Abstract
The utility model discloses a multifunctional well drilling mechanism with torque feedback. The multifunctional well drilling mechanism comprises a drill rod, wherein the upper end of the drill rod is provided with a rotary table with gear teeth; the rotary table is meshed with a chain wheel with gear teeth; the chain wheel is connected with a reduction box output transmission shaft through a chain; a reduction box is connected with an electric motor. The multifunctional well drilling mechanism overcomes the problem of drill bit clamping appearing during existing well drilling process, can be used for changing the rotating speed of the drill rod in real time at different geologies, and provides a well drilling mechanism with different torques according to the hardness of geological stratification.
Description
Technical field
The utility model relates to a kind of oil and gas well drilling mechanism, specifically, is a kind of have torque-feedback and adjustable multifunction drilling machine structure of speed.
Background technology
In oil and gas well drilling process, usually can there is because of the reason of geological stratification hardness bit freezing phenomenon, cause equipment to be damaged, not only affected drilling efficiency, increased the cost of drilling well simultaneously.In addition because geological stratification can change along with the degree of depth, require drilling rod must tackle the geological stratification under different hardness different densities in drilling process, this has higher requirement to drilling process.
Summary of the invention
To be solved in the utility model is the bit freezing problem of the appearance in existing drilling process, and providing a kind of can change rod rotation speed in real time according to different geology, and the drilling well mechanism of different moments of torsion is provided according to geological stratification hardness.
In order to solve the problems of the technologies described above, device of the present utility model is achieved by following technical scheme: a kind of multifunction drilling machine structure with torque-feedback, comprise drilling rod, the upper end of described drilling rod is provided with the rotating disk with the gear teeth, described rotating disk by the gear teeth and sprocket wheel phase tooth with the gear teeth and, described sprocket wheel is connected with reductor take-off (propeller) shaft by chain, and described reductor is connected with motor.
The upper end of described drilling rod is square structure, the square hole arranging for being inserted into rotating disk middle part.
On described rotating disk, be also provided with torque sensor, described sensor is subject to force signal by drilling rod, passes to controller, and described controller is controlled frequency converter according to feedback signal and regulated motor speed, so that rod rotation speed adapts to different geological stratifications.
The beneficial effects of the utility model are:
The utility model is simple in structure, and scheme is reliable, easy to operate, can according to different geology, regulate in real time the rotating speed of drilling rod, has avoided like this appearance of bit freezing phenomenon.In addition, according to different geological stratifications, regulate rod rotation speed, can save certain energy, reduce drilling cost.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1 to Figure 2
,a kind of multifunction drilling machine structure with torque-feedback, comprise drilling rod 1, the upper end of the utility model drilling rod is square structure, is provided with the rotating disk 2 with the gear teeth in the upper end of described drilling rod 1, the middle part of described rotating disk 2 is provided with square hole, for square drilling rod upper end is inserted wherein; Described rotating disk 2 be by the gear teeth and sprocket wheel 3 phase teeth with the gear teeth and, described sprocket wheel 3 is connected with the take-off (propeller) shaft of reductor 5 by chain 4, described reductor 5 is connected with motor 6; The utility model is also provided with torque sensor 7 on described rotating disk, described sensor 7 is subject to force signal by drilling rod 1, pass to controller 8, described controller 8 controls according to feedback signal the rotating speed rotating speed that frequency converter 9 regulates motor 6, so that the rotating speed of drilling rod 1 adapts to the needs of different geological stratifications.
Operating principle of the present utility model is: torque sensor is fixed on rotating disk, be used for measuring drilling rod Moment size in drilling process, the signal feedback of torque sensor is to controller, controller can be sent out control signal to frequency converter according to feedback signal and set model, frequency converter regulates motor speed, so that rod rotation speed adapts to different geological stratifications; Controller is control core, and user can set drilling model according to the geology result of exploration in advance, and pattern and torque sensor feedack that controller can be set according to user are adjusted, and in particular cases can operate drilling rod reversion, and flexible operation is reliable.
Although preferred embodiment of the present utility model is described with preferred embodiment by reference to the accompanying drawings above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing from the scope situation that the utility model aim and claim protect; can also make the concrete conversion of a lot of forms, within these all belong to protection domain of the present utility model.
