Description

Technical Field

[0001] The invention relates to the technical field of drilling simulation, in particular to a visual drilling simulation test platform. Background Art

[0002] The work of drilling holes in the ground using mechanical equipment or manpower is called drilling. Drilling is usually divided into geological survey or exploration drilling, hydrogeological drilling, water well or engineering geological drilling, geothermal drilling, oil drilling, coalfield drilling, mine drilling, construction ground drilling, etc.

[0003] Simulation testing refers to a virtual and physical testing method for drilling equipment. When the drilling equipment is physically tested, physical information such as changes in the surrounding soil during the drilling process and the actual situation of the drill bit can be obtained. After the test is completed, this type of information is summarized, and then the situation during the drilling process can be sorted out to facilitate adjustment and maintenance of the equipment before formal drilling. However, in the current simulation testing work, most of the drill bit pressure is indirectly monitored by inputting the actual size of the oil pressure, and the pressure condition of the drill bit cannot be directly detected conveniently. The pressure value obtained by calculation often has a certain deviation. In the process of mining, different drill bits need to be used for drilling according to different soil conditions. In order to ensure the matching of the drill bit, multiple tests are often performed to improve the accuracy, which affects the overall testing efficiency. In this regard, the present invention provides a visual drilling simulation test platform to solve the above problems. Summary of the invention

After the plug-in block 308 is plugged into the inner side of the corresponding plug-in groove 309, the two limit baffles 307 can be spliced ​​into a structure, which is convenient for covering the bottom opening of the limit groove 305, so that the limit block 304 will not fall out therefrom, thereby playing a role of blocking and limiting.

[0041] In addition, the bottom of the fixing groove 312 is open, and the fixing groove 312 is provided for the corresponding fixing plate 311 to be inserted. The fixing plate 311 is connected to the outer side of the drilling rig output shaft 301 through bolts, so that the fixing plate 311 is inserted into the inner side of the corresponding fixing groove 312 and then connected and positioned through bolts.

The nozzle 506 passes through the outside of the first visible pipe 501 or the second visible pipe 503 and extends to the inside of the corresponding retaining box 507, so that the nozzle 506 can humidify the simulated soil inside the first visible pipe 501 and the second visible pipe 503 through the retaining box 507.

[0046] At the same time, the probe of the humidity sensor 508 passes through the outside of the first visual pipe 501 or the second visual pipe 503 and extends to the inside, so that the humidity sensor 508 can monitor the humidity inside through the probe, and the internal extension length of the probe does not exceed the outside of the baffle box 507. Specifically, the diameter of the drill bit body 306 and the drilling rig output shaft 301 is smaller than the inner diameter of the first visual pipe 501 and the second visual pipe 503, and is located on the outside of the baffle box 507. At the same time, the front side of the first visual pipe 501 or the second visual pipe 503 is concave, so that the front side can be closer to the drill bit body 306 and the drilling rig output shaft 301, so that the internal situation can be more conveniently displayed without affecting the drilling simulation.

[0047] In this embodiment, the wellhead protection assembly 600 is a structure used to provide certain splash protection for the wellhead.

The inner diameter of the guide frame 708 is larger than the inner diameter of the connecting hole and is located at the bottom of the connecting hole, so that the material inside the first visible pipe 501 can pass through the guide frame 708 into the inside of the discharge pipe 703 and then be discharged.

[0053] In addition, the two corresponding guide blocks 709 are symmetrically distributed front to back, and the guide holes 710 are provided for the corresponding guide blocks 709 to be plugged in and slide. Specifically, the center of the guide hole 710 is the same as the center of the rotating shaft 705 on the same side, so that the guide block 709 can be driven by the blocking plate 707 to move normally on the inner side of the guide hole 710, and can play a guiding and limiting role.

[0055] The working principle of the above embodiment is:

[0056] (1) Before the test work begins, according to the sampling information of the actual land, soil, stones, gravel and other materials are filled in layers between the first visual pipe 501 and the second visual pipe 503 to simulate the soil information in the actual drilling process, and the position and thickness of each material are changed according to actual needs. After the filling work is completed, water is transported to the inside of the first visual pipe 501 and the second visual pipe 503 through the arc pipe 505 and the nozzle 506, and the humidity of the surrounding soil is monitored under the action of the humidity sensor 508 to improve the authenticity of the actual simulation. The loading of the simulation test scene can be completed, and the drilling mechanism 204 is started to make The drill output shaft 301 drives the movable rod 303 to rotate normally through the cooperation between the limit groove 305 and the limit block 304, and then drives the drill bit body 306 to rotate. Under the action of the movable groove 302, the movable rod 303 can have space to move up and down, so that when the drill bit body 306 enters the interior of the second visible pipe 503 for drilling, the stone and soil can abut against the bottom of the drill bit body 306 and apply an upward reaction force to the drill bit body 306, so that the pressure sensor 310 can be pressed normally, so that the actual pressure condition and data of the drill bit body 306 can be directly monitored.

[0057] (2) During the drilling process, the servo motor 609 is started to drive the active bevel gear 610 to rotate, so that the driven bevel gear 608 rotates and drives the drive shaft 607 to rotate, thereby rotating the corresponding rotating rod 604. Under the meshing transmission action of the transmission gear 605, the two opening and closing plates 602 can rotate in opposite directions, so that the opening and closing plates 602 can move to the top of the fixed cylinder 601 to block the debris generated by drilling. The front recessed parts of the first visual pipe 501 and the second visual pipe 503 can more intuitively facilitate external staff to check the rotation and appearance of the drill bit body 306, and then judge whether the drill bit is The adaptability of the main body 306 to this type of soil is determined after the drilling simulation test. The drill bit main body 306 is moved out from the inner side of the second visible pipe 503, and the collection box is placed at the bottom of the discharge pipe 703. The hydraulic cylinder 712 is started to push the first connecting plate 713 to move downward, and then the corresponding connecting rod 715 is driven to move through the second connecting plate 714, so that it can push the corresponding third connecting plate 716 to rotate downward, so that the blocking plate 707 can be rotated to open, and the rotation angle is limited under the cooperation of the guide hole 710 and the guide block 709, so as to control the discharge rate and facilitate the subsequent post-processing work.

[0058] Compared with the prior art, the visual drilling simulation test platform, through the use of the drill bit assembly 300, can facilitate the staff to directly observe the pressure condition of the drill bit, reduce the steps of data calculation, so that the obtained data can be closer to the actual use condition, and facilitate the staff to summarize the obtained data and adjust the parameters of the drill bit more accurately. Under the action of the land simulation assembly 500, various land conditions can be simulated for drilling testing, and it is convenient for the staff to observe the changes in the ground during the drilling process, and it is also convenient to display the appearance and mining conditions of the drill bit, so that the outside staff can grasp more data information. Through the wellhead protection assembly 600, the debris splashed during the drilling process can be blocked to a certain extent, which plays a certain protective role in the external test environment and facilitates the subsequent cleaning work. Under the action of the emptying assembly 700, the internal soil simulation material can be effectively discharged after the test work is completed, so that the follow-up work after the test can be conveniently carried out, which solves the problem that the existing drilling simulation test platform mostly obtains the pressure value of the drill bit through other data or virtual data during the actual test, resulting in the need for repeated tests, which affects the test efficiency.

[0059] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
