Embodiment
This practical particular content is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Multifunction drilling tool release device, including：By main frame and with its phase interworking
The hydraulic system composition of conjunction, the main frame is by frame 1, upper pedestal 2, lower base 3, two elevating rams 4, four side cylinders 5, cunnings
Block 6, flashboard 7 and packing unit 8 are constituted, and two elevating rams 4 are arranged between upper pedestal 2 and lower base 3, two elevating rams
4 lower end is supported on lower base 3, and the piston rod 41 of two elevating rams 4 is connected with upper pedestal 2, on the lower base 2
The flange hole 9 corresponding with wellhead flange is provided with, lower base 2, which is bolted, is fixed on lower base 2 on wellhead flange,
The pedestal inner chamber 10 cooperated with drilling tool tubing string is provided with the upper pedestal 2 and lower base 3, in the upper pedestal 2
Sliding block 6 is respectively arranged with the both sides of pedestal inner chamber 10 of lower base 3, one end of sliding block 6 is connected by bolt 61 with connecting plate 62
Connect, the bolt hole 63 cooperated with bolt 61 is provided with connecting plate 62, connecting plate 62 is fixed on the piston rod of side cylinder 5
On 51, side cylinder 5 is present in intracoelomic cavity 10 with movable slider 6 to be moved left and right, and flashboard 7 is arranged with inside the other end of sliding block 6, in flashboard
If the inner side on 7 is evenly arranged with dry glue core mounting groove 71, packing unit 8 is arranged on the glue core mounting groove 71 cooperated with it
It is interior, the middle part of flashboard 7 is provided with mounting hole 72, the through hole 64 cooperated with mounting hole 72 is provided with the middle part of sliding block 6, Gu
