Description

Technical Field

[0001] The invention belongs to the field of formation parameter determination in geotechnical engineering exploration technology, and specifically relates to a formation occurrence determination device in an exploration well and a use method thereof. Background Art

[0002] With the development of society, various types of construction projects have sprung up everywhere. According to relevant laws and regulations, geotechnical engineering surveys must be carried out before design and construction of various types of construction projects. In the requirements of relevant specifications for geotechnical engineering surveys, exploration wells must be excavated during loess field exploration, and geotechnical information such as stratum properties and geological parameters must be described and determined by collecting geotechnical samples in the well to comprehensively evaluate the impact of the site's rock and soil strata on the foundation of the proposed building. In recent years, with the continuous standardization of engineering construction processes, the requirements for geotechnical engineering surveys for engineering projects have become increasingly stringent, especially with the continuous updating of relevant industry specifications and standards, which puts forward higher requirements for the description and recording of rock and soil strata on the wall of the exploration well in geotechnical field exploration: such as: ① The described and recorded stratum occurrence must be true and accurate; ② The described and recorded stratum occurrence must be continuous and comprehensive.

[0003] At present, there are two main methods for describing and recording the occurrence of strata on the wall of exploration wells during geotechnical engineering investigations: the first method is for geotechnical technicians to personally go down into an exploration well with a vertical depth of 20m to 30m, observe the strata with the naked eye, and record them; the second method is for mechanical equipment to take rock and soil samples at regular depths in the exploration well and send them to the ground, whereupon ground technicians describe and record the occurrence of the strata based on the rock and soil samples.

[0004] There are technical problems with the main methods of describing and recording the occurrence of strata on the wall of the exploration well during the current geotechnical engineering investigation on-site: the first method is that geotechnical technicians personally go down to the exploration well to observe. Although geotechnical technicians personally go down to the exploration well and observe the rock and soil conditions of the well wall with their naked eyes, there are huge safety hazards. Once the exploration well collapses, personnel will be buried in the exploration well with a depth of 20m to 30m. Rescue is very difficult, and there is a great possibility of a production safety accident with the death of personnel; the second method is that mechanical equipment takes a certain number of rock and soil samples at a certain depth in the exploration well and sends them to the ground, and then geotechnical technicians describe and record them at the wellhead based on the rock and soil samples. Although this method avoids the production safety risk of possible death, this method of using "points" instead of "surfaces" may have problems such as ① the inability to truly and accurately determine the occurrence of the strata; ② the inability to continuously and comprehensively describe the occurrence of the strata. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Combination Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention is a formation occurrence determination device in an exploration well, comprising a shell 1, an orientation sensing component 4 and an image acquisition component 5, wherein an annular track 2 is circumferentially arranged on the inner wall of the shell 1.

[0037] like Figure 2As shown, the orientation sensing component 4 includes a compass 40 located below the housing 1, and a first rotating and moving mechanism 41 connected to the compass 40. The first rotating and moving mechanism 41 is mounted on the annular track 2. The first rotating and moving mechanism 41 can move along the annular track 2, drive the compass 40 to move circumferentially along the inner wall of the exploration well, and can make the dial of the compass 40 always parallel to the inner wall of the exploration well at the corresponding position. In other words, the first rotating and moving mechanism 41 can not only drive the compass 40 to move circumferentially along the inner wall of the exploration well, but also make the dial of the compass 40 always parallel to the inner wall of the exploration well at the corresponding position during the movement of the compass 40, so as to ensure that the formation occurrence around the inner wall of the exploration well can be measured. For example, the compass 40 adopts an electronic compass.

[0038] like Figure 3 As shown, the image acquisition assembly 5 includes a camera module 50 located below the housing 1, and a second rotating and moving mechanism 51 connected to the camera module 50. The second rotating and moving mechanism 51 is assembled on the annular track 2. The second rotating and moving mechanism 51 can move along the annular track 2, drive the camera module 50 to move circumferentially along the inner wall of the exploration well, and can make the camera module 50 and the dial of the compass 40 always in a vertical state. In other words, the second rotating and moving mechanism 51 can not only drive the camera module 50 to move circumferentially along the inner wall of the exploration well, but also make the camera module 50 and the dial of the compass 40 always in a vertical state during the movement of the camera module 50, so as to ensure that the formation occurrence around the inner wall of the exploration well can be measured. The camera module 50 shoots the formation occurrence line, and the compass 40 locates each formation occurrence line shot by the camera module 50. For example, the camera module 50 is a short-focus video camera, which is a high-definition, macro camera.

[0039] Specifically, when in use, the measuring device is lowered into the exploration well, and the housing 1 is fixed to the inner wall of the exploration well; the compass 40 is made to fit the formation occurrence in the exploration well, and the first rotating and moving mechanism 41 is controlled to move along the circular track 2, driving the compass 40 to move circumferentially along the inner wall of the exploration well, and the dial of the compass 40 is always parallel to the inner wall of the exploration well at the corresponding position; at the same time, the second rotating and moving mechanism 51 is controlled to move along the circular track 2, driving the camera module 50 to move circumferentially along the inner wall of the exploration well, and the camera module 50 and the dial of the compass 40 are always in a vertical state, and the camera module 50 takes a formation occurrence map in the exploration well. Finally, each image taken by the camera module 50 is spliced ​​to form a complete, accurate, and measurable formation occurrence line of the exploration well wall.

[0040] In one embodiment, if Figure 1 As shown, the annular track 2 is an inner gear ring, and the inner gear ring is fixed on the inner wall of the housing 1. Figure 2As shown, the first rotating and moving mechanism 41 includes a first gear 410, a first connecting shaft 411, a first moving driving device and a first rotating driving device 412. The first gear 410 is meshed with the inner gear ring. In order to ensure reliable meshing of the first gear 410 with the inner gear ring and prevent meshing disengagement, a stop ring 8 is provided on the other side of the first gear 410. The first connecting shaft 411 is vertically fixed in the center hole of the first gear 410, the first moving driving device is fixedly connected to the first gear 410, and the driving end of the first moving driving device is connected to the first connecting shaft 411; the lower end of the first connecting shaft 411 extends out of the bottom of the housing 1 and is connected to the non-driving end of the first rotating driving device 412, and the driving end of the first rotating driving device 412 is fixedly connected to the compass 40.

[0041] In detail, the first connecting shaft 411 is driven to rotate by the first mobile driving device, thereby driving the first gear 410 to rotate, and then the first gear 410 is made to move circumferentially along the inner gear ring, thereby driving the compass 40 to move circumferentially along the inner wall of the exploration well. At the same time, the dial of the compass 40 is controlled by the first rotation driving device 412 to always be parallel to the inner wall of the exploration well at the corresponding position. In a specific example, the first mobile driving device and the first rotation driving device 412 are both servo motors.

[0042] Better, such as Figure 1 and Figure 3 As shown, the image acquisition component 5 also includes a directional light source 52, which is connected to the second rotating and moving mechanism 51. The second rotating and moving mechanism 51 can drive the directional light source 52 to move circumferentially along the inner wall of the exploration well, and can make the directional light source 52 and the dial of the compass 40 always in a vertical state. The directional light source 52 irradiates the shooting position of the camera module 50 to provide a sufficiently clear shooting environment. For example, the directional light source 52 is a directional light source with adjustable brightness.

[0043] Preferably, the image acquisition component 5 also includes a laser rangefinder 53, which is connected to the second rotating and moving mechanism 51. The second rotating and moving mechanism 51 can drive the laser rangefinder 53 to move circumferentially along the inner wall of the exploration well, and can make the laser rangefinder 53 and the dial of the compass 40 always in a vertical state. The laser rangefinder 53 measures the distance of each formation occurrence line photographed by the camera module 50.

[0044] In one embodiment, in combination Figure 3As shown, the second rotation and movement mechanism 51 includes a second gear 510, a second connecting shaft 511, a second moving driving device, a second rotating driving device 512 and a base 513. The camera module 50, the directional light source 52 and the laser rangefinder 53 are all fixed on the base 513, that is, the camera module 50, the directional light source 52 and the laser rangefinder 53 are integrated and installed using the base 513. The second gear 510 is meshed with the inner gear ring, the second connecting shaft 511 is vertically fixed in the center hole of the second gear 510, the second moving driving device is fixedly connected to the second gear 510, and the driving end of the second moving driving device is connected to the second connecting shaft 511. The lower end of the second connecting shaft 511 extends out of the bottom of the housing 1 and is movably connected to the base 513. Preferably, the second connecting shaft 511 is connected to the base 513 through a bearing 515, that is, the outer ring of the bearing 515 is fixedly connected to the base 513, and the inner ring of the bearing 515 is fixedly connected to the second connecting shaft 511. The lower half of the second connecting shaft 511 is provided with teeth, the second rotation driving device 512 is fixed on the base 513, and the driving end of the second rotation driving device 512 is connected to a transmission gear 514 meshing with the teeth.

[0045] Specifically, the second mobile driving device is used to drive the second connecting shaft 511 to rotate, thereby driving the second gear 510 to rotate, thereby causing the second gear 510 to move circumferentially along the inner gear ring, thereby causing the base 513 to move circumferentially along the inner wall of the exploration well, that is, driving the camera module 50, the directional light source 52, and the laser rangefinder 53 integrated on the base 513 to move circumferentially along the inner wall of the exploration well. At the same time, the second rotation driving device 512 is controlled to drive the transmission gear 514 to rotate, and the transmission gear 514 is engaged with the teeth set on the lower half of the second connecting shaft 511, thereby achieving that the camera module 50, the directional light source 52, and the laser rangefinder 53 are always in a vertical state with the dial of the compass 40.

[0046] On the basis of the above embodiments, as a more preferred embodiment, Figure 1 As shown, the measuring device also includes a shell positioning component 3, which is assembled on the shell 1. The shell 1 can be positioned on the inner wall of the exploration well by means of the shell positioning component 3. That is to say, after the shell 1 is lowered to the target depth in the exploration well, the shell 1 is fixed with the help of the shell positioning component 3, thereby ensuring that the subsequent measuring process is stable and reliable.

[0047] Preferably, Figure 1As shown, the housing positioning component 3 includes a crossbeam 30, a telescopic rod pin 31 and a telescopic drive mechanism 32. The crossbeam 30 is connected to the housing 1. Two telescopic rod pins 31 are arranged inside the crossbeam 30. A telescopic drive mechanism 32 is arranged between the two telescopic rod pins 31. The telescopic drive mechanism 32 can drive the two telescopic rod pins 31 to extend from both ends of the crossbeam 30 and pass through the housing 1 and then insert into the inner wall of the exploration well. Specifically, the crossbeam 30 is fixedly connected to the inner side of the housing 1. A hole for the telescopic rod pins 31 to enter and exit is reserved on the housing 1. When the housing 1 needs to be fixed, it is only necessary to control the telescopic drive mechanism 32 to drive the two telescopic rod pins 31 to extend from both ends of the crossbeam 30, pass through the holes reserved at the corresponding positions on the housing 1 and then insert into the inner wall of the exploration well, so that the fixing can be quickly achieved. When the fixing needs to be released, it is only necessary to control the telescopic drive mechanism 32 to drive the two telescopic rod pins 31 to retract from both ends of the crossbeam 30, so that the fixing can be quickly released.

[0048] like Figure 1 As shown, in a specific example, two cross beams 30 are installed in a cross shape on the shell 1, and telescopic rod needles 31 and telescopic driving mechanisms 32 are provided in the two cross beams 30, which can make the positioning of the shell 1 more firm and reliable.

[0049] For example, the specific structure of the telescopic driving mechanism 32 is: it includes a motor, a gear at the driving end of the motor and a rack meshing with the gear. The telescopic rod needle 31 is connected to the rack. By controlling the direction of the gear controlled by the motor, the reciprocating motion of the rack is realized, thereby realizing the telescopic movement of the telescopic rod needle 31.

[0050] For example, the housing positioning component 3 may also be a flexible support wheel that can be used to fix the entire device in the exploration well.

[0051] Combination Figure 1 and Figure 4 As shown, preferably, a traction rope 6 is connected to the crossbeam 30, and the traction rope 6 is used to lift and lower the measuring device, which is convenient for operation and control. For example, the traction rope 6 is a high-resistance traction rope.

[0052] Based on the above embodiment, as a more preferred embodiment, Figure 4As shown, the measuring device further includes an execution control and data storage handbook 7, which is electrically connected to the first rotating and moving mechanism 41, the camera module 50 and the second rotating and moving mechanism 51. The control and data storage handbook 7 is used to control the operation of each actuator in the measuring device, and store data collected by the camera module 50 and the laser rangefinder 53. Specifically, the execution control and data storage handbook 7 is electrically connected to the telescopic drive mechanism 32, the first mobile drive device, the first rotating drive device 412, the second mobile drive device, the second rotating drive device 512, the camera module 50, the directional light source 52, and the laser rangefinder 53 through a cable 9, and the cable 9 is integrally installed on the traction rope 6 and moves downward with the traction rope 6.

[0053] A method for using a formation occurrence determination device in an exploration well according to an embodiment of the present invention includes:

[0054] Lower the measuring device into the exploration well and fix the housing 1 to the inner wall of the exploration well;

[0055] The compass 40 is made to fit the formation occurrence in the exploration well, and the first rotating and moving mechanism 41 is controlled to move along the circular track 2, so as to drive the compass 40 to move circumferentially along the inner wall of the exploration well, and the dial of the compass 40 is always parallel to the inner wall of the exploration well at the corresponding position; at the same time, the second rotating and moving mechanism 51 is controlled to move along the circular track 2, so as to drive the camera module 50 to move circumferentially along the inner wall of the exploration well, and the camera module 50 and the dial of the compass 40 are always in a vertical state, and the camera module 50 takes a picture of the formation occurrence in the exploration well.

[0056] In one embodiment, when it is necessary to measure the formation occurrence in the exploration well, the first rotating movement mechanism 41 and the second rotating movement mechanism 51 corresponding to the orientation sensing component 4 and the image acquisition component 5 are first connected to the annular track 2 on the housing 1. Specifically, the first gear 410 and the second gear 510 are meshed with the inner gear ring. Then, the whole device is hoisted into the location where the formation occurrence needs to be measured in the exploration well by the traction rope 6. The telescopic drive mechanism 32 set in the crossbeam 30 is controlled by the execution control and data storage handbook 7 to make the telescopic rod needle 31 extend out of the device. The protective shell 1 is inserted into the wall of the exploration well so that the device is fixed in the exploration well as a whole. Then, the compass 40 is made to fit the formation occurrence in the exploration well through the cooperation of the first mobile drive device and the first rotation drive device 412. At the same time, the camera module 50, the directional light source 52 and the laser rangefinder 53 are simultaneously aimed at the compass 40 and the formation occurrence line measured by it through the cooperation of the second mobile drive device and the second rotation drive device 512. Then, the formation occurrence line is measured and recorded along the well wall for one week, and finally the formation occurrence parameters are derived from the intersection shape of the formation occurrence line and the well wall.
