In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
In a first aspect, the embodiment of the present invention provides a simulated wellbore device, as shown in fig. 1, the simulated wellbore device 1 includes a simulated wellbore 101, a plate-shaped support 102, and one end of the simulated wellbore is connected to the plate-shaped support through a rotating member; the rotating member includes: an input line in vertical communication with the end of the simulated wellbore; the support is fixedly arranged on the plate-shaped support and comprises a support bottom and two fixing plates which are oppositely arranged on the support bottom and are used for fixing the input pipeline. A derrick 103 vertically connected to the right side wall of the plate bracket 102. A motor 104 and a speed reducer 105 connected by a coupling are provided on the right plate surface of the plate bracket 102. And a first pulley 106 connected to a drive shaft of the reduction gear 105. And a second pulley 107 located directly above first pulley 106 and vertically connected to mast 103 by a transverse link. A wire rope 108 having one end fixed to the first pulley 106 and passing through the first pulley 106 and the second pulley 107 in this order to connect the other end to the simulated wellbore 101. And a power controller 109 for controlling the operation of the motor 104.
The following description is given of the working principle of the simulated wellbore apparatus 1 provided by the embodiment of the present invention:
when the simulated shaft 101 needs to rotate by a preset angle, an operator controls the power controller 109, the power controller 109 sends a control command to the motor 104 electrically connected with the power controller, the motor 104 receives and processes the control command, then the power is transmitted to the speed reducer through the coupling according to the control command, the speed reducer transmits the power to the first pulley 106 through the transmission shaft, the first pulley 106 rotates, the length of a part of the steel cable 108 wound on the first pulley 106 is changed by the rotation of the steel cable 108 along with the rotation of the first pulley 106, and the part of the steel cable 108 connected with the simulated shaft 101 bypasses the second pulley 107 and pulls the simulated shaft 101 to rotate until the simulated shaft 101 rotates to the preset angle. In order to facilitate the arrangement of the second pulley 107 and to avoid the simulated borehole 101 from rotating to hit the motor 104 and the reducer 105 arranged on the plate bracket 102, a derrick 103 is arranged vertically connected to the right side wall of the plate bracket 102.
It should be noted that the simulated wellbore 101 can rotate along a vertical plane, and the rotation angle can be 0 ° and 90 °, that is, the simulated wellbore 101 can simulate a slant well with different inclinations on the premise that it can simulate a horizontal well and a vertical well. The simulation shaft 101 is made of transparent organic glass material, and scales are arranged on the outer wall of the simulation shaft 101, so that an operator can observe the form of the oil-gas-water three-phase fluid in the simulation shaft 101 conveniently, and the oil-gas-water three-phase fluid in the simulation shaft 101 cannot leak in the rotating process of the simulation shaft 101. The lower end of the simulated shaft 101 is also communicated with a pipeline for inputting and outputting three-phase fluid, and the pipeline is provided with a valve so as to control the three-phase fluid to be input into the simulated shaft 101 or output from the simulated shaft 101.
The power controller 109 can send control commands of starting, stopping, accelerating, decelerating, forward rotating, reverse rotating, and rotating angles to the motor 104, so as to control the simulated wellbore 101 to rotate in different directions and at different speeds, and rotate to a preset angle. To facilitate remote control by an operator, a remote control may also be provided that can be used to remotely program the power controller 109.
The speed reducer may reduce the speed of the motor 104 to ensure smooth power transmission to the first pulley 106, thereby allowing the simulated wellbore 101 to rotate smoothly.
Based on the above, the simulated wellbore device 1 provided by the embodiment of the invention can be used for conveniently simulating an inclined shaft with a predetermined inclination by rotatably arranging the simulated wellbore 101 in the middle of the plate-shaped bracket 102 and matching the steel cable 108, the motor 104, the speed reducer 105 and the first pulley 106 to realize rotation. By arranging the power controller 109, an operator can conveniently set the forward rotation, the backward rotation and the rotation angle, and the transmission power of the motor 104 and the speed reducer 105 is controlled, so that the simulated shaft 101 rotates to a preset angle. By arranging the second pulley 107, the force on the steel cable 108 can fully act on the simulated borehole 101, the simulated borehole 101 can not be pulled up, and electric energy can be saved. Therefore, the simulated wellbore device 1 provided by the embodiment of the invention can simulate inclined wells with different slopes on the premise of simulating horizontal wells and vertical wells, and has a simple structure.
Dynamic sealing is realized by arranging a sealing ring between the input pipeline and the simulated well bore 101. The simulated wellbore 101 can rotate around the input pipeline, leakage of the three-phase fluid can be prevented during rotation of the simulated wellbore 101 by arranging a sealing ring, and the input pipeline is required to ensure that the three-phase fluid can normally circulate in the simulated wellbore 101.
As shown in fig. 1, the apparatus provided by the embodiment of the present invention further includes a wheel disc 111 having a central angle of 90 °; one horizontal side wall of the wheel disc 111 is fixed on the plate-shaped bracket 102, and the axis of the rotating shaft passes through the center of the wheel disc 111; the wheel disc 111 is provided with scales of 0-90 degrees. The wheel disc 111 is arranged, and the axis of the rotating shaft penetrates through the center of the wheel disc 111, so that an operator can conveniently observe the rotating angle of the simulated shaft 101. Wherein, the scales on the wheel disc 111 are arranged at intervals of 10 degrees, so that the operator can clearly observe the rotating angle of the simulated shaft 101.
In order to prevent the simulated wellbore 101 from being positioned due to the fracture of the steel cable 108, the simulated wellbore 101 can be fixedly connected with the wheel 111 when the simulated wellbore 101 is rotated to a certain angle. Preferably, the simulated wellbore apparatus 1 further comprises a wellbore steel frame 112; the simulated shaft 101 is fixed on a shaft steel frame 112, and the shaft steel frame 112 is provided with a first through hole; a plurality of second through holes opposite to the first through holes are uniformly formed in the periphery of the plate surface of the wheel disc 111; the shaft steel frame 112 and the wheel disc 111 are fixedly connected by penetrating the first through hole and the second through hole by using the rod-shaped fixing member 113, so as to realize the positioning of the simulated shaft 101. The simple arrangement is convenient for an operator to accurately observe the angle on the wheel disc 111 corresponding to the simulated wellbore 101.
It should be noted that, after the wellbore steel 112 is set, the wireline 108 may be directly fixed to the wellbore steel 112.
In order to enable the disc 111 to suitably bear the weight of the simulated wellbore 101, the radius of the disc 111 is set to be greater than one sixth of the length of the simulated wellbore 101.
When the simulated shaft 101 rotates to 90 degrees, the simulated shaft cannot be stopped immediately due to inertia, and in order to avoid the simulated shaft 101 from directly impacting the derrick 103, as shown in fig. 1, a spring impactor 114 positioned above the plate-shaped bracket 102 is vertically arranged on the derrick 103; the height between the spring impactor 114 and the plate bracket 102 is less than the length of the simulated wellbore 101. The height of the spring impactor 114 is set so that the simulated wellbore 101 can impact the spring impactor 114 to provide a cushioning effect.
