Description

Technical Field

[0001] This utility model belongs to the technical field of petroleum sampling devices, and relates to a multi-level sampling device for petroleum exploration. Background Technology

[0002] Petroleum is a viscous, dark brown liquid, often referred to as the "blood of industry," and is found in certain areas of the Earth's upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. It is one of the primary energy sources and a major target for geological exploration; therefore, sampling and analysis of petroleum are necessary before extraction. Currently, many oil extraction sampling devices have appeared on the market. However, these sampling devices can only sample a single layer of oil and cannot sample every layer of oil. To obtain samples from multiple oil layers, multiple sampling processes must be performed, resulting in poor sampling quality and wasted resources.

[0003] Therefore, in view of the problem that the existing oil sampling devices can only sample oil from a single layer and cannot sample each layer of oil, and that to obtain samples from multiple oil layers, multiple samplings must be performed repeatedly, resulting in poor sampling results and wasted resources, this application provides a multi-layer sampling device for oil exploration. The device uses a drill bit to enter different locations underground, and then the feed pipe inside the drill bit pours the oil extracted from different locations into the storage seats in different areas of the rotating disk, which facilitates sampling of each layer of oil and prevents oil from different layers from mixing and affecting the oil sampling results. Utility Model Content

[0004] The purpose of this invention is to provide a multi-level sampling device for oil exploration, which solves the problem of difficulty in multi-level oil sampling in the existing technology.

[0005] The technical solution adopted in this utility model is a multi-level sampling device for petroleum exploration, including a sampling tank. A cover plate is fixedly connected to the opening of the sampling tank. A driving component is fixedly connected to the bottom of the inner wall of the sampling tank. A rotating disk is fixedly connected to the top of the driving component. Several storage components are arranged on the upper surface of the rotating disk, and the storage components are symmetrical about the center of the rotating disk. A lifting component is fixedly connected to one side of the sampling tank. A sampling component is arranged on one side of the lifting component. A sampling tube is fixedly connected to the sampling component. The sampling tube extends into the interior of the sampling tank, and the outlet position of the sampling tube corresponds to the position of the storage component.

[0006] The features of this utility model also include: The drive assembly includes a servo motor fixedly connected to the bottom of the inner wall of the sampling tank, a first rotating gear fixedly connected to the center of the rotating disk near the bottom of the inner wall of the sampling tank, and a second rotating gear fixedly connected to the output end of the servo motor. The second rotating gear meshes with the first rotating gear.

[0007] The storage assembly includes a storage seat fixedly connected to the upper surface of a rotating disk. A step is provided on the upper side wall of the storage seat. An ejector block is fixedly connected at the corner of the step. The cross-section of the ejector block is a right triangle, with the two right-angled sides corresponding to the two sides of the step. A cylinder is fixedly connected to the inner wall of the rotating disk corresponding to the ejector block. The output end of the cylinder faces the ejector block and a pusher block is fixedly connected to the output end of the cylinder. The pusher block and the inclined surface of the ejector block cooperate with each other.

[0008] The lifting assembly includes a track frame fixedly connected to one side of the sampling tank, a lead screw fixedly connected inside the track frame, a lifting motor fixedly connected to the bottom end of the track frame, the output end of the lifting motor fixedly connected to one end of the lead screw, and the lead screw threadedly connected to the sampling assembly.

[0009] The sampling assembly includes a connecting plate fixedly connected to the lifting assembly. A sampling head is fixedly connected to the bottom surface of the connecting plate, and a pump is fixedly connected to the upper surface of the connecting plate. The input end of the pump is connected to the sampling head, and the output end of the pump is connected to the sampling tube.

[0010] A receiving platform is fixedly connected between two adjacent storage components on the rotating disk. The receiving platform is a sloping structure with a high middle and low ends, and each end of the receiving platform corresponds to a storage component.

[0011] Each receiving platform has a connecting rod fixedly connected to the side corresponding to the rotating disk. The connecting rod extends into the rotating disk and is fixedly connected to a driven gear. Each driven gear corresponding to the connecting rod meshes with a main gear, and the main gear is fixedly connected to a rotary motor.

[0012] The bottom of the sampling container is fixedly connected to rollers, which are symmetrically arranged at the bottom of the sampling container.

[0013] The beneficial effects of this utility model are: 1. The petroleum sampling device provided in this application changes the position of the sampling component through the lifting component to collect petroleum samples at different depths. At the same time, the rotating disk switches the storage component corresponding to the sampling tube, and different storage components are used to store different petroleum samples. This allows the device to collect multiple layers of petroleum samples after a single setup, thereby improving the sample collection efficiency.

[0014] 2. The petroleum sampling device provided in this application allows the petroleum collected by the sampling component to be directly poured into a storage seat in a specific area on a rotating disk through a sampling tube. The rotation of the rotating disk ensures independent storage of each sample layer, improving the reliability of the analytical data. Simultaneously, after sampling, the storage seat is automatically ejected from the rotating disk through the cooperation of the ejector block, cylinder, and pusher block, facilitating quick and safe sample removal by operators, improving operational efficiency, and reducing the difficulty and risk of manual operation.

[0019] The device provided in this application, during use, extracts sample oil through the sampling component 7, and then transports the oil through the sampling tube 8 to the storage component 5 on the rotating disk 4. After one storage component 5 has been collected, the drive component 3 drives the rotating disk 4 to rotate, transporting another storage component 5 below the sampling tube 8. Simultaneously, the lifting component 6 moves the sampling component 7 to another oil reservoir, delivering the oil from the new reservoir to the new storage component 5. Through the switching of the storage components 5 and the movement of the sampling components, oil samples from different layers can be collected.

[0020] Example 2: like Figure 1 and Figure 2 As shown, the sample tank includes a sampling container 1, a cover plate 2 fixedly connected to the opening of the sampling container 1, a drive assembly 3 fixedly connected to the bottom of the inner wall of the sampling container 1, a rotating disk 4 fixedly connected to the top of the drive assembly 3, a plurality of storage components 5 arranged on the upper surface of the rotating disk 4, and the storage components 5 are symmetrical about the center of the rotating disk 4. A lifting assembly 6 is fixedly connected to one side of the sampling container 1, a sampling assembly 7 is arranged on one side of the lifting assembly 6, a sampling tube 8 is fixedly connected to the sampling assembly 7, the sampling tube 8 extends into the interior of the sampling container 1, and its outlet position corresponds to the position of the storage components 5.

[0021] like Figure 3 As shown, the drive assembly 3 includes a servo motor 9 fixedly connected to the bottom of the inner wall of the sampling tank 1, a first rotating gear 10 fixedly connected to the center of the rotating disk 4 near the bottom of the inner wall of the sampling tank 1, and a second rotating gear 11 fixedly connected to the output end of the servo motor 9. The second rotating gear 11 and the first rotating gear 10 mesh with each other.

[0022] In order to meet the switching requirements of the storage component 5, the rotating disk 4 needs to be driven by the drive component 3. Therefore, in this application, the power is provided by the servo motor 9, and the power is transmitted by the first rotating gear 10 and the second rotating gear 11 to drive the rotating disk 4 to rotate.

[0023] Example 3: like Figure 1 and Figure 2 As shown, the sample tank includes a sampling container 1, a cover plate 2 fixedly connected to the opening of the sampling container 1, a drive assembly 3 fixedly connected to the bottom of the inner wall of the sampling container 1, a rotating disk 4 fixedly connected to the top of the drive assembly 3, a plurality of storage components 5 arranged on the upper surface of the rotating disk 4, and the storage components 5 are symmetrical about the center of the rotating disk 4. A lifting assembly 6 is fixedly connected to one side of the sampling container 1, a sampling assembly 7 is arranged on one side of the lifting assembly 6, a sampling tube 8 is fixedly connected to the sampling assembly 7, the sampling tube 8 extends into the interior of the sampling container 1, and its outlet position corresponds to the position of the storage components 5.

[0024] like Figure 3As shown, the drive assembly 3 includes a servo motor 9 fixedly connected to the bottom of the inner wall of the sampling tank 1, a first rotating gear 10 fixedly connected to the center of the rotating disk 4 near the bottom of the inner wall of the sampling tank 1, and a second rotating gear 11 fixedly connected to the output end of the servo motor 9. The second rotating gear 11 and the first rotating gear 10 mesh with each other.

[0025] like Figure 4 As shown, the storage assembly 5 includes a storage seat 12 fixedly connected to the upper surface of the rotating disk 4. A step is provided on the upper side wall of the storage seat 12. An ejector block 13 is fixedly connected at the corner of the step. The cross-section of the ejector block 13 is a right triangle, with the two right-angled sides corresponding to the two sides of the step. A cylinder 14 is fixedly connected to the inner wall of the rotating disk 4 corresponding to the ejector block 13. The output end of the cylinder 14 faces the ejector block 13, and a pusher block 15 is fixedly connected to the output end of the cylinder 14. The pusher block 15 and the inclined surface of the ejector block 13 cooperate with each other.

[0026] After sampling, the storage seat 12 needs to be removed from the rotating disk 4 to transfer the oil stored inside. This can be done by using cylinder 14 to move the push block 15 towards one side of the storage seat 12. During the movement of the push block 15, the inclined surfaces of the push block 15 and the ejector block 13 work together, applying an upward force to the storage seat 12, thus pushing it out of the rotating disk 4. This allows researchers to transfer the oil from the storage seat 12 to other containers for analysis.

[0031] During the operation of the device, the lifting motor 18 can drive the lead screw 17 to rotate. Since the lead screw 17 is threadedly connected to the sampling component 7, the sampling components 7 can move vertically upward or downward following the rotation direction of the lead screw 17, which is convenient for entering the formation at different depths to conduct oil sampling.

A lifting assembly 6 is fixedly connected to one side of the sampling container 1, a sampling assembly 7 is arranged on one side of the lifting assembly 6, a sampling tube 8 is fixedly connected to the sampling assembly 7, the sampling tube 8 extends into the interior of the sampling container 1, and its outlet position corresponds to the position of the storage components 5.

[0039] like Figure 3 As shown, the drive assembly 3 includes a servo motor 9 fixedly connected to the bottom of the inner wall of the sampling tank 1, a first rotating gear 10 fixedly connected to the center of the rotating disk 4 near the bottom of the inner wall of the sampling tank 1, and a second rotating gear 11 fixedly connected to the output end of the servo motor 9. The second rotating gear 11 and the first rotating gear 10 mesh with each other.

[0040] like Figure 4As shown, the storage assembly 5 includes a storage seat 12 fixedly connected to the upper surface of the rotating disk 4. A step is provided on the upper side wall of the storage seat 12. An ejector block 13 is fixedly connected at the corner of the step. The cross-section of the ejector block 13 is a right triangle, with the two right-angled sides corresponding to the two sides of the step. A cylinder 14 is fixedly connected to the inner wall of the rotating disk 4 corresponding to the ejector block 13.

The pusher block 15 and the inclined surface of the ejector block 13 cooperate with each other.

[0041] like Figure 5 As shown, the lifting assembly 6 includes a track frame 16 fixedly connected to one side of the sampling container 1. A lead screw 17 is fixedly connected inside the track frame 16. A lifting motor 18 is fixedly connected to the bottom end of the track frame 16. The output end of the lifting motor 18 is fixedly connected to one end of the lead screw 17. The lead screw 17 is threadedly connected to the sampling assembly 7.

[0042] like Figure 5 As shown, the sampling assembly 7 includes a connecting plate 19 fixedly connected to the lifting assembly 6. A sampling head 20 is fixedly connected to the bottom surface of the connecting plate 19, and a pump 21 is fixedly connected to the upper surface of the connecting plate 19. The input end of the pump 21 is connected to the sampling head 20, and the output end of the pump 21 is connected to the sampling tube 8.

[0043] like Figure 6 and Figure 7 As shown, a receiving platform 22 is fixedly connected between two adjacent storage components 5 on the rotating disk 4. The receiving platform 22 is a sloping structure with a high middle and low ends, and each end of the receiving platform 22 corresponds to a storage component 5.

[0044] like Figure 6 and Figure 7 As shown, each receiving platform 22 has a connecting rod 23 fixedly connected to the side corresponding to the rotating disk 4. The connecting rod 23 extends into the rotating disk 4 and is fixedly connected to a driven gear 24. Each driven gear 24 corresponding to the connecting rod 23 is meshed with a main gear 25. The main gear 25 is fixedly connected to a rotary motor 26.

[0045] When sampling, when a storage component 5 is full of oil, the rotating disk 4 needs to be rotated by the drive component 3 to switch different storage components 5. However, at this time, because the oil is relatively viscous, the oil in the sampling tube 8 is not completely discharged. When the rotating disk 4 rotates, the residual oil may drip onto the upper surface of the rotating disk 4, which increases the cleaning and maintenance cost of the device and may also contaminate the collected oil sample.

[0046] To solve the above problem, a receiving platform 22 is set between two adjacent storage components 5. The dripping oil will flow into the nearby storage component 5 under its own gravity. When cleaning, only the receiving platform 22 needs to be removed for cleaning, without cleaning the entire rotating disk.

[0047] In order to prevent the receiving platform 22 from affecting the removal of oil from the storage components 5, the driven gear 24 is driven by the main gear 25 through the rotary motor 26, so that the receiving platform 22 changes from connecting the two storage components 5 to being sandwiched between the two storage components 5, so as not to affect the removal of the storage components 5.

[0048] Workflow: First, the device is moved to the test location. Then, the lifting motor 18 is started to drive the lead screw 17 to rotate, thereby driving the connecting plate 19, along with the sampling head 20 and the pump 21, to move downward. When it reaches the designated position, the pump 21 is started to extract the oil in the formation into the sampling tank 1, and under the guidance of the sampling tube 8, it is transferred to the storage seat 12.

[0049] After one storage seat 12 is full, the servo motor 9 is started, which drives the rotating disk 4 to rotate through the first rotating gear 10 and the second rotating gear 11, moving the other storage seat 12 that has not stored oil to the bottom of the sampling tube 8 for collection.

[0050] When it is necessary to collect oil from different formations, after the current storage seat 12 is full, the pump 21 is first turned off to stop extracting oil. Then, the lifting motor 18 is started to move the sampling component 7 to other formations at different depths. After that, the servo motor 9 is started to switch the storage seat 12. Finally, the pump 21 is started to collect oil.

[0051] When sampling is completed and the sample needs to be removed from the sampling tank 1, first start the rotary motor 26 to change the position of the receiving platform 22 to avoid obstructing the storage seat 12, and then start the cylinder 14 to push the storage seat 12 out of the rotating disk 4, so that the staff can transfer the petroleum sample.
