Abstract
The utility model relates to the technical field of coiled tubing well drilling and repair, in particular to a wellhead hanging device for a downhole coiled tubing tool string. According to the wellhead hanging device, rectangular grooves are formed in a double-lug half tray and a single-lug half tray respectively, one end of the double-lug half tray and one end of the single-lug half tray are connected through a lug plate pin, the other end of the double-lug half tray and the other end of the single-lug half tray are connected through a baffle, the baffle is connected to connecting holes of the rectangular grooves through bolts and nuts, semicircular through holes are formed in the double-lug half tray and the single-lug half tray respectively, the two semicircular through holes are combined into a circular through hole when the double-lug half tray and the single-lug half tray are combined together in a buckling mode, and handles are welded to the double-lug half tray and the single-lug half tray respectively. According to the wellhead hanging device for the downhole coiled tubing tool string, the purpose that when connection or disassembly is carried out on tools, the downhole coiled tubing well repair or drilling tools can be clamped and hung through the wellhead hanging device is achieved, and the defect that in the prior art, no devices are used for clamping and hanging the downhole coiled tubing well repair or drilling tools when the tools are connected or disassembled is overcome.
Description
Technical field:
The utility model relates to a kind of continuous-tube drilling and repairing well technical field, particularly a kind of continuous-tube underground tool string wellhead hookup.
Background technology:
Continuous-tube operation technique has obtained application to a certain degree in each oil field at home at present, and continuous-tube drilling technology is still in the starting stage.At the well head of wanting to carry out continuous-tube construction, be not also used for blocking and hang the continuous-tube well workover of going into the well or the device of drilling tool when carrying out the connection of instrument or when dismounting.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of continuous-tube underground tool string wellhead hookup, and this device has been realized and in the time carrying out the connection of instrument or dismantle, can be used for blocking and hanging continuous-tube well workover or the drilling tool of going into the well.Overcome that existing instrument connects or be not also used for blocking and hang the continuous-tube well workover of going into the well when dismounting or the deficiency of the device of drilling tool.
Technical solution adopted in the utility model is: a kind of continuous-tube underground tool string wellhead hookup, comprises ears half pallet and monaural half pallet; On ears half pallet and monaural half pallet, be all processed with rectangular channel, ears half pallet is connected by otic placode pin with monaural half pallet one end, ears half pallet is connected by baffle plate with the monaural half pallet other end, baffle plate is connected to by bolt and nut on the connecting hole of rectangular channel, on ears half pallet and monaural half pallet, be all designed with half-round cross hole, when ears half pallet and monaural half pallet snap together, two half-round cross holes are combined as a full circle through hole, on ears half pallet and monaural half pallet, are all welded with handle.
End face and the bottom surface of the half-round cross hole on ears half pallet and monaural half pallet are all processed with interior chamfering.
The beneficial effects of the utility model are: the utility model is due to the mode that has adopted ears half pallet and monaural half pallet to match, thereby have and in the time carrying out the connection of instrument or dismounting, can block and hang the continuous-tube well workover of going into the well or the function of drilling tool.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of continuous-tube underground tool string wellhead hookup, comprises ears half pallet 1 and monaural half pallet 2; On ears half pallet 1 and monaural half pallet 2, be all processed with rectangular channel, ears half pallet 1 is connected by otic placode pin with monaural half pallet 2 one end, ears half pallet 1 is connected by baffle plate 3 with monaural half pallet 2 other ends, baffle plate 3 is connected to by bolt and nut 4 on the connecting hole of rectangular channel, on ears half pallet 1 and monaural half pallet 2, be all designed with half-round cross hole, when ears half pallet 1 and monaural half pallet 2 snap together, two half-round cross holes are combined as a full circle through hole, on ears half pallet 1 and monaural half pallet 2, are all welded with handle.End face and the bottom surface of the half-round cross hole on ears half pallet 1 and monaural half pallet 2 are all processed with interior chamfering.
