Description

Technical Field

[0001] This utility model belongs to the field of well logging coring testing technology, specifically relating to a simulated coring device. Background Technology

[0002] Oil well logging coring equipment is a specialized device used to obtain rock samples from underground oil reservoirs. It is crucial for understanding reservoir characteristics, assessing oil and gas reserves, and developing extraction plans. With technological advancements, modern oil well logging coring equipment has not only improved coring efficiency and quality but also integrated more sensors and technologies, such as real-time data transmission and high-resolution imaging, to provide more detailed subsurface information.

[0003] Oil well logging simulation coring is a process that simulates the actual coring process in a laboratory or training environment. The coring device in related technologies typically includes a support frame and a rock frame. The coring equipment is used to fix itself to the support frame, and the rock frame is used to hold the rock. The coring equipment is then drilled toward the rock on the rock frame to perform the coring test.

[0004] However, the simulated coring devices in related technologies have the following drawbacks:

[0005] (1) When installing and adjusting the coring equipment, it is necessary to spread out the push arm and fix the push arm to the support frame. This is not only complicated to operate, but also poses a major safety risk of personnel's hands being squeezed.

[0006] (2) The continuous simulated coring process requires multiple disassembly and assembly of the simulated coring device, resulting in low testing efficiency and a heavy workload for staff.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other.

[0036] like Figure 1-4 The present invention is illustrated in an embodiment of the present invention, which discloses a simulated coring device, including a support base 1, a rock frame 2 for installing rocks on the support base 1, and a limiting plate 3 located above the rock frame 2 on the support base 1. The limiting plate 3 is arc-shaped with its open side facing upward, and the inner arc of the limiting plate 3 is the same as the outer arc of the coring device, so that the coring device can be tightly fitted with the limiting plate 3 to form a limiting position.

[0037] In one embodiment, such as Figure 1 , Figure 2 As shown, locking plates 4 are hinged to both sides of the top of the limiting plate 3. The two locking plates 4 are respectively connected to the limiting plate 3 by locking buckles 5, and each of the two locking plates 4 is provided with a limiting block 6 that can be locked and engaged with the core extraction device to fix the core extraction device. At the same time, a rotating handle 7 is fixedly connected to each of the two locking plates 4 to facilitate the operator to pull the locking plate 4 and quickly rotate it.

[0038] In one embodiment, such as Figure 1 , Figure 2 As shown, a core-taking hole 8 is provided through the middle of the limiting plate 3. When the core-taking equipment is fixed, the drill bit of the core-taking equipment can pass through the core-taking hole 8 and drill towards the rock on the rock frame 2, thereby simulating the core-taking operation.

[0039] The simulated coring device in this embodiment makes the assembly and disassembly of the coring equipment quicker and more convenient. The coring equipment does not need to be installed and adjusted without the need to spread the push arm, which simplifies the operation steps, reduces the major safety risk of personnel's hands being squeezed, and improves work efficiency.

[0040] In this embodiment, the locking buckle 5 adopts a snap-on structure to achieve quick fixation of the locking plate 4. The size and shape of the limiting block 6 are designed according to the outer diameter of the coring instrument and the characteristics of its mechanical structure, which not only meets the strength requirements but also ensures a firm fit with the outer diameter of the instrument after installation, thereby improving the limiting effect of the coring instrument. The rotating handle is based on the principles of hand mechanics, which facilitates lifting and allows for precise control and positioning during installation.

[0041] In one embodiment, such as Figure 1 , Figure 2 As shown, the support base 1 includes a horizontally arranged support base plate 101 and two vertically arranged parallel support side plates 102. The bottoms of the two support side plates 102 are connected to the support base plate 101 by fastening bolts 103, and the tops are connected to the limiting plate 3 by fastening bolts 103. At the same time, a pull-out hole 104 is formed between the limiting plate 3, the support base plate 101, and the two support side plates 102. The rock frame 2 is horizontally slidably connected in the pull-out hole 104 so that the position of the rock can be adjusted and it can be quickly replaced.

[0042] In one embodiment, such as Figure 2 , Figure 3 As shown, each of the two supporting side plates 102 is provided with a plurality of limiting holes 9. The plurality of limiting holes 9 on each supporting side plate 102 are arranged at equal intervals along the sliding direction of the rock frame 2. A limiting pin 10 is slidably inserted into at least one limiting hole 9. A plurality of locking holes 11 are provided on both sides of the rock frame 2. The plurality of locking holes 11 are provided one-to-one with the plurality of limiting holes 9, and the limiting pin 10 can pass through the corresponding locking hole 11, thereby realizing the limiting of the rock frame 2.

[0043] In this embodiment, the limiting pin 10 adopts a press-type elastic unlocking method, that is, the front part of the limiting pin 10 has a spring ball locking structure, and the unlocking can only be achieved by pressing the spring ball, so as to ensure the limiting effect of the rock frame 2.

[0044] In one embodiment, such as Figure 1 , Figure 3 As shown, the rock rack 2 includes a rectangular rock box 201 with an opening at the top, and rocks can be placed inside the rock box 201. A receiving plate 202 is horizontally arranged below the rock box 201. The rock box 201 and the receiving plate 202 are integrally connected by two vertically and parallelly arranged connecting plates 203, and locking holes 11 are correspondingly arranged on the connecting plates 203.

[0045] In one embodiment, such as Figure 3 , Figure 4 As shown, the bottom of the rock box 201 and the receiving plate 202 are respectively provided with first chip removal holes 12, and the two first chip removal holes 12 are aligned. Second chip removal holes 13 are provided on both sides of the rock box 201, and third chip removal holes 14 are provided on the two supporting side plates 102, with the two second chip removal holes 13 corresponding to the corresponding third chip removal holes 14. By providing the first chip removal holes 12, second chip removal holes 13, and third chip removal holes 14, it is ensured that rock cuttings can be smoothly discharged with the flowing water during the simulated core sampling process, while also achieving a lightweight design.

[0046] In one embodiment, such as Figure 3 , Figure 4 As shown, a tightening screw 15 is threadedly connected to one side of the rock box 201. A control handle 16 is fixedly connected to one end of the tightening screw 15, and a retaining plate 17 is fixedly connected to the other end. The retaining plate 17 is used to tighten and limit the rock, thereby fixing the rock. This design allows the rock box 201 to adapt to rocks of different sizes and shapes, effectively improving its adaptability.

[0047] In one embodiment, such as Figure 3 , Figure 4As shown, the rock box 201 is provided with a weight reduction hole 18 on the side away from the top tightening screw 15 to achieve a lightweight design of the rock box 201, which facilitates the handling and operation of the simulated coring device by the staff.

[0048] As shown above, this simulated coring device enables rapid and safe assembly and disassembly of the coring equipment, making operation simpler and faster, and reducing safety risks. Simultaneously, the rock can be quickly replaced, effectively improving testing efficiency and reducing the workload of staff.
