Description
Technical field
The present invention relates to oil-gas drilling engineering technology downhole orientation well drilling tool apparatus field, particularly a kind of angle
The controllable rotary steerable tool of degree.
Background technology
Rotary steerable drilling system (Rotary Steerable Systems, abbreviation RSS) be when drill string rotating is crept into,
With a kind of guide type well system for boring completion guide function in real time, current international rotary steerable drilling system, according to it
Guidance mode can be divided into two kinds of pushing type (Push the Bit) and directional type (Point the Bit).
In recent years, as domestic and international most of oil field subsequently enters development late stage, and new exploratory area major part is all in special
Environment, increases exploration and development difficulty and cost.In order to improve the rate of oil and gas recovery, reduces cost, ultradeep well, highly difficult orientation
The special well technologies such as well, cluster well, horizontal well, extended reach well, multihole well and three-dimensional multi target well occur and are subject in succession
Pay attention to extensively, and can guide or control well by predetermined well track (geometry guiding) or predetermined formation at target locations (geology
It is oriented to) the rotary steerable drilling technology of drilling turns into and is drilled to the key technology of these highly difficult complex structural wells.
Additionally, the exploitation of the unconventional petroleum resources such as shale gas needs RSS technologies.In order to reduce shale gas development cost, obtain
Earning rate higher is obtained, cluster horizontal well has turned into the main drilling mode of shale gas exploitation.In cluster horizontal well drillng operation
In, in order to accelerate bit speed, extend horizontal segment displacement, single well productivity is improved, RSS is essential in just being developed into shale gas
Technical equipment.
Therefore a kind of controllable Novel rotary steering tool of angle is studied significant.
The content of the invention
In order to improve drilling efficiency, realize that downhole drill angle is controlled, the invention provides a kind of controllable new of angle
Rotary steerable tool, makes to adjust drilling well angle at any time in drilling engineering.
The purpose of the present invention is realized by embodiments below：

Shell is constituted, and slidable piston mechanism can be controlled two positions by controlling the size of flow, position connect fluid with
Biasing executing agency, realizes another position buffer fluid of directed drilling into biasing mechanism chamber, realizes vertical drilling.
In some embodiments, the piston in angle control assembly can be real under the collective effect of upper and lower two flow valves
Now move back and forth, so as to realize that multi-angle taps the reciprocating motion of ring, it is a device for pyramidal structure that multi-angle taps ring, is led to
Cross and realize the controllable of angle with the co- controlling of deflection ring.When deflection ring is moved, deflection ring can promote inner sleeve and outer sleeve
Engagement, realizes that biasing mandrel rotates jointly with biasing shell, is now non-guide drilling state；When hydraulic pressure becomes hour, in pressure
In the presence of spring, realize that biasing mandrel is separated with biasing shell, be now steerable drilling state.
In some embodiments, slidably piston passes through the locating slot set on piston and shop bolt in hydraulic regulation
Moved back and forth with realization under the collective effect of spring, by the through hole on piston and the shape each other of the through hole of biasing mandrel
State is realized biasing actuating mechanism controls to biasing mechanism.
Deflection ring in some embodiments, inner sleeve, outer sleeve is provided with key with keyway with the flexible mandrel of deflection
Structure, so that real bias mandrel and bias the transmission of shell circumference moment of torsion and slide axially.
In some embodiments, piston is provided with an abutment sleeve in end when being moved back and forth in biasing mandrel.
The beneficial effects of the invention are as follows：By control valve, the reciprocating motion to piston in angle controller, control are realized
Drilling well angle processed, the control of the reciprocating motion co- controlling drilling state by controlling clutch and control piston, realizes brill
The switching of well mode, double control improves the security of drilling well, while improve drilling efficiency.
