Description

Technical Field

[0001] The utility model relates to the technical field of rock formation data acquisition equipment, in particular to a data analysis device for tight sandstone reservoirs. Background Art

[0002] Tight sandstone reservoir is a special type of reservoir, which is mainly composed of sandstone with relatively low porosity and permeability. With the gradual reduction of conventional oil and gas resources, the development of oil and gas resources in tight sandstone reservoirs has become increasingly important. Its resource potential is huge. Through fracturing and other production-increasing measures, a complex fracture network can be formed in the tight sandstone reservoir, improving the seepage capacity of oil and gas, thereby achieving economical and efficient exploitation.

[0003] Before mining, microseismic monitoring is needed to detect the geological conditions of tight sandstone reservoirs. In order to ensure the accuracy and efficiency of the detection results, microseismic fluctuations need to be detected simultaneously on the ground and underground. Underground detection requires opening a horizontal pipeline under the rock layer and then placing the equipment in the pipeline. The existing method is to use a probe rod to push the equipment into the pipeline. This method makes the layout work more cumbersome. When the equipment needs to be moved, the probe rod needs to be frequently inserted. On the one hand, it increases the workload of technicians. On the other hand, longer probe rods are required for some deeper formations. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 A data analysis device for tight sandstone reservoirs includes a protective housing 1 and a surface geophone 9. The surface geophone 9 is connected to a receiving probe 8. An underground geophone 11 and a battery 12 are provided in the protective housing 1. Movable slots 3 are provided at both ends of the protective housing 1. A support component 4 is provided in the movable slot 3. The main body of the support component 4 is located in the protective housing 1, and the front end extends to the outside of the protective housing 1 through the movable slot 3. A drive motor 7 is provided at the front end of the support component 4. A rubber wheel 6 is provided at the output end of the drive motor 7. The rubber wheel 6 is in contact with the inner wall of the pipe.

[0027] In the present utility model, a driving motor 7 and a rubber wheel 6 are provided. When in use, the protective shell 1 is placed in the pipeline, and then the supporting component 4 unfolds the driving motor 7 so that the rubber wheel 6 fits against the inner wall of the pipeline. Then the driving motor 7 works to drive the rubber wheel 6 to rotate. The rubber wheel 6 uses the rotation on the inner wall of the pipeline to move itself. When it moves to a specific position, the driving motor 7 stops working, so that the protective shell 1 is fixed at the detection position, thereby realizing the purpose of autonomous movement of underground equipment in the pipeline, reducing the labor intensity of technicians, and being applicable to detection work at various depths.

[0028] The support component 4 includes a support plate 403 and an electric cylinder 401 arranged in the protective housing 1. A rotating shaft 405 is rotatably provided in the support plate 403. A gear 406 is fixedly provided on the rotating shaft 405. A support frame 404 is provided on the gear 406. The support frame 404 passes through the movable slot 3 and is connected to the drive motor 7. A rack 402 is provided at the front end of the electric cylinder 401 and meshes with the gear 406.

[0029] By providing the support component 4, the support component 4 supports and limits the drive motor 7, and the position of the drive motor 7 can be adjusted, so that the rubber wheel 6 can be suitable for pipes of different diameters. When the rubber wheel 6 needs to be expanded, the electric cylinder 401 drives the rack 402 to move, and the rack 402 drives the support frame 404 to rotate outward and expand through the gear 406, so that the support frame 404 drives the drive motor 7 and the rubber wheel 6 to expand, so that the rubber wheel 6 fits against the inner wall of the pipe, thereby achieving the effect of adjusting the position of the rubber wheel 6, making the application range of the device wider and the moving process more stable.

[0030] A second coil spring 407 is mounted on the side of the rotating shaft 405. The end surface of the second coil spring 407 is connected to the support plate 403, and the second coil spring 407 applies an elastic force to the rotating shaft 405 to rotate outward.

[0031] By setting up the second coil spring 407, the second coil spring 407 uses the elastic force applied to the rotating shaft 405 to keep the rotating shaft 405 and the support frame 404 in an expanded state when there is no external force, thereby reducing the stress on the electric cylinder 401 when the support frame 404 is expanded for a long time, and can reduce the problems of shaking and wobbling during the opening and closing process of the support frame 404.

[0032] The side wall of the movable groove 3 is provided with a sealing groove 14, in which a sealing soft plate 13 is slidably provided, and the sealing soft plate 13 is fixedly connected to the support frame 404;

[0033] By setting the sealing groove 14 and the sealing soft board 13, the sealing soft board 13 is connected to the support frame 404 on the one hand, and slides with the sealing groove 14 on the other hand. When the support frame 404 moves, the sealing soft board 13 will move in the sealing groove 14 at the same time, so that it can fully cover and seal the movable groove 3 without affecting the movement of the support frame 404, thereby reducing the problem of accumulated water and dirt invading the protective shell 1.

[0034] A carrying component 2 is provided on the outside of the protective shell 1. The carrying component 2 is attached to the protective shell 1 without external force. The carrying component 2 includes a connecting seat 202 provided on the side of the protective shell 1. A handle 201 is rotatably provided on the connecting seat 202. The handle 201 is attached to the outer side of the protective shell 1, and a first coil spring 203 is provided between the handle 201 and the connecting seat 202.

[0035] By setting the handle 201 and the first coil spring 203, when transporting, the handle 201 is rotated outward so that the handle 201 is unfolded, and the transport device is squeezed open by the handle 201 on both sides of the protective shell 1. After the transport is completed, when the handle 201 loses the external force, the first coil spring 203 will use its own elastic force to push the handle 201 back to its original position, so that the handle 201 fits against the outside of the protective shell 1, avoiding interference when the device moves in the pipeline.

[0036] Electromagnets 5 are provided at both ends of the protective housing 1 to facilitate grasping the protective housing 1 when taking or placing.

[0037] By setting the electromagnet 5, the electromagnet 5 has magnetism after being energized, so that when placing and removing the device, the magnetism of the electromagnet 5 can be used for adsorption and fixation, without the need for tedious docking work, simplifying the equipment and reducing the influence of unused factors such as sludge on the connection work.

[0038] A sealed compartment 10 is provided in the protective housing 1, and the sealed compartment 10 encloses an underground geophone 11 and a battery 12;

[0039] By setting up the sealed chamber 10, the underground detector 11 and the battery 12 can be further protected by the sealed chamber 10 to avoid water erosion, thereby better ensuring the safe storage and stable operation of the underground detector 11 and the battery 12.

[0040] Working principle: Place the protective shell 1 into the underground pipeline, then the electric cylinder 401 drives the rack 402 to move, and the rack 402 drives the gear 406 to rotate, and the gear 406 drives the support frame 404 to expand outward. The support frame 404 drives the rubber wheel 6 to fit the inner wall of the pipeline through the drive motor 7. During movement, the drive motor 7 drives the rubber wheel 6 to rotate, so that the rubber wheels 6 cooperate with each other to move on the inner wall of the pipeline.

[0041] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
