Description

Technical Field

[0001] This utility model relates to the field of oilfield testing, and in particular to a sampling device for oilfield testing. Background Technology

[0002] During actual oil well production, sampling is sometimes performed through production valve ports or production pipeline interfaces. In this case, sampling is usually done to monitor information such as the composition, production rate, and flow rate of the oil and gas produced, so as to carry out production management and optimization.

[0003] Chinese Patent No. CN218349860U discloses a microbial sampling device for offshore oil fields, including a sampling device body. The outer front surface of the sampling device body is provided with scale lines. Sampling detection interface one and sampling detection interface two are respectively provided on the upper two sides of the sampling device body. One side of sampling detection interface one is connected to sampling port cover one through a connecting component one. The present invention is provided with sampling detection interface one and sampling detection interface two, which can facilitate the delivery of oil and water samples and inert gas into the sampling device body.

[0004] While the above technology can facilitate the delivery of oil and water samples and inert gas into the sampling device, multiple batches of sampling are required when sampling at the production valve port. This makes the operation more complicated by repeatedly picking up and placing the sample bottle, and it is inconvenient to hold the sample bottle up all the time. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sampling device for oilfield testing, which aims to improve the problem of complex multiple sampling operations in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An oilfield sampling device includes a connecting plate, an oil storage tank fixedly connected to the lower part of the connecting plate, a measuring tape fixedly connected to the front side of the oil storage tank, end caps fixedly connected to the upper parts of both ends of the oil storage tank, an I-beam block slidably connected inside the connecting plate, a slot provided on the side end of the connecting plate, an overlapping block fixedly connected to the side wall of the I-beam block, a locking block elastically connected to both ends of the overlapping block by a first spring, a protrusion fixedly connected to the upper end of the locking block, and a sealing component slidably connected to the top of the oil storage tank.

[0008] The sealing assembly includes an inclined block, a sealing plate is fixedly connected to the lower part of the inclined block, the side end of the sealing plate is elastically connected to the top of the oil reservoir by a second spring, and a sealing strip is in contact with the lower part of the sealing plate.

[0009] One end of the first spring is fixedly connected to the inside of both ends of the overlapping block, and the other end of the first spring is fixedly connected to the side of the locking block.

[0010] The lower end of the card block is slidably connected to the inside of the card slot.

[0011] The external sliding connection of the protrusion is on the upper inner end of both ends of the overlapping block.

[0012] The lower side of the inclined block is in contact with the upper part of the oil storage tank.

[0013] One end of the second spring is fixedly connected to the inside of the upper end of the oil reservoir, and the other end of the second spring is fixedly connected to the outside of the side end of the sealing plate.

[0014] The sealing strip is externally fixedly connected to the upper inner part of the oil reservoir.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model allows the locking block to slide out of the slot by sliding the protrusions at both ends. Then, the oil storage cylinder can slide up and down to connect and separate from the valve port and keep its position fixed. This eliminates the need to repeatedly pick up and put down the sample bottle, thus increasing the convenience of multiple samplings. It also eliminates the need for continuous lifting and makes it convenient to close and open the valve port.

[0017] 2. This utility model allows the sealing plate to slide to both ends by the pressure of the inclined block on the valve port, which can open the oil storage tank to the left and right. When the oil storage tank slides down, the second spring can quickly close the sealing plate by pressing it, eliminating the need for separate opening and closing of the oil storage tank and improving work efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2 A sampling device for oilfield testing includes a connecting plate 1. The connecting plate 1 can drive the oil storage cylinder 4 to slide up and down, and the oil storage cylinder 4 is fixed at different heights for sampling and placement. The lower part of the connecting plate 1 is fixedly connected to the oil storage cylinder 4. The oil storage cylinder 4 can collect oil and water samples sprayed from the valve. The front side of the oil storage cylinder 4 is fixedly connected to a measuring scale 2, which can observe the volume of oil and water samples inside the oil storage cylinder 4.

[0025] The upper part of both ends of the oil storage tank 4 is fixedly connected with end caps 3. The oil storage tank 4 has oil outlets at both ends that can be closed by the end caps 3. The connecting plate 1 has an I-shaped block 9 that is slidably connected inside. The I-shaped block 9 is restricted by the connecting plate 1 to slide vertically within a fixed distance, so that the overlapping block 5 can be connected by the connecting plate 1.

[0026] The side end of the connecting plate 1 is provided with a slot 10. By fixing the block 7 inside the slots 10 at the upper and lower ends, the oil storage cylinder 4 can be kept in the sampling position and the closed position. This eliminates the need for repeated picking and placing, and also eliminates the need to hold the cylinder up during sampling, making it convenient to open and close the valve.

[0027] Reference Figures 1-2 An overlapping block 5 is fixedly connected to the side wall of the I-beam block 9. The overlapping block 5 is U-shaped with an arc-shaped upper end, which allows the entire device to be overlapped at the valve port for easy sampling. The two ends of the overlapping block 5 are elastically connected to the locking block 7 by the first spring 8. The first spring 8 can press the locking block 7 to fix it inside the locking groove 10, and the locking block 7 is restricted by the overlapping block 5 to slide only relatively horizontally within a fixed distance. One end of the first spring 8 is fixedly connected to the two ends of the overlapping block 5, and the other end of the first spring 8 is fixedly connected to the side of the locking block 7. The first spring 8 is pressed by the overlapping block 5 to keep the locking block 7 in a compressed state.

[0028] The lower end of the locking block 7 is slidably connected to the inside of the slot 10. The upper end of the locking block 7 is fixedly connected to the protrusion 6. The protrusion 6 can easily drive the locking blocks 7 at both ends to slide out of the inside of the slot 10. The protrusion 6 is slidably connected to the upper end of the inside of both ends of the overlapping block 5. The overlapping block 5 restricts the protrusion 6 to slide horizontally in a straight line. The top of the oil reservoir 4 is slidably connected to the sealing component.

[0029] Reference Figure 1 and Figure 3 The sealing component includes an inclined block 13, which can be squeezed to drive the sealing plates 12 at both ends to slide to both ends, so that the upper end of the oil storage tank 4 can be opened. This eliminates the need to repeatedly rotate the oil storage tank 4 to open and close, increasing the ease of operation.

[0030] The lower side of the inclined block 13 is in contact with the upper part of the oil reservoir 4. A sealing plate 12 is fixedly connected to the lower part of the inclined block 13. The sealing plate 12 can seal the upper end of the oil reservoir 4. The side of the sealing plate 12 is elastically connected to the inside of the top of the oil reservoir 4 by the second spring 11. The second spring 11 can press the sealing plate 12 to slide towards the middle position, so that the oil reservoir 4 is sealed.

[0031] One end of the second spring 11 is fixedly connected to the inside of the upper end of the oil reservoir 4, and the other end of the second spring 11 is fixedly connected to the outside of the side end of the sealing plate 12. The compression of the second spring 11 can keep the sealing plates 12 closed and prevent them from sliding. The lower part of the sealing plate 12 contacts the sealing strip 14. The outside of the sealing strip 14 is fixedly connected to the upper end of the inside of the oil reservoir 4. The sealing strip 14 can keep the upper end of the oil reservoir 4 sealed and prevent contamination.

[0032] Working principle: After the waste oil is discharged from the valve port, the overlapping block 5 is overlapped at the valve port, and then the protrusion 6 is slid towards the middle. The protrusion 6 drives the locking block 7 to slide towards the middle. The lower part of the locking block 7 slides out of the inside of the locking groove 10, and the locking block 7 squeezes the first spring 8. Then the oil storage cylinder 4 can slide up. The oil storage cylinder 4 drives the connecting plate 1 to slide up, and releases the protrusion 6 when sliding up.

[0033] When the valve is pressed upward, the inclined block 13 slides to both ends. The inclined block 13 drives the two end sealing plates 12 to slide to both ends. The sealing plates 12 press the second spring 11, causing the oil reservoir 4 to open. When the oil reservoir 4 slides upward to a certain height, the lower end of the locking block 7 slides in under the pressure of the first spring 8.

[0034] The oil reservoir 4 is fixed relative to the overlapping block 5 inside the lower end slot 10 of the connecting plate 1. At this time, the valve is opened to discharge oil. The volume of the oil-water sample is observed through the measuring tape 2. Then the valve is closed, and the protrusion 6 is slid towards the middle to drive the locking block 7 out of the slot 10. Then the oil reservoir 4 is slid down to its original position. The protrusion 6 is released so that the locking block 7 slides into the upper end slot 10 under the pressure of the first spring 8. At this time, the second spring 11 presses the sealing plate 12 to slide to its original position, so that the upper end of the oil reservoir 4 is sealed. After waiting for three to five minutes, the sample is taken again until a suitable number of samples are obtained. Then the whole device is slid out.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
