Description
Technical field
This utility model relates to a kind of oil exploration equipment, a kind of transfers instrument for on-the-spot pipe hanger.
Background technology
Along with the continuous progress and development of science and technology, petroleum drilling technology is also in constantly development.Drilling well region there occurs
Change, gradually excessively arrive desert and ocean away from land, the degree of depth of drilling well the most gradually by shallow to deep the most excessive, the well type of drilling well is also sent out
Give birth to change.But, along with drilling well region, the change of the degree of depth, existing drilling technology can not meet current stone very well
Oil exploitation.
On-the-spot pipe hanger in oil exploration equipment transfers instrument, is currently by the threaded pipe hanger that is in transmission connection.Work as pipe
Hang in decentralization process: if connecting screw thread rotation tension, be then not easy to take out pipe hanger and transfer instrument.If connecting screw thread rotation not
Put in place, then in decentralization process, pipe hanger easily rocks, and is difficult to operation.And, pipe hanger is transferred after putting in place, takes out pipe hanger and transfers instrument
Time, transfer upper tool part due to pipe hanger and also threaded with drilling rod, when causing the rotation pipe hanger instrument of transferring to make it separate pipe hanger
Drilling rod transfer with pipe hanger the screw thread between instrument can follow together with rotate, inconvenient during use.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defect in the presence of above-mentioned prior art, it is provided that a kind of
Maneuverable pipe hanger rotates transfers instrument.
This utility model have employed following technical proposal and solves its technical problem: a kind of pipe hanger rotates transfers instrument, bag
Include the lifting sub that top can be connected with drilling rod, and fix the cylinder being connected with lifting sub, this cylinder inboard wall and pipe hanger
Outer wall is threaded connection, it is characterised in that: it is equipped with between cylinder inboard wall and lifting sub outer wall and can accommodate pipe hanger top
Space, the wall of cylinder is at least equipped with two connecting pins that can move radially, and pipe is hung between cylinder and lifting sub
Top, its outer wall is equipped with the level corresponding with connecting pin to groove, and bottom land one end of this groove is to pipe hanger centre distance and pipe
Hanging outer wall arc radius equal, the other end to pipe hanger centre distance is less than pipe hanger outer wall arc radius.
This utility model is easy to use, processing ease, improves field operation efficiency, reduces Oil Field equipment fault
Rate, decreases the loss in oil field.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of pipe hanger in this utility model.
Fig. 3 be in Fig. 2 A-A to sectional view.
Fig. 4 is this utility model view of connecting pin and pipe hanger upper groove when turning clockwise.
Fig. 5 is this utility model view of connecting pin and pipe hanger upper groove when rotating counterclockwise.
In figure, each sequence number is expressed as:
1 lifting sub；2 cylinders；21 spaces；3 pipe hangers；31 screw threads；32 grooves；321 bottom lands； 4—
Connecting pin；5 hexagon socket cap head screws；6 O-ring seals.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model will be further described.
Seeing figures.1.and.2, this utility model includes the lifting sub 1 that top can be connected with drilling rod, and short with promoting
The fixing cylinder 2 connected of joint 1, this cylinder 2 inwall is connected by screw thread 31 with pipe hanger 3 outer wall.Aforementioned lifting sub 1 and cylinder 2
It is to connect by hexagon socket cap head screw 5 is fixing.
The space 21 that can accommodate pipe hanger 3 top it is equipped with, on the wall of cylinder 2 between cylinder 2 inwall and lifting sub 1 outer wall
At least being equipped with two connecting pins that can move radially 4, in the present embodiment, described cylinder 2 wall is equidistantly equipped with four can
The connecting pin 4 moved radially.
Pipe hanger 3 puts the top between cylinder 2 and lifting sub 1, its outer wall be equipped with the level corresponding with connecting pin 4 to
Groove 32, bottom land 321 one end of this groove 32 is equal with pipe hanger 3 outer wall arc radius to pipe hanger 3 centre distance, and the other end is to pipe
Hang 3 centre distances less than pipe hanger 3 outer wall arc radius.
Lifting sub 1 outer wall bottom is equipped with and can realize circlip groove and the O-ring seals 6 that pipe hanger 2 pressure testing seals.
During use, this utility model first passes through the screw thread 31 that is in transmission connection and connects pipe hanger 3, then by connecting pin 4 through cylinder 2
Wall insert in the groove 32 on pipe hanger 3.When this utility model instrument of transferring turns clockwise and transfers when, connecting pin 4 begins
It is embedded in eventually inside one end of groove, and is stopped by its end face, it is ensured that pipe hanger fetching tool and pipe hanger 3 link together and not
Can loosen.
Now, drilling rod connects transfers instrument and rotates together with pipe hanger 3 and transfer, and makes pipe hanger 3 transfer and sit and is suspended to platform in four-way
On rank, it is ensured that pipe hanger is installed and put in place.
Another mistake hour hands rotate and transfer instrument subsequently, and then connecting pin 4 exits from the other end of pipe hanger 3 upper groove 21, followed by
The continuous screw thread 31 that is rotated up being in transmission connection completes to thread off, and drilling rod extracts the instrument of transferring.
Can effectively improve field operation efficiency by above exploitation design, reduce the fault of the equipment of Oil Field
Rate, reduces the loss in oil field.
