Domestic big oil company and institutes all drop into great amount of manpower and fund to rotary steerable drilling system at present; In order to guarantee the successful property of system development; Reduce unnecessary loss; Be necessary to verify through the motion state of simulation subsurface equipment whether the parameters of rotary steerable drilling system stable platform satisfies performance index.And development stable platform testing experiment stand is exactly the ground special test system that designs for the underground work situation of simulating the rotary steerable drilling system stable platform.When the test-bed level or when vertically placing; Motor drives stable platform simulation drill collar rotates to specify rotating speed with the simulation turbine; Test macro can be with corner, the rotating speed of stable platform; The parameters such as inclination angle of the corner of output shaft, rotating speed, output torque and test-bed are handled and storage through measuring.According to resulting parameter its performance is analyzed then, so that whether algorithm is correct in the checking stable platform, whether each sensor is sensitive correct and whether circuit is in proper working order, thereby in time finds and correct the problem that exists in the stable platform.
Summary of the invention
The object of the present invention is to provide a kind of proving installation that is used to check the rotary steerable drilling system stable platform, the environmental baseline that can completely reasonably simulate stable platform in underground work.
The objective of the invention is to realize through following technical scheme:
A kind of proving installation of stable platform comprises and measures stage unit and rotating basis unit.It is characterized in that: described stage unit is truss-frame structure or framed structure; The rotating basis unit comprises hydraulic pressure tilt cylinder or power driven system, and connects mutually with stage unit through rotary main shaft.
Described measurement stand unit pack is drawn together servo drive motor, load system and measuring system, and fixed connection is on stand.Described servo drive motor connects with stable platform on being placed on platform through shaft coupling or through the belt pulley transmission mutually.Described load system is one or more torque generators.Described measuring system comprises accelerometer, absolute type code-disc and torque gauge, is installed in respectively on the output shaft and testboard bay of stable platform.Described base unit comprises hydraulic pressure or electronic perpendicular system and around the rotation system of center axle rotation.
The beneficial effect that device for testing stable platform of the present invention has is that the measurement stage unit adopts no magnetic or non-ferromagnetic material manufacturing, can reduce the interference to stable platform effectively, thereby guarantees precision of test result; Measure stand and offer the required generator speed of stable platform, drill collar rotating speed and load torque, the working condition under can simulation well; Measuring system can obtain corner, the rotating speed of stable platform, the parameters such as inclination angle of the corner of output shaft, rotating speed, output torque and test-bed, thereby the performance parameter of checking stable platform.The rotating basis unit can implementation platform in the perpendicular of space freely swing and around freely the rotating of center axis, thereby the variation of simulation hole deviation and direction parameter, and whether the checking stable platform is stablized and is worked exactly.
