Description

Technical Field

[0001] This application relates to the technical field of seismic exploration equipment, and more particularly, to a geophysical exploration shot hole cleaning device. Background Art

[0002] During the construction of oil geophysical exploration drilling, affected by geological conditions, the completed wellbore wall is prone to collapse or bottom sediment deposition problems, resulting in a shallower well depth, which affects the inability of the explosive column to reach the bottom of the well, resulting in poor excitation effects. In more serious cases, the explosive cannot be placed, resulting in the abandonment of the wellhead and the need to drill a new well. Therefore, before the explosive placement process, it is necessary to wash the wellheads whose well depth quality does not meet the requirements for explosive placement.

[0003] Due to the small diameter of the geophysical exploration shot hole, the current method for cleaning the geophysical exploration shot hole is to directly insert a water pipe into the geophysical exploration shot hole for flushing. To a certain extent, it can remove the sediment in the geophysical exploration shot hole. However, in actual use, it is found that this cleaning method has the following technical problems: the soft water pipe is difficult to reach the bottom of the geophysical exploration shot hole, and the cleaning effect on the bottom of the geophysical exploration shot hole is poor. Especially when there are large particle cuttings at the bottom of the geophysical exploration shot hole, it takes a long time and a large amount of water to flush out the sundries in the geophysical exploration shot hole, resulting in problems such as low cleaning efficiency, poor cleaning effect, and large water consumption. Utility Model Content

[0004] The purpose of this application is to provide a geophysical exploration shot hole cleaning device, aiming to solve the problems that the water pipe is difficult to reach the bottom of the well and the cleaning efficiency is low.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] As Figure 1 shown, the present application provides a geophysical exploration shot hole cleaning device, including: a spray head body 1 and an extension rod.

[0029] The interior of the spray head body 1 is hollow. One end of the spray head body 1 is provided with a first connection port 19 and a water inlet, and the first connection port 19 is connected to the extension rod. One end of the spray head body 1 away from the water inlet is provided with a conical part 12. A plurality of first spray holes 14 are opened on the side wall of the conical part 12, and the first spray holes 14 are inclined towards the end of the conical part 12 away from the first connection port 19. A second spray hole 15 is opened at the end of the conical part 12 away from the first connection port 19.

[0030] The nozzle body 1 is used to spray water into the geophysical exploration shot hole when cleaning it, so as to wash the sundries in the geophysical exploration shot hole. The first connection port 19 and the water inlet are respectively used to connect the extension rod and the water pipe. The extension rod is used to send the nozzle body 1 into the geophysical exploration shot hole, and the water pipe is used to follow the nozzle body 1 into the geophysical exploration shot hole and supply water to the nozzle body 1. The tip of the conical part 12 is arranged so that it can more easily penetrate into the sundries at the bottom of the geophysical exploration shot hole, especially those deposited at the bottom of the well and difficult to reach areas. It enhances the impact force and penetration power of the water flow on the bottom sundries, thus improving the cleaning effect. The shape of the conical part 12 makes the whole nozzle body 1 more stable when penetrating into the bottom of the well and is not easily disturbed or blocked by the sundries at the bottom of the well. It can maintain the continuity and stability of the water flow, thereby further improving the cleaning efficiency. As the lowermost part of the nozzle body 1, the conical part 12 is in direct contact with the bottom of the well. Its solid structure can withstand the impact and abrasion of the sundries at the bottom of the well, thus protecting other parts of the nozzle body 1 from damage and extending the service life of the nozzle body 1. Due to the guiding property of the conical design of the conical part 12, the nozzle body 1 can more easily penetrate into the bottom of the well and adapt to the bottom of the well with different shapes and sizes, so the nozzle body 1 has strong adaptability. Whether in a geophysical exploration shot hole with a smaller or larger diameter, effective cleaning can be achieved.

[0031] The first spray holes 14 and the second spray holes 15 are used to spray water into the geophysical exploration shot hole, so as to wash the sundries in the geophysical exploration shot hole. The first spray holes 14 spray water obliquely downward, so that it can not only wash the sundries at the bottom of the geophysical exploration shot hole, but also take into account the cleaning of the well wall. When there is sediment or small sundries attached to the well wall, the obliquely downward water flow can effectively peel off and carry away these impurities. The arrangement of multiple first spray holes 14 can form a wide cleaning coverage area, ensuring that every corner of the bottom and side walls can be fully washed, thus improving the overall cleaning effect. The obliquely downward water flow produces a scouring effect on the well wall, accelerating the movement and discharge of the sundries, further shortening the cleaning time and improving the working efficiency. The second spray holes 15 are arranged at the tip of the conical part 12 and spray water vertically downward, specifically targeting the stubborn sundries at the bottom of the geophysical exploration shot hole. This can ensure that the bottom sediments, large particle cuttings, etc. are directly and efficiently washed away. When there are large sundries or sediments that are difficult to scour at the bottom of the geophysical exploration shot hole, the vertically downward water flow can generate a stronger impact force, which helps to

[0032] remove these impurities faster and more thoroughly. The arrangement of the second spray holes 15 reduces the blind spots and dead corners of the bottom cleaning, improves the comprehensiveness and efficiency of the cleaning, and further reduces the water consumption and cleaning time.

[0033] When cleaning a geophysical exploration shot hole, connect the nozzle body 1 to the lower end of the extension rod and connect a water pipe to the water inlet. Then, the nozzle body 1 of the geophysical exploration shot hole can be inserted into the geophysical exploration shot hole, and water is injected into the nozzle body 1 through the water pipe, and the nozzle body 1 is sent to the bottom of the geophysical exploration shot hole. During this process, the water flow ejected from the first spray holes 14 and the second spray holes 15 is used to clean the geophysical exploration shot hole, and the cleaning of the geophysical exploration shot hole can be completed faster and better.

[0034] Furthermore, the first connection port 19 is adjacent to the water inlet, and the central axis of the first connection port 19 coincides with the central axis of the conical part 12. The first connection port 19 and the water inlet are both on the same end face, that is, the upper end of the nozzle body 1. In this way, the water pipe connected to the water inlet will be juxtaposed with the extension rod, preventing the water pipe from being scratched when the nozzle body 1 is sent into the geophysical exploration shot hole.

[0035] Specifically, the nozzle body 1 includes a first body 11 and a second body 16 fixedly connected to the outside of the upper part of the first body 11. A first flow channel 13 extending in the up and down direction is provided in the first body 11. The first connection port 19 is provided at the upper end of the first body 11. The water inlet is provided at the upper end of the second body 16. A second flow channel 17 extending downward from the water inlet is provided in the second body 16. A communication port 18 for communicating the first flow channel 13 and the second flow channel 17 is provided at the connection part of the first body 11 and the second body 16. The second flow channel 17, the communication port 18 and the first flow channel 13 form a medium flow channel.

[0036] By arranging the water inlet and the first connection port 19 adjacent to each other, the space occupied by the upper part of the nozzle body can be reduced, making the overall structure more compact and facilitating operation in a narrow geophysical exploration shot hole. Since the water inlet is directly connected to the medium flow channel inside the nozzle body 1 and its position coincides with the central axis of the conical part 12, this design helps to ensure that the water flow can smoothly flow from the water inlet to the spray holes (the spray holes are the general term for the first spray holes 14 and the second spray holes 15) of the conical part 12, reducing the resistance and energy loss of the water flow in the flow channel. The coincidence of the central axis of the first connection port 19 and the central axis of the conical part 12 means that the nozzle body 1 can maintain a good centering state during installation and use, so that the water flow ejected from the spray holes can more concentratedly act on the bottom and side walls of the geophysical exploration shot hole, thereby improving the cleaning effect. The adjacent and aligned design makes the installation and maintenance of the nozzle more simple. For example, when connecting the water pipe and the extension rod, it is easier to ensure that the connection part with the nozzle body is well sealed, preventing water leakage or loosening. When the nozzle body 1 is inserted into the geophysical exploration shot hole through the extension rod for cleaning operations, the overlapping setting of the central axes helps to maintain the stability of the nozzle, reducing the offset caused by vibration or water flow impact, thereby further improving the efficiency and safety of the cleaning operation.

[0037] Such as Figure 2 AndFigure 3 As shown, further, a pipe joint 2 is provided at the water inlet. The pipe joint 2 is installed at the water inlet of the spray head body 1 and is used to connect to an external water pipe. In this way, the water source can smoothly enter the spray head body, ensuring the normal progress of the cleaning operation.

[0038] Specifically, the lower end of the pipe joint 2 is provided with a first external thread, and the inner wall of the water inlet is provided with a first internal thread. The lower end of the pipe joint 2 and the water inlet are fixedly connected by means of thread fitting. In order to improve the sealing performance, a sealing member can also be provided between the lower end of the pipe joint 2 and the water inlet. The sealing member can be composed of PTFE tape or sealant. Through the thread fitting method, the pipe joint 2 can be quickly and conveniently connected to the spray head body, and can also be easily disassembled. This design improves the efficiency of the cleaning work and reduces the time waste caused by inconvenient disassembly and assembly. The pipe joint 2 and the water inlet are tightly fitted by threads and may be equipped with a sealing member (such as PTFE tape or sealant) to ensure the water tightness of the connection. This avoids the reduction in efficiency and potential safety hazards caused by water leakage during the cleaning process.

[0039] The quick disassembly and assembly characteristics of the pipe joint 2 make the installation and replacement of the cleaning spray head more convenient, thus improving the overall work efficiency. Due to the good sealing performance of the pipe joint 2, the equipment damage and maintenance requirements caused by water leakage are reduced, thereby reducing the maintenance cost. The good water tightness avoids situations such as water leakage or splashing during high-pressure cleaning. The setting of the pipe joint 2 takes into account various usage scenarios and requirements, can adapt to water pipes and spray heads of different specifications, and improves the versatility and flexibility of the equipment.

[0040] Further, a rod joint 3 is provided at the first connection port 19. The rod joint 3 is used to connect to an extension rod. This enables the spray head to be stably installed at the lower end of the extension rod, so that it can penetrate into the geophysical exploration shot hole for cleaning.

[0041] Specifically, the rod joint 3 is a component fixedly connected to the first connection port 19 by means of threaded connection. The lower end of the rod joint 3 is provided with a first threaded head 31, and the inner wall of the first connection port 19 is provided with an internal thread. The first threaded head 31 and the first connection port 19 are fixedly connected by means of thread fitting. Further, when using a steel pipe or other pipe materials to form the spray head body 1 and using the inner cavity of the steel pipe or other pipe materials to form the medium flow channel, a solid rod joint 3 can be used to block the opening at the upper end of the pipe.

[0042] The setting of the rod joint 3 makes the connection between the extension rod and the nozzle body 1 simple and quick, and improves the work efficiency. When it is necessary to clean the gun wells of different depths, the extension rods of different lengths can be easily replaced. Through the connection of the rod joint 3, a stable support structure is formed between the extension rod and the nozzle body 1, which increases the stability during the cleaning process and avoids poor cleaning effect or equipment damage caused by vibration or instability. The universal design of the rod joint 3 allows it to be used in conjunction with various types of extension rods, enhancing the applicability and flexibility of the entire cleaning device.

[0043] like Figure 4 As shown, in an optional embodiment, the nozzle body 1 includes a first steel pipe section 4 and a second steel pipe section 6 arranged in parallel, the first connection port 19 is arranged at one end of the first steel pipe section 4, the water inlet is arranged at one end of the second steel pipe section 6, and the first steel pipe section 4 is connected to the second steel pipe section 6. The nozzle body 1 also includes a steel rod section 5, which is arranged at one end of the first steel pipe section 4 away from the first connection port 19, and a tapered portion 12 is formed at one end of the steel rod section 5 away from the second steel pipe section 6.

[0044] The first steel pipe section 4 and the second steel pipe section 6 are fixedly connected by a specific connection method (such as welding), and their inner cavities together constitute a part of the medium flow channel. In this way, water can flow smoothly from the water inlet of the nozzle body, and flow to the lower end of the nozzle body through this medium flow channel to achieve the cleaning function. Through the segmented design, the first steel pipe section 4 and the second steel pipe section 6 can be targeted at their respective locations for strengthening treatment to adapt to different working environments and requirements. For example, the wall thickness can be increased or higher strength materials can be used in the parts that need to withstand greater pressure or impact force, thereby improving the structural strength and service life of the entire nozzle. The segmented setting makes the manufacturing process of the nozzle body 1 more flexible and convenient. Each steel pipe section can be processed and manufactured separately, and then combined together by a connection method. In addition, if a steel pipe section is damaged or fails during use, it can also be more easily repaired or replaced, reducing the cost and difficulty of maintenance.

[0045] Furthermore, the connection between the steel rod segment 5 and the second steel pipe segment 6 can be a detachable connection. The detachable connection allows the steel rod segment 5 to be easily removed from the second steel pipe segment 6 when necessary, which facilitates the maintenance and care of the nozzle, such as cleaning and replacement of worn parts. With the detachable connection design, steel rod segments 5 of different lengths can be selected according to actual needs to meet the cleaning needs of geophysical blastholes of different depths, thereby improving the flexibility of the device. During transportation or storage, the detachable connection can reduce the risk of damage caused by the overall size being too large, because each part can be packaged and stored separately.

[0046] Further, a first straight hole 51 is vertically formed inside the steel rod section 5 along the central axis of the steel rod section 5. The first straight hole 51 communicates with the first spray hole 14 to form a second straight hole 53, and the first straight hole 51 communicates with the second spray hole 15 to form a third straight hole 54.

[0047] Specifically, a first communication hole 43 is provided at the lower part of the first steel pipe section 4, and a second communication hole 62 is provided at the lower part of the second steel pipe section 6. The inner cavity of the first steel pipe section 4 is the first steel pipe inner cavity 41, and the inner cavity of the second steel pipe section 6 is the second steel pipe inner cavity 61. The second steel pipe inner cavity 61, the second communication hole 62, the first communication hole 43, the first steel pipe inner cavity 41, and the first straight hole 51 constitute a medium flow channel. The second steel pipe inner cavity 61 constitutes the second flow channel 17 of the medium flow channel. The second communication hole 62 and the first communication hole 43 constitute the communication port 18 of the medium flow channel. The first steel pipe inner cavity 41 and the first straight hole 51 constitute the first flow channel 13. The first steel pipe upper port 42 of the first steel pipe section 4 constitutes the first connection port 19, and the second steel pipe upper port 63 of the second steel pipe section 6 constitutes the second connection port 110 (i.e., the water inlet). A tapered surface 52 is machined at the lower end of the steel rod section 5 to form the tapered portion 12. The lower end of the steel rod section 5 is provided with a second straight hole 53 and a third straight hole 54. The second straight hole 53 constitutes the first spray hole 14, and the third straight hole 54 constitutes the second spray hole 15.

[0048] The first straight hole 51 is the main channel for the medium to flow in from the water inlet and finally spray out through the spray holes. It connects the upper and lower parts of the nozzle body 1, ensuring the smooth flow of water. By adjusting the diameter of the first straight hole 51, the medium flow rate through the nozzle can be controlled, thereby adjusting the flushing intensity and effect of the nozzle. A larger diameter allows more water to pass through, enhancing the flushing ability; while a smaller diameter helps to save water resources and reduce water consumption during the flushing process. Compared with the smaller second straight hole 53 and third straight hole 54, the larger diameter of the first straight hole 51 ensures that the water has sufficient pressure and flow rate before reaching the tapered portion, so as to be able to more effectively flush the debris at the bottom of the geophysical exploration shot hole. During the manufacturing process, the first straight hole 51 can be relatively easily formed by drilling, and its diameter can be adjusted according to actual needs. In addition, since the first straight hole 51 is located inside the steel rod section 5, its structure is relatively simple, facilitating later maintenance and cleaning. The tapered portion 12 and the steel rod section 5 are designed as solid materials in the area excluding the first straight hole 51. This design significantly enhances the overall strength and stiffness of the nozzle. The solid structure can better resist external impacts and internal pressures, reducing the risk of deformation or damage of the nozzle caused by uneven stress during use. Due to the solid design of the tapered portion 12 and the steel rod section 5, the nozzle can maintain stable performance and flushing effect during long-term use, thereby extending the service life of the nozzle.

[0049] Such as Figure 5 and Figure 6As shown, further, the extension rod includes multiple rod units 7, and two adjacent rod units 7 are detachably connected. The design of multiple rod units 7 enables the entire extension rod to be split into multiple smaller parts, facilitating carrying and transportation in the field construction environment. By connecting different numbers of rod units 7, the total length of the extension rod can be flexibly adjusted to meet the requirements of geophysical exploration shot hole cleaning at different depths. When cleaning deeper shot holes, more rod units 7 can be quickly connected to reach the required depth, reducing the time wasted due to replacing cleaning rods of different lengths. Compared with manufacturing a single long rod, manufacturing multiple shorter rod units 7 and connecting them when needed is more economical and efficient because the manufacturing, storage, and transportation costs of shorter rod units 7 are usually lower. The detachable connection design makes the extension rod easier to maintain and replace. If a rod unit 7 is damaged, only this unit needs to be replaced instead of the entire extension rod, thus reducing the maintenance cost and time. By adjusting the number and connection sequence of rod units 7, the position and angle of the cleaning nozzle can be more easily controlled, thereby optimizing the cleaning effect on the bottom and side walls of the geophysical exploration shot hole.

[0050] Specifically, the rod unit 7 includes a rod body 71, a male connector 72, and a female connector 73. The male connector 72 and the female connector 73 are respectively provided at both ends of the rod body 71, and the male connector 72 and the female connector 73 are provided with mutually matching threads. The upper end of the rod joint 3 is provided with a second threaded head 32, and the second threaded head 32 is thread-matched with the female connector 73. Threaded connection allows for quick and convenient connection and disassembly between rod units 7, which can be completed without additional tools, improving work efficiency. Through the tight fit of the threads, a firm connection between rod units 7 can be ensured, preventing loosening or falling off during use due to vibration or external forces. Since the length of the rod unit 7 can be standardized, different numbers of rod units can be combined to adapt to geophysical exploration shot holes of different depths, improving the applicable range of the device.

[0051] In an alternative embodiment, the length of each rod unit 7 is not less than 1.5 m and not greater than 2 m. In specific implementation, the length of the rod unit 7 is usually set between 1.5 m and 2 m. When the length of the rod unit 7 is greater than 2 m, the disassembly, assembly, and transportation are more difficult. When the length of the rod unit 7 is less than 1.5 m, the disassembly and assembly process is more cumbersome. Setting the length of the rod unit 7 between 1.5 m and 2 m ensures the convenience of disassembly and assembly of the rod unit 7.

[0052] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.

[0053] It should also be noted that in this text, the orientation or positional relationships indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the present application. In addition, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Nor can it be construed as indicating or implying relative importance. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent in such process, method, article or terminal device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or terminal device comprising the element.
