Technical field
The present invention relates to fine controlled pressure drilling equipment technical fields, more particularly to a kind of to bore for fine pressure control
Well is switched fast part flow arrangement.
Background technique
Each elephant is widely applied fine controlled pressure drilling technology at home at present, control pressure line during fine controlled pressure drilling
It is connected to well head, i.e. liquid-operated flat valve exports, and will occupy drilling crew after fine control pressure line connection and pressure testing qualification and often uses drilling well
Liquid circulation canal, common drilling fluid circulation canal are as follows: annular space → rotating blowout preventer → liquid-operated flat valve → fine control pressure line →
Fine pressure control throttling control sled → slurry tank.
During fine controlled pressure drilling because when situ of drilling well actual condition reason stops fine controlled pressure drilling drilling fluid have with
Lower two kinds of endless form:
Circulation of drilling fluid mode one: annular space → rotating blowout preventer → liquid-operated flat valve → fine pressure control process → slurry tank；
Circulation of drilling fluid mode two: annular space → drilling spool → choke manifold group → liquid-gas separator → slurry tank.
But above-mentioned circulation of drilling fluid mode one has the following problems:
1. bulky grain solid formation easily blocks fine pressure control choke manifold in drilling fluid, the fine controlled pressure drilling of next stage is influenced
Construction；2. occupying fine control pressure line for a long time, throttling to fine pressure control, it is larger to control line losses, and also will increase normal brill
Cost during well；3. circulation of drilling fluid channel becomes smaller during normal drilling well, the drilling parameters such as pump pressure in drilling process are influenced；
Above-mentioned circulation of drilling fluid mode two has the following problems:
1. drilling team's choke manifold belongs to well control equipment, occupies there is greatly well control safety risk for a long time；2. drilling fluid
Bulky grain solid formation easily blocks drilling team's choke manifold, influences the normal wellbore construction of next stage；3. influencing in normal drilling process
The drilling parameters such as pump pressure.
Therefore it provides a kind of be switched fast part flow arrangement for fine controlled pressure drilling, so that circulation of drilling fluid channel is more
For safety it is unobstructed be those skilled in the art's urgent need to resolve the problem of.
Summary of the invention
In view of this, being switched fast part flow arrangement for fine controlled pressure drilling the present invention provides a kind of, it is intended at least
One of above-mentioned technical problem in the prior art is solved to a certain extent.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of part flow arrangement that is switched fast for fine controlled pressure drilling, including rotating blowout preventer, liquid-operated flat valve and control
Pressure pipeline further includes part flow arrangement ontology, and there is the part flow arrangement ontology the first opening and two second symmetrically to open
Mouthful, the control pressure line is mounted in first opening, and the rotating blowout preventer and the liquid-operated flat valve are separately mounted to
In two second openings.
Further, the part flow arrangement ontology includes tee pipe fitting and flap type；The tee pipe fitting has one and enters
Mouth and two outlets, the flap type inside form through type channel；The entrance and through type one end of the channel flange connect
It connects, the through type channel other end is connected with the control pressure line by flange group；Two it is described outlet respectively with it is described
Rotating blowout preventer, the liquid-operated flat valve flanged joint.
Further, the flange group includes flange gasket, first flange and second flange, and the flange gasket is arranged described
Between first flange and the second flange, the first flange and the second flange are fastened by bolts together.
Further, the tee pipe fitting is carbon steel material.
By taking above scheme, the beneficial effects of the present invention are:
By adding part flow arrangement ontology between rotating blowout preventer and liquid-operated flat valve, fine controlled pressure drilling mistake is realized
Fine controlled pressure drilling and normal drilling state are switched fast in journey, so that circulation of drilling fluid channel is safer unobstructed.
