Abstract
The utility model discloses a tail pipe is hung and is sent into instrument chuck, including chuck body, extend on the chuck body both sides has the support arm, be the clamp between two support arms, is equipped with protection baffle plate on chuck body upper portion, and protection baffle plate one end hinges with one of them support arm, and the other end is equipped with the pinhole, also is equipped with the pinhole on another support arm, and protection baffle plate passes through the foxtail, the pinhole is fixed on another support arm, distance between two support arms is less than ball seat recess external diameter. The utility model discloses a chuck can have quick, convenient characteristics at adapter sleeve plug assembly and liner hanger under the condition that does not occupy the well head, can effectively improve the operating efficiency.
Description
Technical field
The utility model belongs to the technical field of marine oil gas field drilling well, specifically refers to that running tool chuck hung by a kind of tail pipe.
Background technology
THE WESTERN SOUTH CHINA SEA area HTHP gas field development well type is directional well, compare with straight well, inclined shaft tail pipe is not in place under existing, concentration degree is more difficult to control, wall cake removes a more difficult difficult problem, adopt conventional cementing technology will be difficult to ensure tailpipe section cementing quality, and the frictional resistance that rotary tail cementing technology enters under can reducing tubing string, risk not in place under reducing tail pipe.For ensure tail pipe smooth under enter and the cementing quality of development well tailpipe section, HTHP gas field development application rotary tail extension instrument.Before entering well, ball seat part (plug assembly) is what to be separated with extension hanger part, these two parts are connected at rig floor with regard to needs during lower tail pipe, tail pipe is produced owing to entering down 177.8mm in now pit shaft, need throwing pipe basis ball seat part/sleeve pipe plug assembly being connected to extension hanger bottom in rat hole, hanger bottom fitting can be connected on last root sleeve pipe after connecting.
Utility model content
The purpose of this utility model is to provide a kind of ball seat part can connection with the polishing pipe of extension hanger bottom quickly and safely at rat hole place, avoids taking well head, rapid and convenient, and running tool chuck hung by the tail pipe effectively improving operating efficiency.
For realizing above-mentioned object, the technical solution of the utility model is: running tool chuck hung by a kind of tail pipe, comprise chuck body, chuck body both sides are extended with support arm, be clip, be provided with protection baffle plate on chuck body top between two support arms, protection baffle plate one end is with wherein a support arm is hinged, the other end is provided with pin-and-hole, and another support arm is also provided with pin-and-hole, and protection baffle plate is fixed on another support arm by pin, pin-and-hole; Distance between two support arms is less than ball seating grooves external diameter.
Preferably, the shape of described clip is semicircle, and semicircular structure can better contact by tubing string circular with ball seat, increases stability.
Adopt chuck of the present utility model can block the neck place of ball seat/sleeve pipe plug, the ball seat (splicing sleeve plug assembly) below neck is allowed to put into rat hole, realize connecting polishing pipe at rat hole place, do not taking situation lower joint sleeve pipe plug assembly and the extension hanger of well head, have fast, feature easily, effectively can improve operating efficiency.The utility model also has the feature that structure is simple, cost is low, easy to operate, can extensive use in oilfield drilling operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model pin structural representation;
Fig. 3 is the utility model ball socket structure schematic diagram.
In figure: 1 chuck body, 2 support arms, 3 clips, 4 pin-and-holes, 5 protection baffle plates, 6 pins, 7 ball seats, 71 necks, 72 plugs.
Detailed description of the invention
As shown in Figure 1,2 and 3, running tool chuck hung by tail pipe of the present utility model, comprise chuck body 1, chuck body 1 both sides are extended with support arm 2, are clip 3 between two support arms 2, are provided with protection baffle plate 5 on chuck body 1 top, protection baffle plate 5 one end is with wherein a support arm is hinged, the other end is provided with pin-and-hole 4, and another support arm is also provided with pin-and-hole 4, and protection baffle plate 5 is fixed on another support arm by pin 6, pin-and-hole 4; Distance between two support arms 2 is less than ball seat 7 groove (i.e. neck 71) external diameter.The shape of above-mentioned clip 3 is semicircle, and semicircular structure can better and circular tubing string contact, increase stability.Chuck body 1 is similar to rectangle structure, rectangle structure, the steel material that body material selection is general, and length and width are thick is respectively 40cm × 30cm × 1.5cm.Strengthen the firm effect to running tool by protection baffle plate 5, avoid tubing string transverse movement slippage.Pin inserts pin-and-hole, and pin size and pin-and-hole size should be mated, and pin body diameter is 1.8cm, pin body is long is 10cm, pin-and-hole opening diameter 2cm, and pin 6 should with pin cap, pin cap is cylindricity structure, and diameter slightly larger than pin body, should cut across pin-and-hole with stop bolt pin.Steel material all should be selected to process, to avoid corrosion-deformation with the material of upper-part.
Tail pipe of the present utility model is hung running tool and to be met an urgent need chuck, and concrete operations are as follows:
1. use rig floor crane that extension hanger is winched to rig floor, coordinated by winch, top is driven and scoops out extension hanger, keep vacant state;
2. rig floor winch is used to winch to rig floor from rig floor upper deck by the ball seat being connected with sleeve pipe plug assembly;
3. emergent chuck is stuck in the groove of ball seat, and fixes;
4. enter under the ball seat being connected with emergent chuck to rat hole, and make ball seat neck place be stuck on chuck;
5. by using top to drive, extension hanger is made to move to above ball seat, both connections;
The ball seat connected and extension hanger are inserted tail pipe string, and union tail is hung and tail pipe, the operation of lower production tail pipe.
Generally speaking, chuck of the present utility model contributes to connecting ball seat part (sleeve pipe plug assembly) and extension hanger when not taking well head, has feature quickly and easily, effectively can improve operating efficiency.
The above is preferred embodiment of the present utility model; certainly the interest field of the utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection domain of technical solutions of the utility model.
