can especially put in the state of having wind in swing state slightly
It is dynamic bigger, it is time-consuming even if being also required to wait blowout preventer steady for a long time in calm state, and also installation accuracy is not
It is high；In addition, the pipeline due to well head will be matched with the pipeline of shut-in well below, the transmitting place precision of blowout preventer it requires
It is required that it is high, but above-mentioned apparatus is unable to reach required precision, needs repeatedly to try just find the position really assembled, cause
Its installation effectiveness further declines.
