Description

Technical Field

[0001] The present invention relates to the fields of geological prospecting, geophysical prospecting engineering, space drilling, and in particular to an integrated drilling tool for drilling, sampling, and real-time measurement. Background Art

[0002] Necessity of drilling, sampling, and real-time measurement and engineering demand background:

[0003] In order to find out the underground rock and soil properties, structural structure, spatial distribution and other contents of the survey work, the drilling equipment and devices are used to directly enter the underground space. During the drilling process, the engineering properties of the rock and soil, stratigraphic characteristics and geological structure information are obtained by taking rock and soil samples and measuring the cross section of the hole wall. By studying the lithological characteristics, thickness and lateral changes of each stratum, information and data are provided to determine the structure and properties of each layer of rock and soil in the natural state, clarify the occurrence and weathering zone of the rock stratum, the location, width and nature of the fault fracture zone, and understand the development degree and depth changes of joints and fissures.

[0004] In order to accurately identify the physical and mechanical properties of rock and soil, the natural structure of rock and soil must be maintained during the drilling process to obtain low-disturbance samples, providing technical indicators for quantitative evaluation of geotechnical engineering problems. Through the analysis of formation rock samples by technicians, parameters such as formation permeability, porosity and other rock properties can be analyzed to obtain direct information on the formation, which serves as a basis for geological analysis.

[0005] Current status and problems of drilling, sampling and real-time measurement:

[0006] Different problems will be encountered when drilling into different formations, which puts high demands on the acquisition of low-disturbance samples. In order to clarify the characteristics of the formation, the best method is full-hole sampling, and the goal of characterizing the distribution characteristics of the formation can be achieved through full-hole core sampling. However, full-hole sampling is costly and difficult, and complex formations can easily lead to sampling failures. Especially for special and harsh environments such as space drilling, unmanned sampling is extremely difficult, and full-hole unmanned sampling is difficult to achieve. Therefore, the need for integrated drilling, sampling, and measurement is very urgent.

[0007] At present, there is no integrated technology and method for drilling, sampling and measuring. The main technology used in engineering is to design drilling and sampling as a combined drilling tool structure, and to achieve sampling while drilling. The specific process is to use the drill bit to drill the sampling hole while the sampling tool completes the sampling work, then the drill is pulled out to complete the sampling, and then the sample is tested, tested and analyzed to obtain the required data and the occurrence and weathering zone of some rock formations, the degree of development of joints and fissures and other formation-related information. It can be seen that the measurement must be completed after drilling, and the drilling tool in the hole must also be extracted. The samples obtained by sampling can only be taken to the ground for analysis. This drilling, sampling and measuring method has a long cycle, high cost, low accuracy, and cannot achieve real-time data acquisition. The information on depth changes and the physical and mechanical properties of rock and soil is not complete and accurate. Summary of the invention

DETAILED DESCRIPTION

[0047] Combine the following Figure 1-14 The present invention is further described in detail with reference to the following examples. The following examples are merely illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0048] An integrated drilling tool for drilling, sampling and real-time measurement, comprising a sampling tube 3 and a drill rod 2 coaxially sleeved outside the sampling tube 3, a drill bit 1 being arranged at the end of the drill rod 2, and a measuring component being arranged on the peripheral surface of the drill rod 2 near the drill bit 1;

[0049] The measuring member comprises a horizontally arranged fixed positioning seat 6, a stepped hole 27 is opened along the axis of the fixed positioning seat 6, and the stepped surface of the stepped hole 27 faces the drill pipe 2; a measuring sliding shaft 7 is passed through the fixed positioning seat 6, a measuring sensor 8 is installed at one end of the measuring sliding shaft 7 away from the drill pipe 2, and the other end of the measuring sliding shaft 7 passes through the side wall of the drill pipe 2 and extends into the annulus between the drill pipe 2 and the sampling tube 3;

[0050] The end of the measuring sliding shaft 7 away from the drill rod 2 extends outward to form a flange 9, and the end of the fixed positioning seat 6 away from the drill rod 2 is provided with an opening for the flange 9 to enter and exit the fixed positioning seat 6; a spring positioning seat 10 is arranged in the large circular hole of the step hole 27, and the spring positioning seat 10 is threadedly matched with the inner wall of the large circular hole of the step hole 27, and a spring 11 is sleeved on the measuring sliding shaft 7, and the two ends of the spring 11 are respectively supported between the spring positioning seat 10 and the flange 9, and the preload force of the spring 11 is adjusted by adjusting the spring positioning seat 10;

[0051] An end cover positioning plate 12 is formed at one end of the measuring sliding shaft 7 located in the annulus at the spring 11 fixing seat, and a locking piece is arranged between the end cover positioning plate 12 and the inner wall of the drill pipe 2, so that the end cover positioning plate 12 is restricted in the annulus between the drill pipe 2 and the sampling tube 3 by the locking piece.

[0052] The locking member includes a push rod 13 and two swing rods 14. A vertical slide groove 15 is opened above the end cover positioning plate 12 corresponding to the inner wall of the drill rod 2. The center of the end cover positioning plate 12 is located on the midline of the slide groove 15. A sliding pin 16 is arranged in the slide groove 15. The swing rod 14 is a bent rod. A fulcrum shaft 17 is arranged below the high point of the slide groove 15 on both sides. The two swing rods 14 are symmetrically arranged. The corners of the swing rods 14 are sleeved on the fulcrum shaft 17. The ends of the two swing rods 14 above the corners are cross-arranged below the sliding pin 16. The push rod 13 extends from the end of the drill rod 2 away from the drill bit 1 to the space between the drill rod 2 and the sampling tube 3. The two swing arms 14 are connected to the annulus between the two ends of the drill pipe 2 and the sliding pin 16; when the sliding pin 16 is located at the high point of the slide groove 15, a section below the corner of the two swing arms 14 is stuck between the end cover positioning plate 12 and the inner wall of the drill pipe 2; when the sliding pin 16 moves from the high point to the low point, the sliding pin 16 presses down the two swing arms 14 and moves at the same time, and one end below the corner of the two swing arms 14 rotates around the fulcrum axis 17 and moves when the sliding pin 16 moves to the low point of the slide groove 15 or swings to the outside of the coverage area of ​​the end cover positioning plate 12 during the movement, and the measuring sliding shaft 7 moves toward the outside of the drill pipe 2 under the elastic force of the spring 11, and brings the end cover positioning plate 12 into the large circular hole of the step hole 27.

[0053] At least three groups of spring pressing plates 26 are evenly distributed on the circumferential surface of the flange 9. The spring pressing plates 26 are contracted in the annular gap between the flange 9 and the opening for the flange 9 to enter and exit. The fixed end of the spring pressing plate 26 is located at a position of the flange 9 close to the end face of the opening, and the pop-up end abuts against the inner wall of the opening away from the flange 9 close to the end face of the opening.

[0054] The upper surface of the end cover positioning plate 12 and the swing rod 14 is processed into a slope 19 along the swing sector of the swing rod 14, and the side of the slope 19 close to the end cover positioning plate 12 is the lower end. The section of the swing rod 14 in contact with the end cover positioning plate 12 is covered with a rolling sleeve 20.

[0055] The inclined surface 19 facilitates the positioning of the rolling sleeve 20 in the retracted state and limits the continued rotation toward the center of the circle; when the sensor 8 needs to be extended, the rolling sleeve 20 only needs to overcome the resistance of the inclined surface 19 and roll outward to achieve the removal of the rolling sleeve 20 and the horizontal movement of the positioning plate.

[0056] The highest and lowest points of the end cover positioning plate 12 are both provided with positioning blocks 21, and corresponding positioning grooves 22 are opened in the large circular holes of the step holes 27. The positioning grooves 22 restrict the end cover positioning plate 12 to move outwardly along the axial straight line but not to swing or rotate.

[0057] Corresponding to the distribution of the spring pressing piece 26, a guide slot 23 is provided on the inner wall of the opening for the flange 9 to enter and exit. When the measuring sliding shaft 7 slides relative to the fixed positioning seat 6, the spring pressing piece 26 moves synchronously in the guide slot 23. The guide slot 23 allows the spring pressing piece 26 to slide outward only along the straight line of the guide slot 23, while limiting the circumferential movement of the spring pressing piece 26.

[0058] The drill bit 1 includes a truncated cone-shaped base body, a hollow cone is formed in the base body, and grooves are formed on the conical surface of the base body to facilitate the discharge of rock cuttings at the bottom of the hole; a plurality of cutting tools 5 are evenly distributed on the base body, and the cutting tools 5 are firmly welded to the drill bit 1 body, and the lower end of the cutting tool 5 protrudes from the bottom surface of the drill bit 1 by 2 to 3 mm to ensure that the cutting tool 5 can smoothly cut into the rock, and the outer edge of the cutting tool 5 protrudes from the outermost edge of the base body, so that there is a gap between the drill bit 1 body and the hole wall to ensure smooth powder discharge; the outer spiral groove 4 is arranged on the part connected to the drill rod 2 above the base body, which is mainly used to discharge rock cuttings in the hole.

[0059] The positioning groove 22 is filled with a gasket 24, and the depth of the positioning block 21 entering the positioning groove 22 is adjusted by the gasket 24. When the measured pressure needs to be adjusted, the adjustment gasket 24 can be placed in the step at the right end of the fixed positioning seat 6 to adjust the pressure through displacement;

[0060] When different measurements are required, the measurement sensor 8 can be replaced to achieve the collection and transmission of data, images, etc.

[0061] A sliding bearing 25 is installed on the upper end surface of the hollow cone, and the sampling tube 3 is arranged inside the drill rod 2 through the sliding bearing 25. The sampling tube 3 remains stationary to achieve the requirements of low disturbance or in-situ sampling of rock and soil samples. When the drill bit 1 rotates, the sampling tube 3 and the drill bit 1 are isolated from each other by the sliding bearing 25 in the middle. At the same time, the sliding bearing 25 can also ensure that the axial position of the sampling tube 3 remains in a straight position. The sampled sample enters the sampling tube 3 along the conical surface of the inner surface of the drill bit 1, which is conducive to sampling.

[0062] Real-time measurement principle:

[0063] When drilling, the measuring sensor 8 is retracted into the fixed positioning seat 6 through the measuring sliding shaft 7 and the end cover positioning plate 12, and the fixed positioning seat 6 is tightly connected to the drill pipe 2; the spring 11 is locked in the fixed positioning seat 6 through a threaded connection on the fixed seat, and the spring 11 is in a compressed state; the four spring pressing plates 26 are also retracted in the groove at the left end of the fixed positioning seat 6; at this time, the sliding pin 16 is at the upper end of the slide groove 15, and the rocker arm 14 is located at the lowest end of the inclined surface 19 of the end cover positioning plate 12, fixing the end cover positioning plate 12 (cannot move horizontally or rotate).

[0064] When drilling is completed and reaches the designated position, if in-hole measurement or image transmission is required, the push rod 13 is pressed downward, and the push rod 13 acts on the sliding pin 16, and the sliding pin 16 moves vertically downward along the groove, and the swing rod 14 rotates outward around the fulcrum axis 17, and the rolling sleeve 20 on the swing rod 14 rolls outward along the inclined surface 19 on the end cover positioning plate 12 to the outside of the end cover positioning plate 12. At this time, the end cover positioning plate 12 enters the large circular hole of the step hole 27 under the action of the spring 11, and the measuring sliding shaft 7 also moves away from the drill pipe 2, and then pushes the measuring sensor 8 to the outside of the fixed positioning seat 6. At this time, the four spring pressing pieces 26 installed in the guide slide groove 23 pop out and support the end surface of the fixed positioning seat 6, completing the positioning of the measuring sensor 8. The probes of the sensors on both sides extending from the fixed positioning seat 6 touch the hole wall, and the pressure, friction, temperature, displacement and other parameters are measured online in real time through the scratches on the rock wall, providing accurate data for evaluating the physical and mechanical parameters of the hole wall. The probe of the measuring sensor 8 can be replaced by a camera to perform real-time image transmission.

[0065] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
