Description

Technical Field

[0001] The present invention relates to the technical field of well logging operations, and more particularly to a mobile sand drying platform. Background Art

[0002] During the exploration of oil and gas, the rock fragments broken by the drill bit at the bottom of the well are called rock cuttings. Rock cuttings are the most intuitive material for identifying the bottom oil, gas and lithology data during the drilling process. The rock cuttings are reflected from the bottom of the well to the wellhead through the sand-carrying capacity of the drilling fluid. The sampling personnel will collect, clean and store the rock cuttings on the sand drying platform so that the geologists can observe and record the original bottom data.

[0003] Sand drying is the process of washing sand samples and placing them on a sand drying table to air dry during the logging process. When the humidity reaches a certain requirement, they are bagged and stored.

[0004] After years of on-site operations, we have learned about the layout process and subsequent work procedures of the on-site sand drying platform. Due to environmental protection requirements, mud does not fall to the ground during the operation. Before each well operation, a traditional sand drying platform needs to be manually laid. The traditional sand drying platform is made of piled earth, with an area of ​​generally 13-18㎡ and a height of 20-25cm. It is laid in a "U" shape, with the main body of the sand drying platform inside and an anti-seepage membrane on the top to prevent seepage. The outer circle is a waterproof cofferdam.

[0005] Generally, soil platforms require the use of manual wheelbarrows to move soil, and generally about 0.3 cubic meters can be moved at a time. A sand drying platform requires about 5-6 cubic meters of soil to be built. The physical labor is intensive. In seasons with high temperatures, the time and intensity of outdoor work are increased, which can easily lead to health problems such as heat stroke and dehydration. In winter, outdoor work is severely frozen, making it difficult to obtain soil, which increases labor time and intensity.

[0006] When workers lay out or collect sand samples for a long time, they may experience orthostatic hypotension after standing up, which may cause symptoms such as dizziness, blurred vision, and fainting. Sampling personnel often have to squat on the sand drying platform to place sand samples, and geologists also have to squat on the sand drying platform to describe the sand samples. This action can cause varying degrees of damage to the lumbar and cervical vertebrae, which is not good for occupational health.

[0007] Moreover, for offshore operations, some platforms have fast drilling speeds and many types and quantities of sand samples. When the oven is running at full capacity, there is insufficient storage space for the sand samples to be baked, and the natural drying samples dry slowly. Summary of the invention

[0008] The present invention designs and develops a mobile sand drying platform, which realizes the effects of being movable, foldable and easy to store by combining supporting legs and a platform, and increases air permeability through a screen to improve the drying speed.

[0009] The technical solution provided by the present invention is:

[0010] A mobile sand drying platform, comprising:

[0011] The first countertop; and

[0012] A second table top, which is foldably connected to the first table top in a symmetrical manner;

[0013] A plurality of support legs, which are equally spaced and detachably disposed at the bottom of the first table top and the second table top;

[0014] At least one screen is detachably arranged on the first table top and / or the second table top.

[0015] Preferably, the first table top and the second table top are both frame structures, and the structures of the first table top and the second table top are completely the same.

[0016] Preferably, the plurality of supporting legs each include:

[0017] An upper leg, one end of which is fixedly arranged at a vertex angle of the first table top or the second table top away from each other, and the upper leg is perpendicular to the first table top and the second table top;

[0018] A double-headed column, one end of which is detachably connected to the other end of the upper leg;

[0019] a base plate including a face end and a rod end connected vertically;

[0020] The rod end and the other end of the double-headed column are detachably connected to each other, and the face end is arranged on the ground.

[0021] Preferably, it also includes:

[0022] Two hinges are spaced apart and arranged between the first table top and the second table top.

[0023] Preferably, it also includes:

[0024] The middle reinforcing plate is arranged on the first table surface and the second table surface close to the two hinges.

[0025] Preferably, it also includes:

[0026] A reinforcing angle plate is arranged at a top corner of the first table top and the second table top on a side away from each other.

[0027] Preferably, the at least one screen is selectively snap-fitted into the first deck and / or the second deck.

[0028] Preferably, the sizes of the first table top and the second table top are both 1200mm*1200mm.

[0041] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0042] like Figure 1 As shown, the present invention provides a mobile sand drying platform, comprising:

[0043] A first table top 110, a second table top 120 and a plurality of supporting legs.

[0044] The first table top 110 and the second table top 120 are symmetrically arranged and are foldably connected to each other; the plurality of supporting legs are equally spaced and detachably arranged at the bottom of the first table top 110 and the second table top 120 .

[0045] The first table top 110 and the second table top 120 are both frame structures, and in this embodiment, the structures of the first table top 110 and the second table top 120 are completely the same.

[0046] In this embodiment, the folding function is achieved between the first table top 110 and the second table top 120 by two hinges 130, and the two hinges 130 are arranged at an interval. In order to ensure stability, the two hinges 130 are arranged near the borders of the first table top 110 and the second table top 120.

[0047] The supporting leg includes an upper leg 141, a double-headed column 142 and a base plate 143. One end of the upper leg 141 is fixedly arranged at the top corner of the first table top 110 or the second table top 120 away from each other, and the upper leg 141 is perpendicular to the first table top 110 and the second table top 120; one end of the double-headed column 142 is detachably connected to the other end of the upper leg 141; the base plate 143 includes a vertically connected face end and a rod end; the rod end is detachably connected to the other end of the double-headed column 142, and the face end is arranged on the ground.

[0048] In this embodiment, the stud column 142 is threadedly connected to the upper leg 141 and the bottom plate 143 .

[0049] like Figure 2 , Figure 3 As shown, the sizes of the first table top 110 and the second table top 120 are both 1200 mm*1200 mm.

[0050] In this embodiment, the screen replaced by the well team (not shown in the figure) is laid on the first table 110 and / or the second table 120. The size of the screen is 600mm*1200mm. In order to ensure the sand drying efficiency, up to 4 screens can be used to be clamped in the first table 110 and the second table 120.

[0051] like Figure 4 , Figure 5 As shown, it is a schematic diagram of the dimensions of the upper leg 141, such as Figure 6 , Figure 7It is a schematic diagram of the dimensions of the double-ended column 142, and the length of the double-ended column 142 is 600mm, 700mm or 800mm. The height of the sand drying platform can be adjusted by the length of the double-ended column 142. The height of the sand drying platform can be adjusted to 95cm-115cm, which effectively changes the working posture of the operator.

[0052] In this embodiment, the surface end of the bottom plate 143 is a 300mm*300mm*5mm steel plate base counterweight.

[0053] like Figure 8 As shown, a middle reinforcing plate 151 is provided at the first table 110 and the second table 120 close to the two hinges 130; and a reinforcing angle plate 161 is provided at the top corners of the first table 110 and the second table 120 away from each other to enhance stability.

[0054] In this embodiment, the first table top 110 and the second table top 120 are folded in the direction of the upper legs 141, so the two hinges 130 are arranged at the bottom of the first table top 110 and the second table top 120, that is, the two hinges 130 are arranged on the middle reinforcing plate 151 between the first table top 110 and the second table top 120.

[0055] The mobile sand drying platform provided by the present invention can be put into use after it is assembled. The assembly difficulty is about 20 minutes (single platform) for two people. The water mixed in the sand sample can flow out from the screen to the bottom, increasing the air permeability, thereby accelerating the drying speed. An anti-seepage membrane is laid below according to environmental protection requirements to prevent the sand sample water from dripping and seeping into the ground. Solid wooden blocks are used around the anti-seepage membrane or soil is taken nearby to build a cofferdam, thereby strengthening environmental protection, reducing the intensity and time of physical labor, and simplifying the on-site operation process. Moreover, during use, it can effectively resist the adverse weather such as strong winds and heavy rains on the collection of geological data. Impact; After the operation is completed, this sand drying table is simple, easy to disassemble and foldable. After disassembly, it can be directly stored in the geological room or trunk for next use; Some well platforms have small working space, and the instrument room needs to be moved after dragging the derrick. It may be necessary to move the sand drying table. This operation is much simpler after using the mobile sand drying table; in terms of occupational health, it reduces the frequency of squatting and thus reduces the frequency of orthostatic hypotension, thereby ensuring occupational health. Geological personnel can maintain an upright posture when laying sand samples, reducing the disappearance of physiological curvature of the lumbar spine, cervical spine and peripheral nerve muscles due to long-term bending.

[0056] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
