Abstract:
The present invention relates to the technical field of rotary steerable drilling, particularly to an apparatus for testing the function and performance of a rotary steerable tool in a horizontal or inclined state. The apparatus comprises a rotary steerable tool testing bench configured to provide a horizontal state and an inclined state for a rotary steerable tool so as to simulate a horizontal drilling state or a directional drilling state on the ground; and a rotary steerable tool function and performance testing unit disposed on the rotary steerable tool testing bench to test the function and performance of the rotary steerable tool in the horizontal drilling state or the directional drilling state. The apparatus in the present invention can test the function and performance of a push-the-bit rotary steerable tool under horizontal and inclined conditions on the ground in a lab.

Claim (Index 3):
The apparatus for testing the function and performance of a rotary steerable tool in a horizontal or inclined state according to  claim 2 , wherein, the testing assembly ( 2 ) for force measurement of ribs and force signal feedback comprises rotary steerable tool ribs ( 42 ), universal load-bearing feet ( 41 ), adjusting studs ( 40 ), pushing force sensors ( 40 . 1 ), connectors ( 44 ), and top beams ( 38 ); the rotary steerable tool ribs ( 42 ) are always in contact with the universal load-bearing feet ( 41 ) during operation, the universal load-bearing feet ( 41 ) are connected with the adjusting studs ( 40 ) via threads, the adjusting studs ( 40 ) are connected with the pushing force sensors ( 40 . 1 ) via threads, the upper ends of the pushing force sensors ( 40 . 1 ) are connected with the connectors ( 44 ), the connectors ( 44 ) are connected with the top beams ( 38 ), and the feet ( 38 . 1 ) on both sides of each of the top beams ( 38 ) are placed in lower slots of tension-bearing cover plates ( 42 ) and outer slots of tension-bearing bases ( 43 ); the tension-bearing cover plates ( 42 ) are connected with the tension-bearing bases ( 43 ); and an action-reaction force equilibrium is established against the pushing force of the ribs  42  via the universal load-bearing feet ( 41 ), the adjusting studs ( 40 ), the connectors ( 44 ), the top beams ( 38 ), the tension-bearing cover plates ( 42 ), and the tension-bearing bases ( 43 ), so that the pushing force of the ribs can be measured.
