Description

Technical Field

[0001] This utility model belongs to the technical field of geophysical exploration and collection stations, specifically relating to a blind collection station suitable for deployment in water areas. Background Technology

[0002] As oil, gas, and mineral resource exploration and development deepen, exploration targets are becoming increasingly complex, exhibiting characteristics such as thinness, small size, fragmentation, dispersion, depth, and concealment. Traditional seismic techniques can no longer meet the needs of identifying and describing increasingly complex geological targets. Under the backdrop of high-precision exploration, harsh surface conditions, complex underground structures, and reservoir storage spaces present new challenges to efficient geophysical operations, placing increasingly higher demands on seismic instruments. High-density, high-volume, and nodal acquisition technologies are crucial methods for achieving efficient and low-cost operations under conditions of "dual complexity." Due to the industry's continuously increasing demand for high-density seismic acquisition and the ongoing advancements in efficient and controllable source technology at the excitation end, wired acquisition systems at the receiving end can no longer keep pace with the rapid development of ultra-high-density acquisition, leading to a growing demand for smaller and lighter blind acquisition nodes.

[0003] Small blind acquisition stations break through traditional size and weight limitations, providing high-density, large-scale seismic acquisition for various complex terrains with lower cost and less environmental footprint.

[0004] However, high-density, high-volume seismic acquisition often encounters deployment challenges in aquatic environments such as lakes, reservoirs, streams, swamps, and shallows. Therefore, blind acquisition stations need to have the capability for deployment in such environments. Generally, the following deployment schemes are available: The first method is to deploy underwater node-type data collection stations (OBN / OBS) in the water area. The second method is to deploy buoy-type data collection stations in the waters; The third method is to deploy the sensor on the bottom of the water, and then connect it to the blind sampling station through a cable and plug. The sampling station is then placed on a float and allowed to float on the water surface.

[0005] The first two types of data collection stations are expensive and have high maintenance costs, while the third type of data collection station deployment method is more economical.

[0006] While the third approach is economically superior, it faces an engineering challenge: most of the existing ground-based wireless geophysical data acquisition stations, geophysical sensors, and instruments have their external KCK socket interfaces on the upper housing. For instruments with external KCK socket interfaces on the upper housing, a KCK plug and cable need to be plugged in when connecting external sensors to the KCK socket interface.

[0007] Because blind sampling stations are often small and lightweight, and the external plugs and cables need to be connected to the sensors on the bottom of the water, the plugs and cables will generate a tipping moment on the blind sampling station, making the station prone to tipping over. This requires larger and heavier floats to keep the sampling station floating vertically on the water surface, which makes large-scale deployment, transportation and recovery difficult. Utility Model Content

[0008] The purpose of this invention is to provide a blind sampling station suitable for deployment in water areas, in order to solve the aforementioned problems existing in the prior art.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A blind sampling station suitable for deployment in water areas includes a detachably connected upper shell and a lower shell. A main unit module is installed inside the upper shell, and a sensor module is mounted on the lower shell. The sensor module includes a built-in sensor or an external sensor interface. The external sensor interface is installed on the bottom outer wall of the lower shell and is used to connect to a detector plug. The plug is pre-installed at the end of a cable, ensuring that when the sampling station is in a vertical position, the line of action of the overturning force generated by the connection is vertically downward and close to the center of gravity of the sampling station. A float is installed on either the upper or lower shell to provide buoyancy for the entire sampling station.

[0010] Furthermore, the host module includes a control unit, a data acquisition unit, a power supply module, and a GPS module. The control unit is used to regulate the overall operating logic of the data acquisition station, the data acquisition unit is used to receive and process vibration signals, the power supply module is used to provide long-term power supply, and the GPS module is used to realize the positioning of the data acquisition station.

[0011] Furthermore, the built-in sensor is installed inside the lower housing, with the sensor's detection end facing the bottom of the lower housing.

[0012] Furthermore, the external sensor interface is a KCK external interface, which is connected to the detector located at the bottom of the water via a KCK plug and cable to ensure the stability and reliability of signal transmission.

[0013] Furthermore, both the upper and lower shells are made of environmentally friendly polymer engineering plastics. These environmentally friendly polymer engineering plastics can maintain preset impact toughness and structural strength within an ambient temperature range of -40℃ to 70℃, and their strength and insulation do not decrease when immersed in water for a long time.

[0014] Furthermore, the upper and lower housings are detachably connected by bolts.

[0015] Beneficial effects: This blind sampling station, suitable for deployment in water areas, features an external sensor interface located at the bottom of the lower casing. This low-profile design ensures that when the station is in a vertical position, the line of action of the overturning force generated by the connection is vertically downward and close to the station's center of gravity, greatly enhancing the station's anti-overturning capability in water. Furthermore, the sensor module includes both built-in and external sensor interfaces, allowing users to flexibly choose according to different exploration needs.

[0016] The outer shell is made of special engineering plastic that is resistant to high and low temperatures and water immersion, and is equipped with a float, enabling the collection station to work reliably in various aquatic environments. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Example: Example 1 like Figures 1-5 As shown, this embodiment provides a blind data collection station suitable for deployment in water areas, including a detachably connected upper shell 1 and a lower shell 2. The upper shell 1 houses a host module responsible for data collection, processing, and control.

[0024] The main unit module includes a control unit, a data acquisition unit, a power supply module, and a GPS module. The control unit is used to regulate the overall operation logic of the data acquisition station, the data acquisition unit is used to receive and process vibration signals, the power supply module is used to provide long-term power supply, and the GPS module is used to locate the data acquisition station for easy retrieval and recovery.

[0025] The lower housing 2 is equipped with a sensor module for receiving vibration signals. This sensor module can be selected to use either a built-in sensor or to be connected to an external detector through an external sensor interface 3. In this embodiment, an external sensor interface 3 is selected. The external sensor interface 3 is installed on the bottom of the outer wall of the lower housing 2. This unique low-position design ensures that when the plug 5 and cable 6 of the external detector are connected to this interface, the overturning force generated by the connection is vertically downward and close to the center of gravity when the acquisition station is in a vertical position. This design can significantly improve the stability of the acquisition station in water, effectively resisting the shaking or overturning caused by external factors such as water flow and waves, thereby allowing the sensor to effectively receive seismic wave signals reflecting geological structures from deep underground.

[0026] Furthermore, the external sensor interface 3 allows users to quickly change the type of sensor at the data acquisition station to adapt to on-site production needs, which can greatly improve the flexibility of the blind data acquisition station.

[0027] Preferably, the external sensor interface 3 is a KCK external interface, which is connected to the detector located on the bottom of the water through a KCK plug and cable 6. This interface has the advantages of reliable connection and good waterproof performance, ensuring the stability and reliability of signal transmission.

[0028] Furthermore, to ensure that the data collection station can stably float at a preset depth in the water or float on the surface, a float 4 is installed on the upper shell 1 or the lower shell 2 to provide the necessary buoyancy for the entire data collection station. The position and buoyancy of the float 4 can be adjusted as needed to achieve the optimal deployment posture.

[0029] Both the upper shell 1 and the lower shell 2 are made of environmentally friendly high-polymer engineering plastic. The environmentally friendly high-polymer engineering plastic can maintain the preset impact toughness and structural strength within an ambient temperature range of -40℃ to 70℃, and its strength and insulation do not decrease when immersed in water for a long time, thus ensuring the service life and safety of the data collection station.

[0030] The upper housing 1 and the lower housing 2 are detachably connected by bolts, which facilitates subsequent maintenance and replacement of the various internal modules.

[0031] Example 2 The difference between this embodiment and Embodiment 1 is that the built-in sensor is installed inside the lower housing 2, with the sensor's detection end facing the bottom of the lower housing 2 to better receive vibration signals from the ground. Commonly used sensors can be selected in the built-in mode.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
