[0002] During oil extraction, the crude oil extracted by the pumping unit is generally composed of a mixture of crude oil, water, and natural gas. In order to obtain water production data from the oil well and to use this data to estimate crude oil production, oil-producing layers, predict the development life of the oil well, control the production and quality of the oil well, monitor the condition of the oil well, and carry out water injection operations, etc., the staff will separate the natural gas and crude oil from the crude oil and test the water content of the crude oil so that the staff can understand the water production data of the oil well.

[0003] When measuring, natural gas can be separated naturally, while crude oil and water are mixed together and need to be separated by permeation, evaporation and other methods to obtain data on the oil-water ratio. In this case, a certain amount of crude oil needs to be weighed in advance, then the water needs to be separated, and finally the crude oil after water separation needs to be weighed to obtain the water content ratio in the crude oil. The detection process is relatively complicated.

[0004] Therefore, this application proposes a multifunctional metering and detection device to improve the convenience of detecting the oil-water ratio in oil-water mixtures. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a multifunctional metering and detection device to solve the problem of inconvenience in detecting oil and water content mentioned in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a multifunctional measuring and testing device, including a weight measuring part, a protective cover provided on the edge of the upper surface of the weight measuring part, and a raw material storage container provided on the upper surface of the weight measuring part;

[0007] The protective cover is provided with a pressure-applying part, which is coaxial with the raw material storage container. The output end of the pressure-applying part is provided with a separation part. The pressure-applying part is used to drive the separation part into the interior of the raw material storage container to apply pressure to the material inside the raw material storage container.

[0008] The separation section includes a separation cylinder, the outer diameter of which is equal to the inner diameter of the raw material storage vessel, and a dialysis membrane is provided at the bottom of the separation cylinder.

[0009] Preferably, the top of the weighing unit is provided with a limiting barrier, the inner diameter of which is adapted to the outer diameter of the raw material storage container, and the bottom of the outer surface of the raw material storage container is inserted into the limiting barrier.

[0010] Preferably, the pressure-applying part includes an electric push rod, and a relay connector is provided between the electric push rod and the separation part, the relay connector being detachable from both the electric push rod and the separation part.

[0011] Preferably, the relay connector includes a shaft, one end of which is provided with an external thread, and the other end of which is provided with a threaded hole, wherein the external thread is threadedly connected to the end of the electric push rod;

[0012] The separator cylinder has a threaded rod at its axis, and the threaded rod is threadedly connected to a threaded hole.

[0013] Preferably, the dialysis membrane is located between the inner wall of the separation cylinder and the outer surface of the threaded rod, and the lower end of the outer surface of the threaded rod is provided with a keel, which penetrates the interlayer of the dialysis membrane and connects to the inner wall of the separation cylinder.

[0014] Preferably, the interior of the protective cover is provided with an oil-removing section that abuts against the outer surface of the separation section.

[0019] As described above, the multifunctional metrological testing device of this utility model has the following beneficial effects:

[0020] 1. This utility model pre-weighs the crude oil by setting a weight measuring unit, and then the electric push rod drives the separation cylinder to descend and apply pressure to the crude oil in the raw material storage container. Under the pressure, small water molecules pass through the dialysis membrane and are separated from the crude oil in the separation cylinder. After the water is separated, the electric push rod causes the separation cylinder to detach from the raw material storage container, and the crude oil in the raw material storage container is weighed again. The proportion of water in the crude oil is calculated by the weight difference, which improves the convenience of detecting the water content in crude oil.

[0021] 2. This utility model improves the accuracy of detection by setting a support rod in the protective cover to support the scraper cylinder and setting the scraper cylinder and the separation cylinder concentrically. As the separation cylinder rises from the raw material storage container, the scraper cylinder scrapes off the crude oil attached to the outer surface of the separation cylinder and causes the scraped crude oil to fall back into the interior of the raw material storage container.

[0022] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0035] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0036] Please see Figures 1 to 6It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0037] like Figure 1 and Figure 3 As shown, this utility model provides a multifunctional measuring and testing device, including a weight measuring section 1. An electronic measuring plate with a set weight is provided at the center of the upper surface of the weight measuring section 1. A protective cover 12 is provided at the edge of the upper surface of the weight measuring section 1. A transparent partition is provided around the protective cover 12 to facilitate observation of the internal condition of the protective cover 12. A raw material storage container 2 is provided on the upper surface of the weight measuring section 1. The raw material storage container 2 is placed on the electronic measuring plate. When crude oil to be measured is placed inside the raw material storage container 2, the weight of the crude oil is measured by the weight measuring section 1.

[0038] The protective cover 12 is provided with a pressure-applying part 3, which is coaxial with the raw material storage container 2. The output end of the pressure-applying part 3 is provided with a separation part 4. The pressure-applying part 3 is used to drive the separation part 4 into the interior of the raw material storage container 2 to apply pressure to the material inside the raw material storage container 2.

[0039] The separation section 4 includes a separation cylinder 41, which is made of corrosion-resistant metal. The outer diameter of the separation cylinder 41 is equal to the inner diameter of the raw material storage vessel 2. When the separation cylinder 41 enters the raw material storage vessel 2, it can prevent substances in the raw material storage vessel 2 from seeping out from the connection between the raw material storage vessel 2 and the separation cylinder 41. The bottom of the separation cylinder 41 is provided with a dialysis membrane 43. The crude oil is pressurized by the combination of the separation cylinder 41 and the dialysis membrane 43. Small water molecules are dialyzed through the dialysis membrane 43 to the separation cylinder 41 and separated from the crude oil.

[0040] like Figure 1 and Figure 2As shown, in some embodiments, the top of the weight measuring part 1 of this utility model is provided with a limiting barrier 11. The inner diameter of the limiting barrier 11 is adapted to the outer diameter of the raw material storage container 2. The bottom of the outer surface of the raw material storage container 2 is inserted into the limiting barrier 11. When the separating cylinder 41 applies pressure to the crude oil inside the raw material storage container 2, the limiting barrier 11 can prevent the raw material storage container 2 from shifting or popping out under pressure, thereby improving the stability and safety of the detection.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, the pressure application part 3 of this utility model includes an electric push rod 31, and a relay connector 32 is provided between the electric push rod 31 and the separation part 4. The relay connector 32 can be separated from the electric push rod 31 and the separation part 4 respectively. By changing the length of the relay connector 32, the extension and retraction of the electric push rod 31 can be adapted to raw material storage containers 2 of different depths and crude oil of different volumes, thereby improving the adaptability of the equipment.

[0042] like Figure 4 As shown, in some embodiments, the relay connector 32 of this utility model includes a shaft 321, which is a smooth metal rod. One end of the shaft 321 is provided with an external thread 322, which is threadedly connected to the end of the electric push rod 31, so that the shaft 321 can be separated from the electric push rod 31. The other end of the shaft 321 is provided with a threaded hole 323, and the axis of the separating cylinder 41 is provided with a threaded rod 42, which is threadedly connected to the threaded hole 323, so that the shaft 321 can be separated from the separating cylinder 41, which is used to facilitate the disassembly of the separating cylinder 41 to measure the weight of the moisture in the separating cylinder 41. During measurement, the moisture weight can be measured by directly placing the separating cylinder 41 containing moisture on the weight measuring part 1.

[0043] like Figure 3 As shown, in some embodiments, the dialysis membrane 43 of this invention is located between the inner wall of the separation cylinder 41 and the outer surface of the threaded rod 42. The lower end of the outer surface of the threaded rod 42 is provided with a keel. The keel penetrates the interlayer of the dialysis membrane 43 and connects to the inner wall of the separation cylinder 41. The keel supports the dialysis membrane 43 to improve the strength of the dialysis membrane 43 and prevent the dialysis membrane 43 from being over-pressurized and damaged when it applies pressure to crude oil.

[0044] like Figure 5 As shown, in some embodiments, the protective cover 12 of this utility model is provided with an oil-cleaning part 5 that abuts against the outer surface of the separation part 4. When the separation cylinder 41 enters the raw material storage container 2 to pressurize the crude oil, crude oil will adhere to the outer surface of the separation cylinder 41, causing the amount of crude oil in the raw material storage container 2 to decrease, thereby resulting in inaccurate measurement data. At this time, the oil-cleaning part 5 is used to scrape the crude oil adhering to the outer surface of the separation cylinder 41 into the raw material storage container 2, thereby improving the measurement accuracy.

[0045] like Figure 5 and Figure 6 As shown in some embodiments, the oil cleaning part 5 of this utility model includes a support rod 51 and a scraper 52. The scraper 52 is concentrically arranged with the separation cylinder 41. One end of the support rod 51 is connected to the protective cover 12, and the other end of the support rod 51 is connected to the outer surface of the scraper 52. It is used to support the scraper 52 and keep the scraper 52 in a suspended state. During the lifting and lowering process of the separation cylinder 41, the inner diameter of the scraper 52 is in contact with the outer surface of the separation cylinder 41, thereby scraping away the crude oil on the outer surface of the separation cylinder 41.

[0046] like Figure 6 As shown, in some embodiments, the top of the inner diameter of the scraper 52 of this utility model is provided with a flow guide chamfer 53. When the scraper 52 scrapes the separator 41, some crude oil will adhere to the inside of the scraper 52 as the separator 41 rises and falls. At this time, the flow guide chamfer 53 can store the crude oil attached to the inner wall of the support rod 51, and after the separator 41 leaves the inside of the scraper 52, it falls into the inside of the raw material storage container 2 along the flow guide chamfer 53.

[0047] It is worth mentioning that the outer surface of the separating cylinder 41 is smooth and the inner wall of the scraper cylinder 52 is smooth, in order to reduce the friction when the separating cylinder 41 enters and exits the inner wall of the scraper cylinder 52, thereby improving the service life of the equipment.

[0048] In summary, the multifunctional metering and testing device of this utility model pre-weighs the crude oil by setting a weight metering unit 1, and then the electric push rod 31 drives the separation cylinder 41 to descend and apply pressure to the crude oil in the raw material storage container 2. Under the action of pressure, small water molecules are dialyzed through the dialysis membrane 43 into the separation cylinder 41 and separated from the crude oil. After the water is separated, the electric push rod 31 causes the separation cylinder 41 to detach from the raw material storage container 2, and the crude oil in the raw material storage container 2 is weighed again. The proportion of water in the crude oil is calculated by the weight difference, thereby improving the convenience of detecting the water content in crude oil.

[0049] This invention improves detection accuracy by providing a support rod 51 in the protective cover 12 to support the scraper cylinder 52 and setting the scraper cylinder 52 and the separation cylinder 41 concentrically. As the separation cylinder 41 rises from the raw material storage container 2, the scraper cylinder 52 scrapes off the crude oil adhering to the outer surface of the separation cylinder 41 and causes the scraped crude oil to fall back into the interior of the raw material storage container 2.

[0050] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0051] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
