Abstract
Handling wellhead assembly be a kind of change for oil field utilize hydraulic power supply to produce in well head process revolving force on shackle load and unload the special tool of well head, which overcome the shortcoming of current technology, it is formed by connecting by oil pipe short circuit, clip, connecting screw, disk, disk top center position welds a clip sheet, oil pipe short circuit is connected with clip sheet by clip, and is fixed by connecting screw; Oil pipe short circuit is 2
7/
8〞 pipe nipple; Disc thickness is 8mm, diameter is 600mm; Disk has KQ65-35 type screw hole and KQ65-21 type screw hole two kinds; And the KQ65-35 type screw hole on disk, KQ65-21 type screw hole and KQ65-35 type, KQ65-21 type well head four-way are corresponding, are fixed by corresponding bolt.
Description
Technical field: the utility model relate to a kind of change for oil field utilize hydraulic power supply to produce in well head process revolving force on shackle handling well head special tool, especially load and unload wellhead assembly.
Background technology: due to the difference of working procedure in our construction, for pressure break, acidifying, squeeze the Large Constructions such as stifled, we often will change well head, manually lift oil pipe shirk for the centering of well head and well head being unloaded all adopt, fill bad just easy tiltedly button, even cause casing coupling to damage, cause overhaul, this just changes well head to us and brings certain difficult problem.
Summary of the invention: it is simple that the purpose of this utility model is to provide a kind of structure, easy to operate handling wellhead assembly, which overcome the shortcoming of current technology, the purpose of this utility model realizes like this, it is formed by connecting by oil pipe short circuit, clip, connecting screw, disk, disk top center position welds a clip sheet, and oil pipe short circuit is connected with clip sheet by clip, and is fixed by connecting screw; Oil pipe short circuit is 2
7/
8〞 pipe nipple; Disc thickness is 8mm, diameter is 600mm; Disk has KQ65-35 type screw hole and KQ65-21 type screw hole two kinds; And the KQ65-35 type screw hole on disk, KQ65-21 type screw hole and KQ65-35 type, KQ65-21 type well head four-way are corresponding, are fixed by corresponding bolt.
Application process of the present utility model: the revolving force utilizing hydraulic power supply to produce drives 2
7/
8〞 pipe nipple, by 2
7/
8〞 pipe nipple drives disk, and disk is also delivered on corresponding well head big four, carries out upper shackle handling well head.
Meaning of the present utility model is: solve a difficult problem of manually lifting tubing handling well head, thus reaches the object of unloading well head.The utility model structure is simple, and easy to operate, operating efficiency is high.
Accompanying drawing illustrates: Fig. 1 is the structural representation of handling wellhead assembly, in figure 1, oil pipe short circuit 2, clip 3, connecting screw 4, disk 5, KQ65-35 type screw attachment holes 6, KQ65-21 type screw attachment holes.
Detailed description of the invention: embodiment 1, the utility model are formed by connecting by oil pipe short circuit 1, clip 2, connecting screw 3, disk 4, disk 4 top center position welds a clip sheet, oil pipe short circuit 1 is connected with clip sheet by clip 2, and is fixed by connecting screw 3.
Embodiment 2, oil pipe short circuit are 2
7/
8〞 pipe nipple.
Embodiment 3, disc thickness are 8mm, diameter is 600mm; Disk has KQ65-35 type screw hole and KQ65-21 type screw hole two kinds; And the KQ65-35 type screw hole on disk, KQ65-21 type screw hole and KQ65-35 type, KQ65-21 type well head four-way are corresponding, are fixed by corresponding bolt.
