Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, specifically a sandstone reservoir detection device. Background Technology

[0002] The storage capacity of sandstone reservoirs is determined by the rock physical properties of the reservoir, typically including its porosity and permeability. Porosity determines the size of the reservoir's storage capacity, while permeability determines the seepage capacity of the reservoir. There is a large demand for sandstone reservoir detection equipment in China. The main methods for sandstone reservoir detection include seismic exploration technology, electrical exploration technology, geomagnetic exploration technology, seismic detection methods for thin interbedded sandstone reservoirs, and physical modeling technology, among which high-density electrical resistivity tomography (EDT) is the main electrical exploration technology.

[0003] When using a high-density electrical resistivity tomography (EDT) device, a dozen or so electrode rods need to be inserted into different matrix points. However, during the insertion and power-on process, the electrode plugs can easily detach from the detection device due to loosening of the electrode plugs or pulling of the signal lines, rendering the electrode rods unusable. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a sandstone reservoir detection device to solve the problem that the electrode plugs of existing high-density electrical resistivity tomography (EDT) devices are prone to detaching from the detection equipment, resulting in the electrode rods being unusable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sandstone reservoir detection device, comprising a housing, wherein a sandstone reservoir detection device is disposed within the housing, and the detection device is provided with a connector slot, a fixing slot, and a control knob, wherein a fastening frame is disposed above the detection device, and the fastening frame is provided with a limiting slot corresponding to the connector slot and a fixing hole corresponding to the fixing slot, wherein a limiting hole is provided at the top of the limiting slot, and an operating port corresponding to the control knob is provided on the fastening frame; an electrode plug is inserted into the connector slot, and a third limiting block corresponding to the limiting slot is disposed on the electrode plug; fastening components for pressing the fastening frame downward are movably installed on the fixing slot and the fixing hole.

[0006] Preferably, the top of the housing is provided with a flip-up movable cover, which forms the fastening frame.

[0007] Preferably, the fastening assembly includes a fastening bolt that passes through the fixing hole, the bottom end of the fastening bolt being threaded into the fixing groove, the top end of the fastening bolt being provided with a second limiting block, and a fastening spring being sleeved on the outside of the fastening bolt, with the fastening spring located between the second limiting block and the fastening frame.

[0008] In a preferred embodiment, the top of the second limiting block is provided with a butterfly-shaped piece for twisting. In use, the second limiting block is twisted by the butterfly-shaped piece to overcome the elastic force of the fastening spring, so that the fastening bolt is screwed into the fixing groove. The elastic force of the fastening spring pushes the fastening frame downward, and the limiting groove squeezes the electrode plug downward, so that the electrode plug is firmly connected with the insertion groove, avoiding the electrode plug from falling out of the insertion groove or poor contact between the two.

[0009] Preferably, the bottom of the housing is provided with a mounting cavity with an opening on one side, and a wind power converter is slidably installed in the mounting cavity; the inner end of the wind power converter is provided with a connecting line connected to the detection device, and the outer end of the wind power converter is movably connected to a telescopic rod through a connecting rod, and a wind power generation device is installed at the end of the telescopic rod.

[0010] Preferably, the wind power converter is provided with directional pulleys on its upper and lower sides, which fit tightly against the upper and lower inner walls of the mounting cavity. In a preferred embodiment, the inner wall of the mounting cavity is provided with protrusions to limit and fix the wind power converter, preventing it from detaching from the mounting cavity. The directional pulleys allow the wind power converter to move within the mounting cavity, facilitating the removal or placement of the wind power generation device. Connecting cables ensure the wind power converter remains energized during movement.

[0011] Preferably, the bottom of the housing is provided with a support frame, the edges of which slope from top to bottom and from the inside out. Retractable support legs are mounted at the four inner corners of the support frame via movable shafts. This configuration allows the housing to be supported when the support legs are retracted into the support frame. When the support legs rotate out of the support frame via the movable shafts, the inclined inner wall of the support frame causes the support legs to tilt outwards. The inclined support frame then limits and fixes the support legs, preventing them from folding and becoming unbalanced due to stress.

[0012] Preferably, the support leg includes an outer cylinder and an inner rod. The top of the outer cylinder is movably connected to the inner wall of the support frame via a movable shaft. The outer surface of the inner rod is provided with mating threads to the inner surface of the outer cylinder, and the bottom of the inner rod is equipped with a rotatable and tiltable support plate via a movable shaft.

[0013] Preferably, the connecting rod and the telescopic rod are movably connected via a pivot, and a fixing rod for limiting and fixing is bolted between the connecting rod and the telescopic rod. This arrangement allows the telescopic rod to rotate to a vertical position via the pivot, and the fixing rod secures the connecting rod and the telescopic rod, thereby erecting the wind power generation device and facilitating its power generation.

[0014] Preferably, the fastening frame has an operating port corresponding to the control knob, which facilitates the operation and control of the control knob on the detection device.

[0015] Preferably, the inner side of the movable cover is provided with multiple mesh bags, which facilitates the holding of electrode rods and signal lines.

[0016] This utility model provides a sandstone reservoir detection device, which has the following beneficial effects:

[0017] This invention, through the cooperation of fastening components and fastening brackets, can limit and fix the electrode plug of the electrode rod in the insertion slot, preventing the electrode plug from falling out of the insertion slot or causing poor contact due to loosening or pulling of the signal line, thus ensuring the normal use of the electrode rod.

Fastening components 13 for pressing the fastening frame 12 downward are movably installed on the fixing groove 17 and the fixing hole 1203.

[0027] Among them, the detection device 2 can be an existing high-density electrical resistivity tomography (ERT) detection device, the electrode plug 19 can be the electrode rod of the high-density ERT detection device, the number of electrode plugs 19 is multiple, and correspondingly, the number of insertion slots 16 used to insert the electrode plugs 19 is also multiple, and they can be distributed in an array.

[0028] In this embodiment of the present invention, a fastening frame 12 is provided above the detection device 2. The fastening frame 12 is provided with a limiting groove 1204 corresponding to the insertion groove 16 and a fixing hole 1203 corresponding to the fixing groove 17. A limiting hole 1202 is provided at the top of the limiting groove 1204. An operation port 1201 corresponding to the control knob 18 is provided on the fastening frame 12.

[0029] In some embodiments, the top of the housing 1 is provided with a flip-up movable cover 15, which forms the fastening frame 12. Specifically, the movable cover 15 has a limiting groove 1204 corresponding to the insertion slot 16 and a fixing hole 1203 corresponding to the fixing slot 17. The limiting groove 1204 has a limiting hole 1202 at its top, and the movable cover 15 has an operating port 1201 corresponding to the control knob 18. When used as a cover, the movable cover 15 can also be used to limit the position of the electrode plug 19 inserted into the insertion slot 16.

[0030] In some embodiments, the fastening assembly 13 includes a fastening bolt 1301 that passes through the fixing hole 1203. The bottom end of the fastening bolt 1301 is threaded into the fixing groove 17. The top end of the fastening bolt 1301 is provided with a second limiting block 1304, which is located above the fastening frame 12. A fastening spring 1303 is sleeved on the outside of the fastening bolt 1301, and the fastening spring 1303 is located between the second limiting block 1304 and the fastening frame 12. In a preferred embodiment, the top of the second limiting block 1304 is provided with a butterfly-shaped piece for twisting. In use, the second limiting block 1304 is twisted by the butterfly-shaped piece to overcome the elastic force of the fastening spring 1303, so that the bottom end of the fastening bolt 1301 is screwed into the fixing groove 17. The elastic force of the fastening spring 1303 is used to press the fastening frame 12 downward, and the limiting groove 1204 is used to press the electrode plug 19 downward, so that the electrode plug 19 is firmly connected with the insertion groove 16, preventing the electrode plug 19 from falling out of the insertion groove 16 or poor contact between the two.

[0031] In some embodiments, the fastening bolt 1301 is provided with a first limiting block 1302, and the first limiting block 1302 and the second limiting block 1304 are located below and above the fastening frame 12, respectively.

[0033] In some embodiments, the wind power converter 4 is provided with directional pulleys on its upper and lower sides that fit tightly against the upper and lower inner walls of the mounting cavity 3. By providing directional pulleys, the wind power converter 4 can move within the mounting cavity 3, thereby facilitating the removal or placement of the wind power generation device 11 from or into the mounting cavity 3. The connection line 5 ensures that the wind power converter 4 remains energized during movement.

[0034] In some embodiments, a support frame 6 is provided at the bottom of the housing 1. The edges of the support frame 6 slope from top to bottom and from the inside to the outside. Retractable support legs 7 are mounted on the four inner corners of the support frame 6 via movable shafts. This configuration allows the housing 1 to be supported when the support legs 7 are retracted into the support frame 6. When the support legs 7 are rotated out of the support frame 6 via the movable shafts, the support legs 7 tilt outwards because the inner wall of the support frame 6 is inclined. The inclined support frame 6 then limits and fixes the support legs 7, preventing them from folding and becoming unbalanced due to stress.

[0035] In some embodiments, the support leg 7 includes an outer cylinder and an inner rod.

[0036] In some embodiments, the connecting rod 8 and the telescopic rod 9 are movably connected by a pivot, and a fixing rod 10 for limiting and fixing is bolted between the connecting rod 8 and the telescopic rod 9. This configuration allows the telescopic rod 9 to rotate to a vertical position via the pivot, and the fixing rod 10 secures the connecting rod 8 and the telescopic rod 9, thereby enabling the wind power generation device 11 to be erected and facilitating power generation.

[0037] In some embodiments, the fastening frame 12 is provided with an operation port 1201 corresponding to the control knob 18, and the operation port 1201 facilitates the operation and control of the control knob 18 on the detection device 2.

[0038] In some embodiments, the inner side of the movable cover 15 is provided with a plurality of mesh bags 14, which facilitate the holding of electrode rods and signal lines.

[0039] Working principle:

[0040] In practical use, depending on actual needs, choose whether to open the support leg 7 for support. Insert the electrode plug 19 of the electrode rod into the insertion slot 16, and ensure that the electrode rod, along with the signal wire on the electrode rod, passes through the limiting hole 1202 from the limiting slot 1204. Align the fastening bracket 12 with the detection device 2, and align the limiting slot 1204 and the fastening bolt 1301 with the insertion slot 16 and the fixing slot 17, respectively. Through the cooperation between the limiting slot 1204 and the third limiting block 1901, the electrode plug 19 is limited and fixed. The butterfly plate rotates the second limiting block 1304 to overcome the elastic force of the fastening spring 1303, causing the bottom end of the fastening bolt 1301 to be screwed into the fixing groove 17. The elastic force of the fastening spring 1303 is used to press the fastening frame 12 downward, and the limiting groove 1204 is used to press the electrode plug 19 downward, so that the electrode plug 19 is firmly connected to the insertion groove 16, preventing the electrode plug 19 from falling out of the insertion groove 16 or poor contact between the two. The electrode rod is then inserted into the pre-set matrix detection point and detected by the detection device 2.
