Description

Technical Field

[0001] This utility model belongs to the technical field of display cabinets and relates to a drilling cuttings storage and display device. Background Technology

[0002] Drilling cuttings are fine rock particles and fragments formed when the drill bit breaks rocks during oil and gas drilling operations. They are carried to the surface from the bottom of the well by circulating media such as drilling fluid. During the drilling process, drilling cuttings are usually collected every meter. By analyzing the characteristics of drilling cuttings, such as color, shape, size, and mineral composition, the rock type of the strata encountered can be determined, such as sandstone, mudstone, and limestone, and thus the lithological distribution of the underground strata can be understood.

[0003] Currently, after drilling cuttings are collected, they are usually simply packaged in resealable bags, labeled, and stored in a warehouse. However, this method of storage makes it difficult to see which part of the wellbore the drilling cuttings were collected from, which is not conducive to the later analysis of the downhole rock formations.

[0004] Chinese utility model patent CN218259227U, with an application date of August 22, 2022 and an authorization announcement date of January 10, 2023, provides a rock cuttings collection box. The device includes a storage box with six drawers inside. Each drawer has a handle fixedly connected to its front and a divider fixedly connected to its inner wall. Both sides of the drawers have snap-fit ​​components, and both sides of the storage box have locking components. Each side of the storage box has a slot. The snap-fit ​​components include a connecting block and a retaining ring. One side of the connecting block is fixedly connected to one side of the drawer, and the connecting block and retaining ring are rotatably connected via a pin. The locking components include a movable block and a spring. The surface of the movable block slides in connection with the inside of the slot, and the surface of the movable block contacts the surface of the retaining ring. This device can collect rock cuttings, but it makes it difficult to visually identify which part of the wellbore the drilling cuttings were collected from, which is detrimental to subsequent analysis of the downhole rock formations.

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] This utility model relates to a drilling cuttings collection and display device, such as... Figure 1 As shown, the system includes a first cuttings storage cabinet 101, a first mounting groove 103 on the side wall of the first cuttings storage cabinet 101, a wellbore section model 201 with a matching shape installed in the first mounting groove 103, a combined cuttings storage cabinet 102 installed on the end face of the first cuttings storage cabinet 101, and a second mounting groove 104 coaxial with the first mounting groove 103 on the side wall of the combined cuttings storage cabinet 102, a wellbore section model 202 with a matching shape installed in the second mounting groove 104, such as... Figure 2 As shown, the end face of the second section model 202 of the wellbore, near the first cuttings storage cabinet 101, is fixed to the end face of the first section model 201 of the wellbore. Both the first cuttings storage cabinet 101 and the combined cuttings storage cabinet 102 are made of transparent material. Both the first section model 201 and the second section model 202 of the wellbore are printed using conventional 3D materials and are integrally formed.

[0027] like Figure 3 As shown, the height of the first section model 201 of the wellbore is the same as the height of the first cuttings storage cabinet 101, and the height of the combined cuttings storage cabinet 102 is the same as the height of the second section model 202 of the wellbore. The combined cuttings storage cabinet 102 includes a second cuttings storage cabinet 1021 that is detachably connected to the first cuttings storage cabinet 101. Several third cuttings storage cabinets 1022 are detachably connected in sequence to the end face of the second cuttings storage cabinet 1021 away from the first cuttings storage cabinet 101.

[0028] The cross-section of the third rock cuttings storage cabinet 1022 is the same as that of the second rock cuttings storage cabinet 1021, and the height of the third rock cuttings storage cabinet 1022 is 0.5m.

[0029] The top plates and side walls of the first rock cuttings storage cabinet 101, the second rock cuttings storage cabinet 1021, and the third rock cuttings storage cabinet 1022 are detachably connected.

[0030] like Figure 4 As shown, a first clamp 105 is installed on the first cuttings storage cabinet 101, and the first section model 201 of the well body is detachably connected to the first cuttings storage cabinet 101 through the first clamp 105. A second clamp 106 is installed on the combined cuttings storage cabinet 102, and the second section model 202 of the well body is detachably connected to the combined cuttings storage cabinet 102 through the second clamp 106.

[0031] Both the first rock cuttings storage cabinet 101 and the combined rock cuttings storage cabinet 102 have a scale mark 4 on the side, with a dimensional accuracy of 0.01m.

[0032] like Figure 6 As shown, a base 3 is installed on the end face of the well body two-section model 202 away from the well body one-section model 201. The base 3 includes a connecting seat 302. One side of the connecting seat is fixedly connected to the well body two-section model 202. The side of the connecting seat 302 away from the well body two-section model 202 is fixedly connected to one end of the rotating shaft 301. The other end of the rotating shaft 301 is rotatably connected to a rotating seat 303.

[0033] like Figure 7 As shown, a fixed base 304 is fixedly connected to the side of the rotating seat 303 away from the rotating shaft 301, and the end of the rotating shaft 301 near the rotating seat 303 is rotatably connected to the fixed base 304.

[0034] Example 1

[0035] The drilling cuttings collection and display device includes a first cuttings storage cabinet 101. The side wall of the first cuttings storage cabinet 101 is provided with a first mounting groove 103. A wellbore section model 201 with a matching shape is installed in the first mounting groove 103. A combined cuttings storage cabinet 102 is installed on the end face of the first cuttings storage cabinet 101. The side wall of the combined cuttings storage cabinet 102 is provided with a second mounting groove 104 coaxial with the first mounting groove 103. A wellbore section model 202 with a matching shape is installed in the second mounting groove 104. The end face of the wellbore section model 202 near the first cuttings storage cabinet 101 is fixed to the end face of the wellbore section model 201. Both the first cuttings storage cabinet 101 and the combined cuttings storage cabinet 102 are made of transparent material. During use, the well cuttings are compared with the wellbore model, and the first cuttings storage cabinet 101 and the combined cuttings storage cabinet 102 are filled according to the collection locations within the wellbore. By comparing the cuttings in the first cuttings storage cabinet 101 with the wellbore first section model 201, and comparing the combined cuttings storage cabinet 102 with the wellbore second section model 202, the drilling cuttings collection locations can be clearly seen, the distribution of underground rock strata can be clearly identified, and the distribution of rock strata can be clearly seen. The distribution of rock strata can be directly compared and divided based on lithology, fossils and other characteristics, and a regional stratigraphic framework can be established, providing a basis for further research on geological laws. In addition, during resource extraction, the distribution of rock strata can be clearly seen, which helps to rationally plan the extraction scheme, reduce the uncertainty in the extraction process, reduce extraction costs, improve resource recovery rate, and ensure the safety of the extraction process.

[0036] Example 2

[0037] Based on Embodiment 1, the height of the first section model 201 of the wellbore is the same as the height of the first cuttings storage cabinet 101, and the height of the combined cuttings storage cabinet 102 is the same as the height of the second section model 202 of the wellbore. The combined cuttings storage cabinet 102 includes a second cuttings storage cabinet 1021 detachably connected to the first cuttings storage cabinet 101. Several third cuttings storage cabinets 1022 are detachably connected sequentially to the end face of the second cuttings storage cabinet 1021 away from the first cuttings storage cabinet 101. Setting the combined cuttings storage cabinet 102 in the form of multiple stacked cuttings storage cabinets has two advantages: firstly, it can evenly transfer the load, as multiple stacked cuttings storage cabinets can distribute the load generated by the internal cuttings to the lower cuttings storage cabinets layer by layer; secondly, if a single load-bearing unit has material defects or uneven stress, it is easy to cause local damage, while the stacking of multiple cuttings storage cabinets, through the coordinated stress of multiple components, disperses the risk and ultimately avoids excessive local pressure that could lead to deformation or breakage of the cuttings storage device. Secondly, by increasing or decreasing the number of stacked cuttings storage cabinets or changing the specifications of the cuttings storage cabinets, the height of the combined cuttings storage cabinet 102 can be adjusted to adapt to wellbore second-section models 202 of different heights, thus meeting different design requirements.

[0038] Example 3

[0039] Based on Embodiment 2, the cross-section of the third cuttings storage cabinet 1022 of this device is the same as that of the second cuttings storage cabinet 1021, and the height of the third cuttings storage cabinet 1022 is 0.5m. Making the third cuttings storage cabinet 1022 of the same shape has two advantages: first, it facilitates manufacturing, allowing the use of the same set of molds during production. A unified mold can better control the dimensional accuracy and quality stability of components, reducing quality fluctuations caused by shape differences and improving product consistency and reliability; second, it reduces the number of molds to be designed and manufactured, effectively lowering mold design costs and reducing capital consumption. Furthermore, the identical shape of the third cuttings storage cabinet 1022 allows for large-scale production, which is beneficial for improving production efficiency.

[0040] Example 4

[0041] Based on Embodiment 3, the top plates and side walls of the first cuttings storage cabinet 101, the second cuttings storage cabinet 1021, and the third cuttings storage cabinet 1022 of this device are detachably connected. For example... Figure 5 As shown, the first rock cuttings storage cabinet 101, the second rock cuttings storage cabinet 1021, and the third rock cuttings storage cabinet 1022 are detachably connected to each other using straight-arm buckles. The top and side walls of the first, second, and third rock cuttings storage cabinets 101, 1021, and 1022 are detachably connected, allowing for easy opening of the top panels to store and sample the rock cuttings inside. The straight-arm latches provide strong connection force, tightly securing the cabinets together and preventing separation during use, ensuring safe storage and transportation. Furthermore, simply aligning the latches with the corresponding positions allows for quick connection and separation without tools, facilitating flexible combination or disassembly according to actual needs.

[0042] Example 5

[0043] Based on Embodiment 4, the first cuttings storage cabinet 101 of this device is equipped with a first clamp 105. The first section model 201 of the wellbore is detachably connected to the first cuttings storage cabinet 101 via the first clamp 105. The combined cuttings storage cabinet 102 is equipped with a second clamp 106. The second section model 202 of the wellbore is detachably connected to the combined cuttings storage cabinet 102 via the second clamp 106. The clamp connection offers several advantages: firstly, it facilitates installation, as the clamp installation process is relatively simple and requires no special tools or complex operating skills, greatly saving installation time and labor costs; secondly, it protects the surface of components, as the clamp is made of a material with a certain degree of elasticity, preventing excessive damage or wear to the surface of components during connection; and thirdly, it provides good stability, as the clamp, once tightened, forms a stable ring constraint that can resist dynamic loads such as vibration and impact, ensuring the safety and stability of the connection.

[0044] Example 6

[0045] Based on Embodiment 5, both the first cuttings storage cabinet 101 and the combined cuttings storage cabinet 102 of this device are marked with scale 4 on their sides, with a dimensional accuracy of 0.01m. Scale 4 can provide an accurate measurement standard for the wellbore structural model, serving as a spatial positioning reference system to help researchers accurately describe and locate the positions of various geological bodies or phenomena on the wellbore structural model, facilitating researchers to accurately measure various geological elements on the model.

[0046] Example 7

[0047] Based on Embodiment Six, a base 3 is installed on the end face of the wellbore two-section model 202 away from the wellbore one-section model 201. The base 3 includes a connecting seat 302, one side of which is fixedly connected to the wellbore two-section model 202, and the side of the connecting seat 302 away from the wellbore two-section model 202 is fixedly connected to one end of a rotating shaft 301. The other end of the rotating shaft 301 is rotatably connected to a rotating seat 303. Since the geological structure downhole is usually quite complex, allowing the wellbore structure model and the cuttings storage container to rotate around the axis serves two purposes: first, it allows researchers to intuitively perceive the spatial positional comparison between the wellbore structure model 2 and different rock masses and strata in terms of vertical, front-back, and horizontal relationships, thus improving the research effect; second, within the limited display space, the display direction of the model can be flexibly adjusted through the rotating shaft, so that it can be clearly observed from different angles without having to set up a separate display position for each observation angle, thereby saving space.

[0048] Example 8

[0049] Based on Embodiment 7, a fixed base 304 is fixedly connected to the side of the rotating seat 303 away from the rotating shaft 301, and the end of the rotating shaft 301 near the rotating seat 303 is rotatably connected to the fixed base 304. Since the rock cuttings storage container is relatively heavy, it is prone to tipping over and causing personal injury during actual use. To reduce the risk of tipping, a fixed base 304 is fixedly connected to the side of the rotating seat 303 away from the rotating shaft 301, and the end of the rotating shaft 301 near the rotating seat 303 is inserted into and rotatably connected to the fixed base 304. By adding a fixed base, firstly, the center of gravity of the device can be lowered, providing a wider and more stable support foundation for the cuttings storage container and the wellbore structure model, reducing the possibility of the model shaking or tipping over during rotation, and also preventing the model components from loosening or being damaged due to vibration caused by rotation; secondly, since the cuttings storage container itself is quite heavy when filled with cuttings, and the fixed base has a large contact area, it can evenly distribute the weight of the cuttings storage container and the wellbore structure model onto the support surface, avoiding damage to the pressure surface due to excessive local pressure.
