Description
Technical field
The present invention relates to field of oil drilling more particularly to drilling guidance tools, and in particular to a kind of rotary steerable tool
Hydraulic pressure unit oiling device.
Background technique
Currently, rotary steerable drilling technology is the various Advanced Drilling Technologies developed outside Now Domestic and has much in technique prominent
The technology of broken property and strategic importance, has just started the revolution of a directed-drilling technique since the 1990s occurs.
Before the appearance of rotary steerable drilling technology, mostly uses and implemented by the slide-and-guide well system of mud motor driving
Steerable drilling, slide-and-guide well system drill string during steerable drilling does not rotate, but slides axially along the borehole wall, and pass through
Slide-and-guide tool changes hole angle and the azimuth of wellbore, to control well track.Existing for slide-and-guide well system
Problem has sliding difficult, needs to keep orienting, the cleannes of wellbore are poor, and drilling speed is lower, it is possible to create buckling and self-locking
Deng the progress of the presence influence drilling of these problems and the normal operation of drilling equipment.
And rotary steerable drilling system keeps the rotary drilling of wellbore direction in drilling process, with slide-and-guide well system
It compares, there is frictional resistance and turns round that resistance is small, drilling speed is high, at low cost, well construction period is short, the smooth easy-regulating of well track and can extend level
The advantages such as segment length.
It is determined by the unique method of operation of rotary steerable tool, perfect hydraulic list is configured in rotary steerable tool
Member carries out the equalizing and buffering of load and impact, while in certain links, hydraulic pressure unit will also have both the effect of lubrication, heat dissipation, therefore
And to carry out imperfectly hydraulic pressure unit design.
In the hydraulic pressure unit of rotary steerable tool, working chamber need to fill full hydraulic oil, so that hydraulic oil can be played sufficiently
The effect of lubrication, balance pressure.And under the high temperature and high pressure environment of underground, in working chamber, the volume change of hydraulic oil is smaller, but
The volume of air then by temperature, pressure influence and change clearly, if the Oil feeding process into the working chamber of hydraulic pressure unit
In, it cannot sufficiently exclude inherently to bring a certain amount of air in the air being mingled in hydraulic oil or Oil feeding process into, cause
Residual air is excessive in oil-filled rear chamber.In this case, if after the expansion of air heat or because pressure change leads to volume
Change the normal operation all by severe hydraulic unit, and then entire rotary steerable tool is caused to can not work normally.
Therefore suitable oiling device and oil-extended process are that those skilled in the art urgently pay close attention to.
The oil-filled mode of conventional petroleum downhole instrument is immersion type oiling, and this mode utilizes the principle of negative pressure of vacuum pump, empty
Gas is under condition of negative pressure, volume expansion, floats to the exclusion of lubricating cup top.Remain in the air in oil-filled chamber in part micro gap,
It then needs to beat repeatedly, shake instrument, be allowed to be detached from the constraint of mucosa surface tension, float, discharge, the oil filling method efficiency is very
It is low, and during tapping, shaking, instrument can be caused to impact, rotary steerable tool is arranged to the impact and shake born
The direction of dynamic loading all has certain requirements, irregular to tap, shake the stability that will affect instrument interior structure.
Finally, due to some instrument interior structures are complicated, it may be by beaing even if there are the bubbles adhered in a some holes, slot, gap
It is also difficult to disengage it from vibration.It should be noted that above content belongs to the technology category of cognition of inventor, not necessarily structure
At the prior art.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of rotary steerable tool hydraulic pressure unit oiling device, passes through and configures
It supports realization to vacuumize, recycle and Synchronous Heating oil injection operation, while dedicated oil-filled fixture is set, to be adjusted in Oil feeding process
The placing direction of rotary steerable tool hydraulic pressure unit to reduce the air residual in the oil-filled chamber in hydraulic pressure unit, and improves
The working efficiency of oiling.
The technical scheme adopted by the invention is as follows:
A kind of rotary steerable tool hydraulic pressure unit oiling device, comprising:
