Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of oil and gas development, and in particular, to a core climbing parameter testing device and a testing method. Background Art
[0002] This section aims to provide background or context for the embodiments of the present invention described in the claims. The description herein is not admitted to be prior art merely by including it in this section.
[0003] Core is a precious and non-renewable resource in the research work of oil and gas exploration and development, and is also one of the most crucial and intuitive physical materials. Most of the oil and gas geological analysis data and geophysical exploration parameters come from the core. In the oil and gas development in a wide range of engineering fields such as drilling, fracturing stimulation, and sand control, the understanding of rock structures is very important.
[0004] The parameters expected to be obtained from the core include mineral composition, microstructure, porosity, permeability, saturation, rock electrical parameters, geomechanical parameters, etc. The methods for obtaining these parameters are divided into destructive and non-destructive types, with the destructive type being the main one. For example, the analysis methods for mineral composition include X-ray diffraction analysis, chemical analysis, rock thin section, CT method, etc.; the analysis methods for microstructure include electron microscopy method, CT method; the analysis methods for porosity include image method, mercury injection method, nuclear magnetic resonance method, helium method, acoustic method, etc.; the analysis methods for permeability include Darcy method, digital core method, pressure pulse method, etc.
[0005] These analysis methods and devices are often designed for a specific parameter, without fully considering the full exploitation of the value of the core sample itself, and a large number of destructive sampling methods are used to prepare so-called standard samples to obtain limited single and single-point parameters. Through research, it is found that all the information expected to be obtained from the core can be characterized by one or more combinations of sound, light, electricity, and magnetism, which provides a theoretical basis for establishing a non-destructive, full-volume, and full-parameter core parameter extraction device and method. More precisely, this device should be called a full-parameter scanning device, and the most suitable test principles for this concept are advanced microscopic visualization experimental means such as CT and nuclear magnetic resonance. However, such experimental devices have problems such as being very expensive, accompanied by radiation during the test process, and extremely high test costs, and cannot be used as a general method in production practice. In view of the above existing problems, multi-parameter joint measurement and volume scanning are pursued in terms of device function, non-destructive and non-radiative are selected in terms of test principle, and intelligent control is realized in terms of control method.

[0037] Embodiment 1
[0038] As Figure 1 , Figure 2 and Figure 3As shown in the figure, the present invention provides a core climbing parameter testing device, including: a core installation mechanism 1, which has two core clamping structures 11 and two end face detection structures 12. The two core clamping structures 11 are used to clamp and fix the core 3 from the axial two ends of the core 3, and the two end face detection structures 12 are installed on the two core clamping structures 11; a climbing parameter mechanism 2, including a walking structure 21, a positioning structure 22 and a side face detection structure 23. The climbing parameter mechanism 2 is movably arranged on the core 3 through the walking structure 21; a control mechanism, which is electrically connected to the walking structure 21 and the positioning structure 22 respectively. The positioning structure 22 is used to obtain the climbing parameter position information of the climbing parameter mechanism 2 relative to the core 3 and output it to the control mechanism, and the control mechanism is used to control the walking structure 21 to move according to a preset climbing parameter program; a data analysis mechanism, which is electrically connected to the side face detection structure 23, the end face detection structure 12 and the control mechanism respectively. The end face detection structure 12 is used to detect the core 3 from the end of the core 3 to obtain the end core parameter information and transmit it to the data analysis mechanism. The side face detection structure 23 is used to detect the core 3 from the side of the core 3 to obtain the side core parameter information and transmit it to the data analysis mechanism. The control mechanism can transmit the climbing parameter position control information to the data analysis mechanism, and the data analysis mechanism can generate the core parameter distribution information of the core 3 according to the side core parameter information, the end core parameter information and the climbing parameter position information.
[0039] For the core climbing parameter testing device and testing method of the present invention, by setting two core clamping structures 11 to clamp and fix the core 3 from the axial two ends of the core 3, and arranging two end face detection structures 12 on the two core clamping structures 11, the two end face detection structures 12 can detect the core 3 from the two ends of the core 3, so as to obtain the end core parameter information; furthermore, by arranging a climbing parameter mechanism 2 around the core 3, the climbing parameter mechanism 2 can move around the core 3 through the walking structure 21, so that the side face detection structure 23 can detect the core 3 from all directions around the core 3 without dead angle of 360°, so as to obtain the side core parameter information (including but not limited to core parameters such as the crack width, length, area, pore porosity, crack porosity, hole size and hole connection state inside the core 3 obtained by quantitative scanning calculation); and by obtaining the climbing parameter position information through the positioning structure 22, the detection position information of the side face detection structure 23 can be analyzed, so that the core parameter distribution information can be generated according to the end core parameter information, the side core parameter information and the climbing parameter position information, and further the void structure and distribution characteristics inside the real rock mass can be seen more clearly, providing a reliable basis for further experimental research and analysis.
[0040] Specifically, in combination with Figure 3 、 Figure 4 and Figure 5As shown, the shape of the core 3 is preferably generally cylindrical, so that the traveling structure 21 can not only rotate circumferentially S around the core 3, but also move axially Z along the core 3, and through cooperation, the sea cucumber climbing mechanism 2 can have multiple sea cucumber climbing paths. Between the data analysis mechanism and the side detection structure 23, the end face detection structure 12, and the positioning structure 22, and between the control mechanism and the traveling structure 21, it can be a wireless communication connection or a wired communication connection through a signal line. The control mechanism can be a control cabinet integrated with a controller, the data analysis mechanism can be integrated in a computer, and the control mechanism can also be communicatively connected to the data analysis mechanism. In addition to functions such as controlling the traveling of the traveling structure 21 and setting the sea cucumber climbing program, the control mechanism can also generate sea cucumber climbing control information for controlling the traveling of the traveling structure 21 and transmit the sea cucumber climbing control information to the data analysis mechanism. In addition to processing and analyzing the side core parameter information, the end core parameter information, and the sea cucumber climbing position information to generate core parameter distribution information, the data analysis mechanism can also monitor the working state of the control mechanism according to the sea cucumber climbing control information and realize the storage of various data.
[0041] Combined Figure 2 and Figure 3 As shown, the sea cucumber climbing mechanism 2 further includes a cylinder body 24, the cylinder body 24 is sleeved outside the core 3, and the traveling structure 21, the side detection structure 23, and the positioning structure 22 are all installed inside the cylinder body 24. By providing the cylinder body 24, it can not only protect the internal traveling structure 21, side detection structure 23, and positioning structure 22, but also provide a better detection environment for the side detection structure 23. The traveling structure 21, the side detection structure 23, and the positioning structure 22 are installed on the inner wall surface of the cylinder body 24. The shape of the cylinder body 24 is preferably generally a hollow cylinder body 24 with both ends open, so that the cylinder body 24 can rotate at any angle with the traveling structure 21, and the detection distance between the side detection structure 23 and the core 3 remains unchanged. Specifically, a communication structure 25 is also installed on the cylinder body 24, and the communication structure 25 is communicatively connected to the control mechanism and the data analysis mechanism respectively. A cylindrical frame 241 is embedded on the cylinder body 24 to improve its structural strength.
[0042] As Figure 2 and Figure 3As shown in the figure, in the embodiments of the present invention, the traveling structure 21 includes a plurality of traveling components 211, and the plurality of traveling components 211 are arranged along the circumferential direction and the axial direction of the cylinder 24. The plurality of traveling components 211 arranged circumferentially can drive the cylinder 24 to rotate circumferentially around the core 3 through traveling cooperation, and the plurality of traveling components 211 arranged axially can drive the cylinder 24 to move axially along the core 3 through traveling cooperation. Further, through the cooperation of circumferential rotation and axial movement, different core climbing modes of the core climbing mechanism 2 can be realized, such as spiral core climbing, planar core climbing, axially reciprocating rotary core climbing (that is, translating a certain distance axially after rotating one circle circumferentially, and so on alternately), array core climbing, etc.
[0043] Specifically, the traveling component 211 includes a micro motor, a traveling actuator, and a power supply structure. The micro motor is communicatively connected to the control mechanism, the traveling actuator is in contact with the side surface of the core 3 and is connected to the micro motor; the power supply structure is electrically connected to the micro motor, and the power supply structure includes a power battery or electrically connects the micro motor to an external power supply through a cable. Among them, the control mechanism can be a microprocessor or other electronic circuits, which is used to receive input signals and generate control signals according to the required speed and torque of the micro motor. The control signal can be an analog or digital signal sent to a variable power supply, which delivers current to the micro motor, thereby driving the micro motor to rotate. The traveling actuator can be connected to the bearing of the micro motor, so that the traveling actuator rotates under the drive of the micro motor, and the control mechanism can also adjust the rotation speed of the micro motor to adjust the moving speed of the traveling actuator. The traveling actuator can be a universal wheel.
[0044] As Figure 2 and Figure 3 As shown in the figure, in the embodiments of the present invention, the side detection structure 23 includes a plurality of side detection components 231, and the plurality of side detection components 231 are arranged along the circumferential direction and the axial direction of the cylinder 24 on the inner wall surface of the cylinder 24. Specifically, the plurality of side detection components 231 can be the same core detection structure in the prior art, or a combination of multiple core detection structures in the prior art. In some embodiments of the present invention, the plurality of side detection components 231 are all one of an ultrasonic probe, a high-definition micro camera, and a rock electricity sensor. In other embodiments of the present invention, the plurality of side detection components 231 are a combination of at least two of at least one ultrasonic probe, at least one high-definition micro camera, and at least one rock electricity sensor. The more the side detection components are arranged circumferentially, the finer the test; the more the side detection components are arranged axially, the higher the test efficiency.
[0045] As Figure 2 and Figure 3As shown, in the embodiment of the present invention, the positioning structure 22 includes at least one linear displacement sensor 221 and at least one angular displacement sensor 222. Among them, the distance of its axial movement along the core 3 can be measured by the linear displacement sensor 221, that is, the distance of the climbing mechanism 2 moving along the axial direction of the core 3; the angle of its circumferential rotation around the core 3 can be measured by the angular displacement sensor 222, that is, the angle of the climbing mechanism 2 rotating circumferentially around the core 3; therefore, according to the distance of the climbing mechanism 2 moving along the axial direction of the core 3 and the angle of its circumferential rotation around the core 3, the climbing position information of the climbing mechanism 2 relative to the core 3 can be analyzed and generated.
[0046] Among them, the number of the side detection members 231 in the inner side detection structure 23 of the cylinder 24, the number of the traveling components 211 in the traveling structure 21, and the specific number of the linear displacement sensor 221 and the angular displacement sensor 222 in the positioning structure 22 may not be specifically limited, and they are reasonably distributed inside the cylinder 24 to ensure the balance of the entire climbing mechanism 2 during climbing. However, the more the number, the more complex the design and the higher the cost.
[0047] As Figure 1 shown, in the embodiment of the present invention, detection holes are provided in both core clamping structures 11, and the end face detection structure 12 passes through the detection holes of the two core clamping structures 11. In this embodiment, the core clamping structure 11 is generally an inflatable rubber sleeve structure, and by controlling the inflation and deflation of the rubber sleeve structure, the clamping and releasing of the end of the core 3 are realized.
[0048] Specifically, the core mounting mechanism 1 further includes a base 13, a top cover 14, and a plurality of support columns 15. The bottom ends of the support columns 15 are fixed on the base 13, the top cover 14 is detachably mounted on the plurality of support columns 15, one core clamping structure 11 is mounted on the base 13, and the other core clamping structure 11 is mounted on the top cover 14. The top cover 14 can adjust its mounting height on the plurality of support columns 15 according to the axial length of the core 3. Through holes matching the detection holes on the core clamping structure 11 are provided on both the base 13 and the top cover 14, so that the detection ends of the end face detection structure 12 pass through the two detection holes to contact the two ends of the core 3, and the communication ends of the end face detection structure 12 pass out from the two through holes to facilitate communication connection with the data analysis mechanism. The top cover 14 is slidably matched with the plurality of support columns 15 along the axial direction of the core 3.
[0049] Embodiment 2
[0050] The present invention also provides a core climbing parameter testing method, which uses a core climbing parameter testing device. In this embodiment, the specific structure, working principle, and beneficial effects of the core climbing parameter testing device are the same as those of the core climbing parameter testing device in Embodiment 1, and will not be elaborated here.
[0051] Combined withFigure 1 and Figure 2 As shown in Figure 1 and Figure 2 , the core climbing parameter testing method of the present invention includes the following steps: Select the first type of core parameters; according to the first type of core parameters, select the corresponding side detection structure 23 and end face detection structure 12 and install them on the core climbing parameter testing device; according to the first type of core parameters, set the climbing parameter program in which the walking structure 21 in the climbing parameter mechanism 2 drives the side detection structure 23 to walk; wherein, the climbing parameter program includes a climbing parameter path, a climbing parameter mode and / or a climbing parameter point position; clamp and fix the core 3 between the two core clamping structures 11; start the walking structure 21, and the side detection structure 23 walks according to the climbing parameter program driven by the walking structure 21 to obtain the side core parameter information, the end face detection structure 12 obtains the end core parameter information, and obtains the climbing parameter position information of the climbing parameter mechanism 2 relative to the core 3 through the positioning structure 22; generate the distribution information of the first type of core parameters of the core 3 according to the side core parameter information, the end core parameter information and the climbing parameter position information; generate the distribution information of various types of core parameters in the same way as above.
[0052] Specifically, the installation of the core 3 includes: First, place the core 3 on the core clamping structure 11 connected and fixed to the bottom plate, and after the lower end of the core 3 is in close contact with the end face detection structure 12 on the core clamping structure 11, clamp the lower end of the core 3 through the core clamping structure 11; then, sleeved the climbing parameter mechanism 2 from the upper end of the core 3 outside the core 3 and slowly place it at the lower end of the core 3 from top to bottom; then, the climbing parameter mechanism 2 can be rotated one circle to check whether the walking execution parts of each side detection part 231 and each walking component 211 are in good contact with the cylindrical surface of the core 3; slide and lift the top cover 14 on the plurality of support columns 15, adjust the height of the top cover 14 according to the axial length of the core 3 until the upper end of the core 3 is in contact with the end face detection structure 12 on the core clamping structure 11 connected and fixed to the top cover 14, and then fix the top cover 14 on the plurality of support columns 15 through pins or other connecting parts, and finally clamp the upper end of the core 3 through the core clamping structure 11 on the top cover 14, so as to complete the installation of the core 3 on the core climbing parameter testing device.
[0053] In addition, before testing the core 3, the core 3 can be processed to ensure that the end faces at both ends of the core 3 are perpendicular to its axis and the surface is smooth. The cylindrical surface (i.e., the side surface) of the core 3 is rotated and polished smoothly with sandpaper, and then the surface of the core 3 is cleaned with an appropriate cleaning agent, and finally dried. After the test is completed, the core 3 is removed from the core installation mechanism 1, and then each side detection part 231 of the climbing parameter mechanism 2 is removed from the cylinder body 24 for storage.
[0054] Combined with Figure 6 and Figure 7As shown, in an embodiment of the present invention, the multiple side detection members 231 of the side detection structure 23 are multiple high-definition micro cameras. The core climbing method is to alternately rotate circumferentially around the core 3 and move axially along the core 3 (that is, rotate one circle circumferentially and then translate a certain distance axially, and so on alternately). The side core parameter information is the local image of the core. The core climbing test method includes generating a scanning image of the entire core based on the side core parameter information and the climbing position information. Among them, the high-definition micro cameras are wirelessly communicatively connected to the data analysis mechanism.

The core climbing method is to rotate circumferentially around the core 3. The side core parameter information is the core wave velocity. The core climbing test method includes generating an anisotropy analysis diagram of the core wave velocity based on the side core parameter information and the climbing position information. Among them, the ultrasonic probes are wired communicatively connected to the data analysis mechanism through signal cables.
