It was found that and the protection advantages such as reservoir.In recent years, each oil gas field is widely applied at home, and obtains applications well effect.
According to " air drilling specification first part: air drilling, nitrogen injection drilling, Air Mist Drilling, nitrogen mist
Change drilling well, air foam well-drilling " regulation: sediment outflow pipeline uses flanged joint in well site, preferably straight to connect out outside well site.But
Often because field condition limits (including rig substructure structure and ground installation are put), it is necessary to adjust drain pipe using bend pipe
Line trend, only in this way can just pick out outside well site.Since the bending angle of existing bend pipe is fixed and invariable, however it is big absolutely
Most of the time, the installation of live sediment outflow pipeline all have no idea it is stringent, accurately according to fixed angle bend pipe direction arrange.Gu
The bend pipe for determining angle can not arbitrarily adjust the angle of itself according to on-site actual situations.Therefore, during the installation of sediment outflow pipeline,
Through often mounting and dismounting repeatedly frequently with tentative connection method, until adjusting until trend of sediment outflow pipeline.In addition
Sediment outflow pipeline weight is very big, causes pipeline to install inconvenient.This not only considerably increases the installation exercise time, increases
The workload and working strength of staff, also improves operating personnel's cost and crane cost of use, or even will cause brill
Machine etc. stops, and extends the serious consequence of drilling period.
In the prior art, suitable for the sediment outflow pipeline of gas drilling, publication number 201412067, publication date 2 months 2010 24
Day, a kind of clamping hoop type sediment outflow pipeline connection type is described, this is also that current gas drilling field sediment outflow pipeline uniquely connects
Mode.The invention is a kind of connection type, can not arbitrarily adjust pipe string angle and trend during the installation process, be still and adopt
It with tentative connection method, often mounts and dismounts repeatedly, working strength and activity duration are all very high.
In addition, gas drilling is in safe sediment outflow manifold, publication number 203188949, publication date 2013.09.11 is described
A kind of device (rupture disk) of sediment outflow pipeline pressure release, suppresses when pipeline internal pressure and is raised to certain value, and rupture disk opens pressure release to reach
To the purpose for ensureing pipeline safety.But pipeline described in the invention is still conventional line, can not during the installation process with
Meaning adjustment pipe string angle and trend, is still using tentative connection method, often mounts and dismounts repeatedly, working strength and
Activity duration is all very high.
Summary of the invention
It is an object of the invention to overcome the above problem of the existing technology, a kind of achievable angle universal adjustment is provided
Gas drilling manifold system.The present invention can light, convenient, optionally adjust sediment outflow pipeline trend, quickly by sediment outflow pipeline
It connects out outside well site, avoids mounting and dismounting repeatedly, the workload and working strength of staff is greatly lowered, shorten installation

When occurring impurity (landwaste, sand etc.) blocking between 10 spherical surface of bulb pipe nipple, which can be by rotating Universal rotary
The mode for turning pipe nipple 13 strikes off impurity.Respectively there is a road sealing groove for pacifying inside Universal rotary pipe nipple 13 and flexural pivot flange 11
Put " O " type sealing ring 2, when installation needs coating butter herein.
Hard tube spool body C is that existing matured product may be selected, and meets API relevant criterion.
The present invention first mentions radial 360 ° of stepless angle shift mechanism A and universal angle micro-adjusting mechanism B before installation and arrangement
Before assemble, then directly as needed will radial 360 ° of stepless angle shift mechanism A, universal angle micro-adjusting mechanism B and hard tube spool C
Body carries out flexible combination can (Fig. 1 show one of manifold system arrangement).Assembly first can assemble diameter in two steps
To 360 ° of stepless angle shift mechanism A, universal angle micro-adjusting mechanism B is reassembled, it then will radial 360 ° of stepless angle shift mechanism A and universal
Angle fine-adjustment mechanism B is connected by way of flange or clip.It, should when assembling radial 360 ° of stepless angle shift mechanism A
Flange 5, self-aligning thrust roller bearing 15, dust-proof nylon circle a16, semicircle card 3,18 and of cylindrical roller thrust bearing will successively be hung
In dust-proof nylon circle b17 injection rotating short-knot 6, pipe nipple 1 then is fixed in pressure, long bolt external member 4 is finally penetrated and tenses.Herein
In the process, it needs to apply to place at self-aligning thrust roller bearing 15, cylindrical roller thrust bearing 18 and " O " type sealing ring 2 three
Smear enough butter.When assembling universal angle micro-adjusting mechanism B, flexural pivot flange 11 and Universal rotary pipe nipple 13 are directly passed through into long spiral shell
Bolt external member 12 tenses, and pays attention to smearing enough butter to " O " type sealing ring 2.
If the present invention is used in sediment outflow pipeline, arrival end and outlet end can be flanged joint, be also possible to clip company
It connects, specific connection type is determined by adjacent lines connection type.Meanwhile fixed pipe nipple 1, semicircle card 3, suspension flange 5, rotation are short
Section 6, blind plate 8, fixed bulb pipe nipple 10, flexural pivot flange 11 and Universal rotary pipe nipple 13 are all made of the casing that grade of steel is J55 and N80
Material is made and (meets API standard).
Rotating short-knot 6 can make 360 ° of rotations around the axis of fixed pipe nipple 1, realize azimuthal stepless transformation.Universal rotary
Universal rotational can be made around the spherical surface of fixed bulb pipe nipple 10 by turning pipe nipple 13.After the azimuth of rotating short-knot 6 is adjusted in place,
It can be finely adjusted by azimuth, inclination angle of the Universal rotary pipe nipple 13 to downstream line.Universal rotary pipe nipple 13 can be around fixation
The spherical rotary of bulb pipe nipple 10, rotation angle can be from -10 ° to 10 °, can also be from -35 ° to 35 °.Rotation angle range can
To be designed for different situations to meet the needs of practical application.Radial 360 ° of stepless angle shift mechanism A and universal angle
Micro-adjusting mechanism B collective effect realizes the step-less adjustment of pipeline trend (azimuth, inclination angle).
