Description
Technical field
The utility model belongs to petroleum engineering well drilling equipment technology field, relates to a kind of device of simulated condition, particularly relates to a kind of oil-well rig drilling condition analogue means.
Background technology
In oil-well rig drilling process, due to the difference of drilling depth and beneath geology, the friction of drill bit and the borehole wall, these factors of the elastic deformation of drilling rod cause the complicacy of operating mode in actual well drilled process, also do not have effective method can simulate the complex working condition of down-hole in oil-well rig drilling process at present.
Utility model content
For overcoming above-mentioned deficiency, the utility model object there is provided a kind of complex working condition that can simulate in oil-well rig drilling process, and structure simple, easy to operate, adaptable oil-well rig drilling condition analogue means.
Scheme of the present utility model is as follows: a kind of oil-well rig drilling condition analogue means, and this device mainly comprises main body rack, motor-driven mechanism, drill string simulation mechanism; Motor-driven mechanism comprises main variable-frequency motor and servomotor, is arranged at top and the bottom of main body rack respectively; Connected by drill string simulation mechanism between two motors.
Described drill string simulation mechanism part comprises top mass, wire rope and lower mass block, and top mass and main transformer frequently electric machine main shaft are connected, and lower mass block is connected with servomotor spindle.
Described main body rack entirety is in " door " font; Described main body rack also comprises railroad; Described lower mass block is fixed on railroad.
Described railroad comprises installing plate and slide rail; Described slide rail is connected with main body rack; The slide block arranged under described installing plate can move up and down along slide rail; Described lower mass block is fixing on a mounting board by support.
The utility model structure is simple, easy to operate, strong adaptability.The utility model dynamic modeling method simplifies actual drill string rotating system (being made up of rotating disk, drilling rod, drill collar and drill bit), rotating disk, drilling rod, drill collar and drill bit can be equivalent to top mass, spring steel wire rope, lower mass block, be used for simulating the rotation of drilling rod by main variable-frequency motor, servomotor be used for simulate drill bit creep in geology operating mode, the working conditions change of oil-well rig drilling well can be simulated, i.e. the change of the dynamics different conditions of the change of rotary speed, drill string rotating, down-hole friction force and other viscosity resistances.
