Description

Technical Field

[0001] This utility model relates to the field of vibration source equipment technology, and in particular to an ultra-large tonnage shear wave vibrator assembly. Background Technology

[0002] A controlled seismic source is a surface excitation source that needs to adapt to more complex surface excitation conditions. The use of P-wave controlled seismic sources in current exploration technology is widely accepted. Compared to P-wave vibrations, S-wave vibrations have lower wave velocities and shorter wavelengths. Generally, S-wave controlled seismic sources are applied in shallow S-wave seismic exploration and urban exploration. They can identify the location of shallow faults, delineate different engineering geological zones on the seismic profile, and provide reliable geological data for urban earthquake prevention planning, seismic safety assessment, building site selection, and foundation treatment.

[0003] However, with the deepening of oil and gas exploration and the gradual depletion of old oilfields, my country's oil and gas exploration targets have gradually shifted to unconventional oil and gas resources such as deep and ultra-deep oilfields and shale gas. These deep oil and gas resources have complex occurrence conditions and are difficult to explore and develop. The limitations of traditional P-wave seismic exploration technology in identifying unconventional oil and gas reservoirs with complex storage conditions are becoming increasingly apparent. Shear waves, as elastic waves that are sensitive to the rock skeleton structure but not to fluids, have unique advantages in identifying the characteristics of subsurface media. Shear wave sources are also used in multi-wave exploration. Multi-wave exploration is an emerging and promising exploration technology in the world today. It can make up for the shortcomings of P-wave exploration and provide new ideas for direct oil and gas exploration. For example, in the identification of small faults, the joint interpretation of gas layers by P-wave and S-wave profiles, and in some areas with weak P-wave reflection, multi-wave exploration technology can obtain better converted S-wave imaging. Controllable S-wave sources are essential equipment for multi-wave exploration. Utility Model Content

This assembly aims to compensate for the lack of longitudinal waves, enable multi-wave exploration, ensure more stable output, more realistic signals, and achieve ideal exploration results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A super-large tonnage shear wave vibrator assembly includes a counterweight assembly, a plate assembly, an end cap, and a base plate assembly. The counterweight assembly and the plate assembly are connected by the end cap, and the plate assembly and the base plate assembly are connected by bolts. Together, they constitute the shear wave vibrator assembly and realize all the working functions of the shear wave vibrator.

[0007] The hammer assembly includes a hammer body, piston rod, hammer end cap, small copper sleeve, large copper sleeve, cylinder liner, piston ring, oil seal, dust seal, servo valve manifold, servo valve assembly, rubber block, displacement sensor bracket, friction plate, and first mounting hole for hammer accelerometer.

[0011] Preferably, the vibrator assembly has an ultra-high output, with a maximum nominal vibration output of up to 20 tons, which is the highest output among existing transverse wave source vibrator assemblies in China.

[0012] Preferably, the base plate of the flat plate assembly can be replaced with base plate assemblies of different structures to adapt to various construction terrains.

[0013] Preferably, the hammer body is used for oil inlet, abandoning the traditional piston rod oil inlet method. This eliminates the need for oil passage holes inside the piston rod, resulting in greater hardness and better support.

[0014] Preferably, the movement stroke of the counterweight assembly reaches 7 inches, achieving a wider frequency band.

[0015] Preferably, the flat plate assembly has high strength and a rigid structure, resulting in better coupling with the ground.

[0016] Preferably, eight vibration isolation airbag mounting seats are evenly distributed on the flat plate assembly, which makes the flat plate assembly more uniformly stressed, with better vibration effect and less distortion.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting up a powerful power system with a maximum nominal vibration output of 20 tons, it can output super energy in deep, ultra-deep and unconventional oil and gas exploration, overcome complex geological obstacles, penetrate the strata to obtain accurate geological information, make up for the shortcomings of traditional P-wave exploration, improve exploration depth and accuracy, and help to efficiently explore oil and gas resources.

[0019] 2. By setting up a flat plate assembly that can be flexibly fitted with different structural base plate assemblies, the contact method with the ground can be quickly adjusted for diverse terrains such as mountains, plains, and wetlands. This enables it to achieve good ground coupling and stable operation in complex terrains, avoid vibration energy loss and signal distortion, expand its applicable range, and ensure the smooth conduct of multi-wave exploration.

[0034] The end cap 3 includes a connection hole 3-1 with the flat plate assembly, a connection hole 3-2 with the piston rod, a connection stop 3-3 with the piston rod, a connection stop 3-4 with the flat plate assembly, and a process hole 3-5 for removing the end cap;

[0035] The base plate assembly 4 includes a base plate 4-1, a toothed structure welded part 4-2, a hoisting process hole 4-3, and a connecting hole 4-4.

[0036] Furthermore, the vibrator assembly has an ultra-high output, with a maximum nominal vibration output of up to 20 tons, making it the largest output among existing transverse wave source vibrator assemblies in China.

[0037] Furthermore, the base plate of the flat plate assembly 2 can be replaced with a base plate assembly 4 of different structures, thereby adapting to various construction terrains.

[0038] Furthermore, by adopting a hammer-body oil inlet method, the traditional piston rod oil inlet method is abandoned, which eliminates the need to open oil passage holes inside the piston rod, thereby achieving greater hardness and better support effect.

[0039] Furthermore, the travel of the hammer assembly 1 reaches 7 inches, achieving a wider bandwidth.

[0040] Furthermore, the flat plate assembly 2 has high strength and a rigid structure, resulting in better coupling with the ground.

[0041] Furthermore, eight vibration isolation airbag mounting seats are evenly distributed on the flat plate assembly 2, which makes the flat plate assembly more uniformly stressed, with better vibration effect and smaller distortion.

[0042] When using this utility model:

[0043] Reference Figure 1 The ultra-large tonnage transverse wave vibrator assembly is mainly composed of a counterweight assembly 1, a plate assembly 2, an end cap 3, and a base plate assembly 4. The counterweight assembly 1 and the plate assembly 2 are stably connected by the end cap 3, while the plate assembly 2 and the base plate assembly 4 are connected by bolts. All parts work together to form a complete transverse wave vibrator assembly. It is particularly worth mentioning that the vibrator assembly is specially equipped with a limit fixing device, the core function of which is to effectively prevent the counterweight assembly from overturning during the movement process, thereby ensuring the stability and reliability of the equipment operation.

[0044] Reference Figure 2The hammer body 1-1, as the signal source, plays a decisive role in the output tonnage of the vibrator. The piston rod 1-2 plays a dual key role in this vibrator assembly. On the one hand, its rod diameter determines the size of the oil chamber's effective area; on the other hand, it undertakes the important responsibility of connection and support in the entire vibrator assembly architecture. The hammer end cap 1-3 is used to connect the hammer assembly to the plate assembly, and its two ends are designed with stop structures to accurately limit movement. The small copper sleeve 1-4 and the large copper sleeve 1-5 effectively prevent friction damage to the piston rod caused by the transverse wave hammer under gravity during hammer movement, providing good protection. The large copper sleeve 1-5 also has an oil inlet and outlet port, through which hydraulic oil can be entered and exited, and high and low pressure hydraulic oil can be switched. The cylinder liner 1-6 cooperates with the piston rod to accurately determine the size of the piston area and determine the range of the hammer's stroke. The piston ring 1-7 is located inside the oil chamber and undertakes the dual functions of sealing and sliding. Its effective operation ensures normal switching of hydraulic oil, providing a solid guarantee for the stable output of the vibrator. The setting of two oil seals 1-8 can effectively prevent hydraulic oil leakage; the dustproof ring 1-9 can effectively block dust from entering the system and avoid system contamination. The servo valve manifold 1-10 is responsible for realizing the oil inlet and outlet operation of the hammer and, through the connection of the rubber hose, maintains the normal operation of the hydraulic system. The servo valve assembly 1-11, with the help of hydraulic servo control technology, can effectively ensure that the vibrator assembly can work stably and efficiently. The rubber block 1-12 plays a key role in calibration, effectively buffering the impact force generated between the hammer and the plate, and protecting the equipment. The displacement sensor bracket 1-13 is used to install the displacement sensor to support the monitoring of the equipment's operating status. The friction plate 1-14 provides a friction surface for the limit device. Through the interaction between the two, the hammer is effectively prevented from overturning. The first mounting hole 1-15 of the hammer accelerometer is used to install the hammer accelerometer for accurate measurement of relevant parameters.

[0045] Reference Figure 3Both the left and right flat plate assemblies 2-1 and 2-2 are welded together, assembling all components into a single unit to ensure proper functioning. The accelerometer mounting hole 2-3 provides a convenient way to replace or install a counterweight accelerometer. The cleaning hole 2-4 is used to clean accumulated debris inside the flat plate assembly, keeping the equipment clean. The base plate connecting plate 2-5 has mounting holes for installing the base plate assembly, significantly enhancing its rigidity within the flat plate assembly. The connecting plate 2-6 plays a role in connecting the left and right flat plates, acting as a precise reference positioning component in the welded parts. Airbag connectors A2-7 and B2-8 are mainly used to connect vibration isolation airbags during the assembly of the vibration source, improving the equipment's vibration isolation performance. Displacement sensor mounting holes are also present. 2-9 is used to install displacement sensors to support equipment operation status monitoring. Limit mounting hole 2-10 is used to install limit devices to effectively ensure that the movement direction of the hammer meets the design requirements. Limit plate 2-11 plays a limiting role when connected to the lower frame. Second mounting hole 2-12 for the hammer accelerometer and mounting hole 2-15 for the flat plate accelerometer are used to install the hammer accelerometer and the flat plate accelerometer, respectively, to achieve accurate measurement of parameters in different parts. End cap connection hole 2-13 is used to connect the end cap. Indicator seat connection hole 2-14 is used to install an indicator for checking the polarity direction of the hammer during calibration. Displacement sensor seat connection hole 2-16 and indicator mounting hole 2-17 are used to install displacement sensors and indicators, respectively, to provide comprehensive support for equipment commissioning and operation monitoring.

[0046] Reference Figure 4 The connection holes 3-1 and 3-4 with the flat plate assembly are used to achieve a stable connection between the end cap and the flat plate, and play a reliable limiting role during the connection process. The connection holes 3-2 and 3-3 with the piston rod are used to connect the end cap and the piston rod, and also have a precise limiting function. The process hole 3-5 for removing the end cap plays a role when removing the end cap, providing convenience for equipment maintenance.

[0047] Reference Figure 5The base plate assembly 4 integrates the various components into a cohesive whole through welding. The base plate 4-1 plays a crucial role in the entire system, providing a stable connection to the flat plate assembly. As a key main component during welding, it possesses high strength. The toothed structure welded component 4-2 is formed with the required tooth angle and structure through welding to meet specific operational needs. The lifting process hole 4-3 is used during equipment processing or disassembly to facilitate equipment handling and installation. The connection hole 4-4 is used to connect to the flat plate assembly, ensuring the structural integrity of the entire system. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
