Description

Technical Field

[0001] The invention relates to the technical field of sand washing, in particular to a petroleum geological logging sand washing device. Background Art

[0002] Geological logging is a wellbore exploration technology that integrates geology, electronic machinery, chemical analysis, and computers. It collects, organizes, and analyzes a large amount of primary information during the drilling process, establishes stratigraphic profiles while drilling, discovers and evaluates oil and gas reservoirs, and facilitates safe drilling and protection of oil and gas reservoirs. Geological logging drilling also produces a large amount of mud and sand, which must be cleaned to remove impurities in order to be used.

[0003] Existing sand washing devices are divided into wheel sand washing machines and spiral sand washing machines. Compared with spiral sand washing machines, wheel sand washing machines occupy a smaller area and have a lower loss rate during sand washing, but the cleaning degree is lower, and the moisture content after sand washing is higher, which increases the dehydration time. In addition, the fine impurities in the sand can easily clog the water filter holes connected to the sand storage pool, making it difficult to discharge water.

[0004] In view of the above problems, the present invention provides a petroleum geological logging sand washing device to solve the above problems. Summary of the Invention

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a petroleum geological logging sand washing device, comprising:

[0006] A sand washing tank is provided with a feed port on one side and a discharge guide plate on the other side, and a drain port is fixed on the bottom of the sand washing tank near the discharge guide plate;

[0007] A driving assembly is symmetrically fixed to the inner wall of the sand washing tank;

[0008] An inner cylinder is fixed between the two driving assemblies and is provided with a plurality of water filtering holes;

[0012] Oscillating components are arranged circumferentially on the central axis and are close to the reset component; and

[0013] A cleaning rod is fixed to one end of the oscillating component away from the central axis.

[0014] Furthermore, preferably, the driving assembly includes:

[0019] There is at least one linkage gear, which is rotatably disposed between the first fixed disk and the second fixed disk and is meshed with the outer gear and the inner gear for transmission.

[0020] Furthermore, preferably, the reset component includes:

[0021] an oscillating plate, fixed on the second fixed plate;

[0022] Reset frames, at least three in number, circumferentially fixed to the oscillating disk;

[0032] Furthermore, preferably, the elasticity of the reset spring is greater than the elasticity of the oscillation spring, so as to facilitate the resetting of the oscillation rod.

[0033] Compared with the prior art, the present invention provides a petroleum geological logging sand washing device, which has the following beneficial effects:

[0039] Reference Figures 1 to 3 The present invention provides a technical solution: a petroleum geological logging sand washing device, comprising:

[0040] The sand washing tank 1 has a feed port 12 on one side and a discharge guide plate 11 on the other side. A drain port 13 is fixed to the bottom of the sand washing tank 1 near the discharge guide plate 11.

[0041] The driving assembly 2 is symmetrically fixed on the inner wall of the sand washing tank 1;

[0042] The inner cylinder 3 is fixed between the two driving components 2 and is provided with a plurality of water filtering holes;

[0043] The bucket wheel 4 is fixed to the outer wall of the inner cylinder 3 and has multiple sand storage bins 41 opened around its circumference;

[0044] The central shaft 5 is fixed at the axis position of the driving assembly 2, and one end of the central shaft extends out of the driving assembly 2 and is fixed with the output end of the external motor;

[0045] A reset assembly 6 is fixed on a side of the drive assembly 2 that is close to each other;

[0046] Oscillating components 8 are arranged circumferentially on the central axis 5 and are close to the resetting components 6; and

[0047] The cleaning rod 7 is fixed to one end of the oscillating assembly 8 away from the central axis 5 .

[0048] In this embodiment, the driving assembly 2 includes:

[0049] A first fixed plate 21 is fixed to the inner wall of the sand washing tank 1;

[0050] The second fixed plate 22 is fixed to the side of the first fixed plate 21 away from the sand washing tank 1 by a connecting rod;

[0051] The outer gear 23 is rotatably disposed between the first fixed disk 21 and the second fixed disk 22, and the inner cylinder 3 is fixed on the side away from the first fixed disk 21;

[0052] an internal gear 24 rotatably disposed at the axis of the first fixed disk 21 and the second fixed disk 22 and fixed to the central shaft 5; and

[0053] There is at least one linkage gear 25 , which is rotatably disposed between the first fixed disk 21 and the second fixed disk 22 and meshes with the outer gear 23 and the inner gear 24 for transmission.

[0054] It should be noted that the inner gear 24 rotates as a driving wheel through the central shaft 5, and the outer gear 23 transmits the rotation of the inner gear 24 through the linkage gear 25. The linkage gear 25 is used to make the outer gear 23 and the inner gear 24 rotate in opposite directions, that is, the inner cylinder 3 and the cleaning rod 7 rotate in opposite directions, thereby improving the cleaning degree and generating relative stirring force in the sand washing tank 1.

[0055] As a preferred embodiment, the reset component 6 includes:

[0056] An oscillating plate 61 is fixed on the second fixed plate 22;

[0057] There are at least three reset frames 62, which are circumferentially fixed on the oscillation plate 61;

[0058] a sliding plate 64 slidably disposed in the reset frame 62; and

[0059] The return spring 65 is connected between the return frame 62 and the sliding plate 64 .

[0060] As a preferred embodiment, an arc-shaped guide surface 63 is provided at the connection position between the reset frame 62 and the oscillation disk 61 .

[0061] That is to say, by fixing the reset frame 62 on the oscillation disk 61 , a height difference can be formed on the inner wall of the oscillation disk 61 , thereby cooperating with the oscillation component 8 to generate intermittent oscillating force.

[0062] As a preferred embodiment, the oscillating component 8 includes:

[0063] There are at least three fixing rods 81, which are circumferentially fixed on the central axis 5 and have avoidance grooves 83 formed near the reset frame 62;

[0064] A base 82 is fixed inside the fixing rod 81;

[0065] an oscillation rod 84 slidably disposed within the fixed rod 81 and having an oscillation spring 86 disposed between the oscillation rod and the base 82; and

[0066] The rotating roller 85 is rotatably disposed on a side of the oscillating rod 84 close to the reset frame 62 .

[0067] As a preferred embodiment, a buffer pad 87 is fixed to the side of the oscillation rod 84 away from the oscillation spring 86 , and an anti-slip pad is fixed to the outer wall of the rotating roller 85 to facilitate its rotation on the inner wall of the oscillation disk 61 .

[0068] That is to say, when the rotating roller 85 rotates to the reset frame 62, due to the height difference between the reset frame 62 and the inner wall of the oscillation disk 61, the rotating roller 85 will quickly fall into the reset frame 62 through the oscillation rod 84 and the oscillation spring 86, thereby generating an oscillation force on the oscillation rod 84, thereby improving the degree of separation of sand and water, and avoiding the adhesion of the cleaned sand and gravel in the sand storage bin 41.

[0069] As a preferred embodiment, the elasticity of the reset spring 65 is greater than the elasticity of the oscillation spring 86 , so as to facilitate the reset of the oscillation rod 84 .

[0070] That is to say, when the rotating roller 85 falls into the reset frame 62, it will first press the sliding plate 64 to compress the reset spring 65. Then, because the elasticity of the reset spring 65 is greater than the elasticity of the oscillation spring 86, the sliding plate 64 will push the rotating roller 85, thereby causing it to detach from the reset frame 62 and enter the inner wall of the oscillation disk 61 again through rotation to rotate.

[0071] Specifically, first, water and sand and gravel to be cleaned are put into the feed port 12, and then the external motor is started to rotate the central shaft 5, and the oscillation component 8 and the bucket wheel 4 are rotated in the opposite direction through the driving component 2. During rotation, the water and sand in the sand washing pool 1 are stirred in the opposite direction, thereby enhancing the degree of mutual friction between the sand and gravel, thereby increasing the degree of destruction of the water vapor layer covering the surface of the sand and gravel, and improving the degree of sand washing. When the cleaning rod 7 rotates, the inner wall of the inner cylinder 3 can be cleaned to avoid clogging of the water filter holes on the inner cylinder 3. When the oscillation component 8 rotates, it can cause intermittent oscillation to the inner cylinder 3 by cooperating with the reset component 6, thereby increasing the degree of separation of the sand and gravel from water, and avoiding the adhesion of the cleaned sand and gravel to the sand storage bin 41.

[0072] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
