Description

Technical Field

[0001] This utility model relates to the field of petroleum sampling technology, specifically to an oilfield sampler used for oilfield exploration. Background Technology

[0002] Existing oilfield samplers mainly consist of a mounting frame and a cap that allows for adjusting the seal of the sampling bottle. However, when the device moves the sampling bottle down to the sampling position and then the cap is no longer sealing the bottle, the bottle may float upwards due to the buoyancy of the oil, causing it to shift. This results in the cap not being able to seal properly with the bottle after sampling, thus affecting the reliability and accuracy of the sampling. Utility Model Content

[0003] The technical problem this invention aims to solve is that during the sampling process, the cap of the sampling bottle no longer seals with the bottle and rises, thus affecting the reliability and accuracy of the sampling.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an oilfield sampler for oilfield exploration, including a mounting frame and a sampling bottle. The mounting frame includes a mounting base plate and connecting columns on both sides of the mounting base plate. A U-shaped plate is hinged between the top ends of the connecting columns. A cap that can be slidably fitted with the sampling bottle is provided on the U-shaped plate. A clamping component that can limit the position of the sampling bottle is provided between the relative connecting columns. A counterweight is provided on the mounting base plate.

[0005] Furthermore, the clamping assembly includes a first clamping plate and a second clamping plate slidably disposed on the connecting post. The first clamping plate and the second clamping plate are disposed opposite to each other. The first clamping plate has a through hole on the side near the second clamping plate. The first clamping plate and the second clamping plate have sliding holes opposite to each other, and a first spring is disposed between the first clamping plate and the second clamping plate.

[0006] Furthermore, the first clamping plate and the second clamping plate are provided with an arc-shaped plate and a driving plate, the driving plate and the arc-shaped plate are concentric and opposite to each other, a connecting rod is provided between the arc-shaped plate and the driving plate, and a sliding hole is provided on the connecting rod.

[0007] Furthermore, the connecting column is provided with a fixing block, and the sliding hole is provided with a sliding groove that slides in cooperation with the fixing block.

[0008] Furthermore, the mounting base plate is provided with circumferential support feet at its bottom end.

[0009] Furthermore, a slide rod is slidably provided on the U-shaped plate, the bottom end of the slide rod is connected to a cover, a second spring is provided between the cover and the U-shaped plate and sleeved on the slide rod, and a drive ring is connected to the top end of the slide rod.

[0010] The advantages of this utility model compared with the prior art are as follows:

[0011] 1. The clamping assembly on the connecting column facilitates the clamping and limiting of the sampling bottle, preventing it from shifting due to the buoyancy of the oil during oil sampling;

[0012] 2. The counterweight allows the device to be smoothly and linearly lowered into the oil during the oil sampling process;

[0013] 3. The hinged design of the cap, U-shaped plate and connecting column facilitates the smooth introduction of the sampling bottle into the mounting frame and its positioning by the clamping component. It also allows the cap to seal the sampling bottle when the connecting column and U-shaped plate are collinear, so that it can be lowered to the sampling position. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Combined with appendix Figure 1An oilfield sampler for oilfield exploration includes a mounting frame 1 and a sampling bottle 2. The mounting frame 1 includes a mounting base plate 3 and connecting columns 4 on both sides of the mounting base plate 3. A U-shaped plate 5 is hinged between the top ends of the connecting columns 4. A cap 6 that can be slidably fitted on the U-shaped plate 5 to seal with the sampling bottle 2 is provided. A slide rod 20 is slidably provided on the U-shaped plate 5. The bottom end of the slide rod 20 is connected to the cap 6. A second spring 21 is provided between the cap 6 and the U-shaped plate 5 and sleeved on the slide rod 20. A drive ring 22 is connected to the top end of the slide rod 20.

[0022] The cap 6, through the action of the slide bar 20, the second spring 21, and the U-shaped plate 5, can seal with the sampling bottle 2 during the process of the device moving to the required sampling position, so as to avoid oil entering the sampling bottle 2 during the descent process, which would cause sampling mixing and inaccuracy.

[0023] When sampling is required:

[0024] First, the U-shaped plate 5 is at a certain angle to the connecting column 4 to make room for the sampling bottle 2, so that the sampling bottle 2 can be smoothly placed on the mounting base plate 3.

[0025] Then, by pulling the drive ring 22, the slide bar 20 is driven to slide the cover 6 upward, and the second spring 21 is compressed and stored.

[0026] Finally, the drive ring 22 drives the U-shaped plate 5 and the connecting column 4 to rotate around the hinge point until the U-shaped plate 5 and the connecting column 4 are collinear. At this time, the cap 6 is aligned with the sampling bottle 2. The drive ring 22 is slowly lowered, the second spring 21 gradually returns to its original position, and the slide rod 20 drives the cap 6 downward to seal with the top of the sampling bottle 2.

[0027] Combined with appendix Figure 1 Appendix Figure 3 and attached Figure 5 A clamping assembly 7 is provided between the connecting columns 4 to limit the position of the sampling bottle 2. The clamping assembly 7 includes a first clamping plate 9 and a second clamping plate 10 slidably disposed on the connecting columns 4. A fixing block 17 is provided on the connecting columns 4. An arc plate 14 and a driving plate 15 are provided on the first clamping plate 9 and the second clamping plate 10. The driving plate 15 and the arc plate 14 are concentric and opposite to each other. A connecting rod 16 is provided between the arc plate 14 and the driving plate 15. The first clamping plate 9 and the second clamping plate 10 are opposite to each other. A through hole 11 is provided on the side of the first clamping plate 9 near the second clamping plate 10. A sliding hole 12 is provided opposite to the connecting rod 16 of the first clamping plate 9 and the second clamping plate 10. A first spring 13 is provided between the first clamping plate 9 and the second clamping plate 10. A sliding groove 18 is provided on the sliding hole 12 to slide and cooperate with the fixing block 17.

[0028] Installation of sampling bottle 2:

[0029] First, by pressing the drive plates 15 on both sides closer together, the drive plates 15 drive the arc plates 14 away from each other through the connecting rod 16, and the first spring 13 is compressed and stores force.

[0030] Then, the sampling bottle 2 is passed between the arc plates 14 until the bottom wall of the sampling bottle 2 abuts against the mounting base plate 3;

[0031] Finally, the drive plate 15 is released, and under the reset action of the first spring 13, the two arc-shaped plates 14 move closer to each other to achieve center positioning of the sampling bottle 2 in the middle of the mounting base plate 3 so as to cooperate with the cap 6.

[0032] Combined with appendix Figure 2 and attached Figure 4 The mounting base plate 3 is provided with a support foot 19 around its bottom end, and a counterweight block 8 is provided on the mounting base plate 3.

[0033] The counterweight 8 facilitates the linear downward movement of the sampling bottle 2, making it easier to control the accuracy of the sampling position.
