Rotary steerable drilling technology is broadly divided into modulation system rotary steering drilling tool and not rotary sleeve formula rotary steering
Drilling tool.Using not rotary sleeve formula guide drilling tool, need to ensure not rotary sleeve and borehole wall circumferential position relatively quiet
Only, just can guarantee that the tool-face position of rotary steering drilling tool is stable.However, in drilling process, due to underground power drilling
Tool can produce reaction torque to well drilling pipe column, so that well drilling pipe column is twisted, cause tool-face position stablize, it is necessary to constantly real
When adjust tool-face, cause ground handling operator's workload increase, work efficiency drop.For overcoming tool-face position in drilling process
Put cannot be stable problem, the present invention designs a kind of drilling tool face stabilizer, it is ensured that tool-face position is stable.
Content of the invention
The purpose of the present invention is：For a kind of tool-face position is stable in rotary steering technology, spudder of spy's offer
Tool face stabilizer.
In order to achieve the above object, the present invention is employed the following technical solutions：A kind of drilling tool face stabilizer, is connect from above
Head, spring, housing, empty boasting, piston, connecting rod, steady wheel, wheel seat and stabilizer composition；Its architectural feature is：Top connection top and
Rotary steerable tool screwed connection, stabilizer bottom and mud motor screwed connection；Housing upper and top connection screw thread connect
Connect, lower housing portion and with stabilizer screwed connection, housing cavity arrange a step；Spring is pacified on housing cavity step
During dress, spring is in compressive state；Empty boasting is arranged on housing cavity, and empty boasting top and housing cavity contact surface are close with sealing ring
Envelope, empty boasting bottom and stabilizer lumen contact face are sealed with sealing ring；Four centralizer wings are provided with outside stabilizer, in centralizer wing
Setting is fluted, and stabilizer inner chamber is provided with a step, arranges four piston holes and connect with the groove in centralizer wing on step；Even
Bar one end and piston hinge, the other end and wheel seat are hinged；Steady wheel is provided centrally with pin shaft hole, cylindrical on to be provided with zigzag convex
Rise；Wheel seat middle setting has rectangular through-hole, and steady wheel is inserted in wheel seat rectangular through-hole, and steady wheel and wheel seat are connected with bearing pin；Four
Installed in four piston in the holes of stabilizer, four wheel seats are arranged in the groove of four centralizer wings of stabilizer individual piston, wheel seat
The centralizer wing of one end and stabilizer is hinged；Oil filler point is provided with housing, injection liquid in the annular space that empty boasting and housing are formed
Force feed.
The invention has the beneficial effects as follows：(1) effectively tool-face position can be carried out stablizing, prevents tool-face sideslip；(2) no
Impact well drilling pipe column axial feeding；(3) it is controlled using drilling fluid, extra power need not be configured；(4) pure mechanic structure, behaviour
Make reliable.
