Description

Technical Field

[0001] The utility model belongs to the technical field of tracer sampling, in particular to a tracer monitoring sampling device. Background Art

[0002] With the deepening of oil field development, reservoir development has entered the medium-to-high water content stage. The monitoring of oil wells is an important guarantee to ensure the high-efficiency development of oil fields. Inter-well tracer monitoring is a monitoring method for oil wells. A water-soluble tracer is injected into the injection well, and water samples are taken from the surrounding monitoring wells. The concentration of the tracer in the water sample is analyzed, and the tracer output curve is drawn. The tracer interpretation software is used to analyze the tracer output curve, and the heterogeneity of the reservoir can be determined. When the existing tracer sampling device is used, the size of the external pipeline is different for different external environments, and it is more troublesome to assemble and inconvenient to install quickly. In addition, the collection tube is prone to damage after long-term use. After the collection tube is damaged, it needs to be replaced as a whole, and the replacement cost is relatively high. In addition, when the device is used, the installation position spacing is different for different external environments, and the overall length is not convenient to adjust.

[0003] In order to solve the above problems, a tracer sampling device is proposed in a Chinese patent with publication number CN220304834U. When the device is used, after the length adjustment is completed, a suitable first flange or second flange is selected to correspond to the external pipeline for installation. After the overall installation, the valve at the appropriate position is opened, and the components in the pipeline enter the hose through the three-way pipe, enter the fixed pipe through the hose, and enter the collecting pipe through the fixed pipe to realize the sampling operation. After the device is used for a long time, the collecting tube is damaged and the collecting tube is replaced. The adjusting rod is rotated, the adjusting rod rotates relative to the fixed block, the adjusting rod and the adjusting hole are threadedly matched, the guide rod and the guide hole are matched for guidance, and the movable seat slides relative to the fixed seat. After sliding to the appropriate distance, the collecting tube is replaced, and the mounting tube of the new collecting tube is installed corresponding to the mounting hole on the fixed seat. The adjusting rod is rotated in the opposite direction, the sliding seat slides to the left, and the fixed seat and the sliding seat cooperate to lock the collection tube installation.

[0004] The disadvantage is that the sampling device is a multi-use product. Since the installation tube needs to be repeatedly placed in the installation hole, such frequent operations will inevitably cause wear and tear on both and create gaps, leading to oil leakage, which reduces the sealing and service life of the sampling device. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model solves the problem in the comparative document that the installation tube needs to be repeatedly inserted into the installation hole. Such frequent operations will inevitably cause wear and tear between the two and create gaps, thereby causing oil leakage, thereby improving the sealing and service life of the sampling device.

[0006] The technical solution adopted by the utility model is as follows: the utility model proposes a tracer monitoring sampling device, including a collecting device and a fixing device;

[0007] The collecting device comprises a collecting tube, which is cylindrical;

[0008] The collecting tube is used to collect oil samples, and the fixing device is movably connected to both ends of the collecting tube;

[0009] The collecting device also includes a mounting tube and a rubber layer;

[0010] The collecting tube is a hollow structure, and two ends of the collecting tube are coaxially fixedly connected to two mounting tubes, and the inner walls of the two mounting tubes are fixedly connected to the rubber layer;

[0011] The fixing device comprises a fixing seat, a water pipe, a sealing pipe and an installation cavity;

[0012] The fixing seat is cylindrical and has two fixing seats;

[0013] The surfaces of the two fixing seats close to the collecting pipe are coaxially fixedly connected to two water pipes, and the water pipes penetrate the fixing seats;

[0014] The surfaces of the two fixing seats close to the collecting pipe are fixedly connected to two annular sealing pipes, and the inner diameter of the sealing pipe is larger than the outer diameter of the water pipe;

[0015] An installation cavity is arranged between the sealing tube and the water pipe on each fixing seat, and the installation tube is slidably connected with the installation cavity.

[0016] Furthermore, the fixing device also includes a guide block, a guide rod, a limit block, a threaded rod, a through hole, and a threaded hole;

[0017] The side walls of the two fixing seats are symmetrically fixedly connected to two guide blocks, the surfaces of the two guide blocks on one fixing seat close to the other fixing seat are fixedly connected to a cylindrical guide rod, and the surfaces of the two guide blocks on the other fixing seat close to the guide rod are correspondingly provided with a through hole, and the through hole is slidably connected to the guide rod;

[0018] The two side walls of the fixing seat are fixedly connected to a limiting block, the two limiting blocks are provided with threaded holes, and the two threaded holes are threadably matched with the same threaded rod.

[0019] Furthermore, surfaces of the two fixing seats that are away from each other are coaxially fixedly connected to a connecting pipe, and ends of the two connecting pipes that are away from each other are fixedly connected to a first connecting flange.

[0020] Further, the tracer monitoring sampling device also includes a deformation device;

[0021] The deformation device includes a hose and a second connecting flange;

[0022] The surfaces of the two first connecting flanges which are away from each other are each movably connected to a second connecting flange;

[0023] The surfaces of the two second connecting flanges that are away from each other are coaxially fixed to the hose;

[0024] Both ends of the two hoses are fixedly connected to a second connecting flange.

[0025] Furthermore, each of the surfaces of the second connecting flanges that are away from each other is movably connected to a tee pipe;

[0026] The three ends of the two tee pipes are all fixedly connected to a third connecting flange.

[0027] Furthermore, the collecting device also includes a sealing gasket;

[0028] The inner wall of the rubber layer is fixedly connected with a plurality of sealing gasket groups at equal intervals, and each sealing gasket group is composed of two sealing gaskets with semicircular arc cross-sections;

[0029] The sealing pads are all made of rubber.

[0030] Furthermore, the collecting device also includes a soft magnetic sheet;

[0031] The inner cavities of the two sealing pads in each sealing pad group that are close to each other are provided with soft magnetic sheets.

[0032] The beneficial effects achieved by the utility model using the above structure are as follows:

[0033] Firstly, by coaxially fixing the water pipe and the sealing pipe on the fixing seat, the installation cavity formed between the two provides precise limiting and guiding for the installation pipe; when the installation pipe is inserted into the installation cavity, the water pipe and the sealing pipe not only ensure the accuracy of the installation process, but also effectively reduce the friction and wear during the installation process through their structural characteristics; the rubber layer fixedly connected to the inner wall of the installation pipe not only effectively prevents the oil sample leakage caused by the wear that may be caused by the direct contact between the installation pipe and the water pipe, but also enhances the overall sealing performance, ensures the safe collection of oil samples, and improves the overall sealing and installation efficiency of the tracer sampling device.

[0034] Secondly, when the mounting tube is inserted into the mounting cavity, each sealing gasket will be deformed under the squeezing action of the water pipe, and will fit tightly with the rubber layer on the inner wall of the mounting cavity, thereby achieving a high degree of sealing between the mounting tube and the water pipe, which not only enhances the stability of the structure, but also ensures the safety of the oil sample during the collection process; when the collection tube needs to be replaced and the mounting tube is pulled out of the mounting cavity, the two sealing gaskets in the sealing gasket group will quickly restore their original semicircular shape due to their own elasticity, approach each other and fit tightly together, avoiding leakage of the oil sample during the disassembly process, thereby ensuring the operational safety and data accuracy of the tracer sampling device when replacing the collection tube.

[0035] Thirdly, when the collection tube needs to be replaced, the installation tube is pulled out of the installation cavity. At this time, the two sealing gaskets in the sealing gasket group will quickly return to their original semicircular arc shape due to their own elasticity. Since the soft magnetic sheets in the inner cavities of the two sealing gaskets have magnetic effects, they will attract each other, thereby driving the two sealing gaskets to fit more closely together. This magnetic effect not only speeds up the closing speed of the sealing gaskets, but also enhances the sealing performance between the two sealing gaskets. Through this improvement, the risk of oil sample leakage during the disassembly and replacement of the collection tube of the collection device is greatly reduced, which not only ensures the accuracy of the tracer monitoring data, but also improves the safety and reliability of the entire sampling process.

[0054] The fixing device 200 includes a fixing seat 210, a water pipe 220, a sealing pipe 230, and an installation cavity 240;

[0055] The fixing seat 210 is cylindrical, and there are two fixing seats 210;

[0056] The surfaces of the two fixing seats 210 close to the collecting pipe 220 are coaxially fixedly connected to two water pipes 220, and the water pipes 220 penetrate the fixing seats 210;

[0057] The surfaces of the two fixing seats 210 close to the collecting pipe 220 are fixedly connected to two annular sealing pipes 230, and the inner diameter of the sealing pipe 230 is larger than the outer diameter of the water pipe 220;

[0058] An installation cavity 240 is provided between the sealing tube 230 and the water pipe 220 on each of the fixing seats 210 , and the installation tube 120 is slidably connected to the installation cavity 240 .

[0059] Furthermore, the fixing device 200 further includes a guide block 250, a guide rod 260, a limit block 270, a threaded rod 280, a through hole 290, and a threaded hole 211;

[0060] The side walls of the two fixing seats 210 are symmetrically fixedly connected to two guide blocks 250, wherein the surfaces of the two guide blocks 250 on one fixing seat 210 close to the other fixing seat 210 are fixedly connected to a cylindrical guide rod 260, and the surfaces of the two guide blocks 250 on the other fixing seat 210 close to the guide rod 260 are correspondingly provided with a through hole 290, and the through hole 290 is slidably connected to the guide rod 260;

[0061] The side walls of the two fixing seats 210 are fixedly connected to a limiting block 270 . The two limiting blocks 270 are provided with threaded holes 211 . The two threaded holes 211 are threadedly matched with the same threaded rod 280 .

[0062] Furthermore, the surfaces of the two fixing seats 210 that are away from each other are coaxially fixedly connected to a connecting pipe 300 , and the ends of the two connecting pipes 300 that are away from each other are fixedly connected to a first connecting flange 400 .

[0063] Furthermore, the tracer monitoring sampling device further includes a deformation device 500;

[0064] The deformation device 500 includes a hose 510 and a second connecting flange 520;

[0065] The surfaces of the two first connecting flanges 400 that are away from each other are both movably connected to a second connecting flange 520;

[0066] The surfaces of the two second connecting flanges 520 that are away from each other are coaxially fixed with the hose 510;

[0067] Both ends of the two hoses 510 are fixedly connected to a second connecting flange 520 .

[0068] Furthermore, each of the surfaces of the second connecting flanges 520 that are away from each other is movably connected to a three-way pipe 600;

[0069] The three ends of the two three-way pipes 600 are fixedly connected to a third connecting flange 700 .

[0070] During specific use, the operator first fixes the tee pipe 600 to the oil pipeline through the third connecting flange 700, connects the tee pipe 600 and the hose together through the connection between the second connecting flange 520 and the third connecting flange 700, and then connects the fixing device 200 and the hose 510 through the connection and cooperation between the second connecting flange 520 and the first connecting flange 400; puts the collecting pipe 110 between the two fixing seats 210, inserts the mounting pipes 120 at both ends of the connecting pipe 110 into the two mounting cavities 240, and then pushes the two guide rods 260 into the through holes 290 to align the positions of the two fixing seats 210, and then fixes the collecting pipe 110 with the fixing device 100 through the threaded cooperation between the threaded rod 280 and the two threaded holes 211, and finally opens the oil pipeline to realize the collection of oil samples by the collecting pipe 110.

[0071] Beneficial effect: By coaxially fixing the water pipe 220 and the sealing tube 230 on the fixing seat 210, the installation cavity 240 formed therebetween provides precise positioning and guidance for the installation tube 120; when the installation tube 120 is inserted into the installation cavity 240, the water pipe 220 and the sealing tube 230 not only ensure the accuracy of the installation process, but also effectively reduce the friction and wear during the installation process through their structural characteristics; the rubber layer 130 fixedly connected to the inner wall of the installation tube 120 not only effectively prevents the oil sample leakage caused by the wear that may be caused by the direct contact between the installation tube 120 and the water pipe 220, but also enhances the overall sealing performance, ensures the safe collection of oil samples, and improves the overall sealing performance and installation efficiency of the tracer sampling device.

[0072] Embodiment 2

[0073] When the collection tube 110 needs to be replaced after the oil sample is collected, the operator cannot immediately block the installation tube 120 after the installation tube 120 is pulled out of the installation cavity 240, causing the oil sample in the collection tube 110 to flow out, thereby affecting the monitoring accuracy of the tracer. Therefore, Example 2 further improves Example 1.

[0074] like Figure 7 and Figure 8 As shown, the collecting device 100 further includes a sealing gasket 140;

[0075] The inner wall of the rubber layer 130 is fixedly connected with a plurality of sealing gasket groups at equal intervals, and each sealing gasket group is composed of two sealing gaskets 140 with a semicircular arc cross section;

[0076] The sealing pads 140 are all made of rubber.

[0077] When the mounting tube 120 is inserted into the mounting cavity 240, each sealing gasket 140 will be deformed under the squeezing action of the water passing pipe 220, and will fit tightly with the rubber layer 130 against the inner wall of the mounting cavity 240, thereby achieving a high degree of sealing between the mounting tube 120 and the water passing pipe 220, which not only enhances the stability of the structure, but also ensures the safety of the oil sample during the collection process; when the collection tube 110 needs to be replaced and the mounting tube 120 is pulled out of the mounting cavity 240, the two sealing gaskets 140 in the sealing gasket group will quickly restore their original semicircular shape due to their own elasticity, approach each other and fit tightly together, thereby avoiding leakage of the oil sample during the disassembly process, thereby ensuring the operational safety and data accuracy of the tracer sampling device when replacing the collection tube 110.

[0078] Embodiment 3

[0079] In order to further improve the sealing and leak-proof effects of the sealing gasket assembly during the disassembly and replacement of the collecting tube 110, the third embodiment further improves the second embodiment.

[0080] like Fig. 9 As shown, the collecting device 100 further includes a soft magnetic sheet 150;

[0081] A soft magnetic sheet 150 is provided in the inner cavities of the two sealing gaskets 140 in each sealing gasket group that are close to each other.

[0082] When the collecting tube 110 needs to be replaced, the mounting tube 120 is pulled out of the mounting cavity 240. At this time, the two sealing gaskets 140 in the sealing gasket group will quickly return to their original semicircular arc shape due to their own elasticity. Since the soft magnetic sheets 150 in the inner cavities of the two sealing gaskets 140 have magnetic effects, they will attract each other, thereby driving the two sealing gaskets 140 to fit more closely together. This magnetic effect not only speeds up the closing speed of the sealing gaskets, but also enhances the sealing performance between the two sealing gaskets 140. Through this improvement, during the process of disassembling and replacing the collecting tube 110 of the collecting device 100, the risk of oil sample leakage is greatly reduced, which not only ensures the accuracy of the tracer monitoring data, but also improves the safety and reliability of the entire sampling process.

[0084] 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.

[0085] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
