Description

Technical Field

[0001] The utility model relates to a wireless data acquisition real-time transmission node instrument, in particular to a wireless data acquisition real-time transmission node instrument applied to oil and gas resource exploration, which can be used for oil and gas resource exploration data acquisition. Background Art

[0002] With the decreasing oil and gas resources and the increasing difficulty of development, traditional oil and gas exploration technology is increasingly unable to meet the needs of existing oil and gas exploration. Therefore, the development and innovation of oil and gas exploration technology is of great significance to ensure the sustainable development of national energy. The application of oil and gas resource exploration and development technology is mainly based on geophysical exploration technology. Geophysical exploration technology can effectively explore the physical properties and conditions of underground rocks, thereby assisting oil and gas exploration and development. In view of the complex characteristics of underground geological structures and the unique physical properties of different geological targets, a variety of geophysical exploration technologies such as seismic exploration, gravity exploration, electromagnetic exploration and electrical exploration have emerged. At present, seismic exploration is the most commonly used geophysical exploration technology in oil and gas resource exploration.

[0003] The seismic data acquisition system is the core equipment for realizing seismic exploration, which is mainly divided into wired seismic data acquisition system and wireless seismic data acquisition system. For a long time, seismic exploration usually uses wired seismic data acquisition system to complete data acquisition tasks. The wired seismic data acquisition system connects the detector to the acquisition unit, and the acquisition unit transmits the collected seismic data to the data monitoring vehicle through media such as cables or optical cables. However, as the conventional oil and gas resources that are easy to explore and develop in my country's oil and gas resources are becoming less and less, and the geological conditions of the remaining oil and gas resources are becoming more and more severe, the use of wired seismic data acquisition system faces many problems such as difficult cable laying and low construction efficiency.

[0004] The wireless seismic data acquisition system is also called the wireless seismic data acquisition node. It can be divided into two types according to whether it supports real-time recovery of collected data: wireless non-real-time seismic data acquisition node and wireless real-time seismic data acquisition node. Compared with the wired seismic data acquisition system, the wireless seismic data acquisition system does not require cable or optical cable connection, and has the advantages of flexible layout, lightness, reliability and easy operation. The wireless non-real-time seismic data acquisition system completes data acquisition independently, and stores the collected seismic data in the memory card, waiting for the exploration personnel to uniformly recover all data after the acquisition task is completed. In recent years, with the continuous development of wireless transmission technology, the wireless real-time seismic data acquisition system has become a hot topic in the field of seismic exploration. The wireless real-time seismic data acquisition system transmits the system status or collected data in real time through wireless transmission technology on the basis of independently completing data acquisition. Compared with the wireless non-real-time seismic data acquisition system, it can provide higher data quality control and faster fault detection time. In the prior art, the wireless seismic data acquisition system has problems that need to be optimized, such as low integration, low accuracy of collected data, and inability to support large-scale wireless real-time and reliable transmission of seismic data. Therefore, the existing wireless data acquisition system used in oil and gas resource exploration is difficult to ensure the quality of collected data, and the efficiency of data recovery is low.
