[0020] like Figure 1-6 As shown, a transfer device for a coiled tubing blowout preventer comprises a base frame 1, a blowout preventer fixing assembly is connected to the top surface of one end of the base frame 1, a conversion joint positioning seat 2 is provided on one side of the blowout preventer fixing assembly, the conversion joint positioning seat 2 is welded to the base frame 1, a support frame 3 is connected to the center position of the top surface of the base frame 1, a support plate 4 is connected to the top of the support frame 3, and the center of gravity of the equipment is supported by the support plate 4.

[0021] Two symmetrically arranged outer sleeves 5 are connected to the top surface of the base frame 1 away from one end of the lubricator fixing assembly. The outer sleeves 5 are welded to the base frame 1 through a mounting frame 12. The bottom of the mounting frame 12 is welded to the base frame 1, and the outer sleeves 5 are connected to the top of the mounting frame 12.

[0022] A transport skid inner tube 6 is inserted into the two outer sleeves 5. Fixing holes 7 are provided on the outer sleeve 5 and the transport skid inner tube 6. The transport skid inner tube 6 is fixed in the outer sleeve 5 by inserting a fixing pin 8 into the fixing hole 7. A rotating flange fixing tube 9 is connected to the outer wall of the transport skid inner tube 6. A rotating flange 10 is sleeved on the rotating flange fixing tube 9, and the rotating flange 10 is clamped on the rotating flange fixing tube 9 through a baffle 11 connected to the outer wall of the rotating flange fixing tube 9.

[0023] The lubricator fixing assembly includes a lubricator lower straightening tube 13 connected to the base frame 1, a lubricator protection frame 14 is provided on the outer side of the lubricator lower straightening tube 13, the bottom of the lubricator protection frame 14 is fixed on the base frame 1, and a buffer rubber pad is provided on the inner wall of the lubricator protection frame 14.

[0024] Four lifting ears 15 are connected to the top surface of the base frame 1 .

[0025] The coiled tubing operation device includes: a liquid discharge four-way, a coiled tubing four-gate blowout preventer, a large-diameter suspension device, a pressure relief tee, an operating platform, a blowout preventer, a reducer, etc. When in use, the liquid discharge four-way, the four-gate blowout preventer, the large-diameter suspension device, and the pressure relief tee are connected together with bolt steel rings, and the operating platform is connected to the pressure relief tee by hexagon socket screws, so that these devices form a main machine string. During transportation, the liquid discharge four-way is bolted to the rotating flange 10. Since the inner tube 6 of the transport skid can be rotated, the whole machine string can be laid down for transportation. During operation, the whole machine string is erected and the connecting bolts at the rotating flange 10 are removed, and the whole machine string is directly hoisted and connected to the wellhead.
