Abstract：
This article introduces a cable-free real-time telemetry seismic acquisition system (hereinafter referred to as the cable-free real-time telemetry system) that utilizes 4G/5G technology. This system facilitates the real-time acquisition and quality control of seismic data, the real-time monitoring of equipment location and health status, the synchronous transmission of collected data between the cloud and client, and the realtime issuance of operational instructions. It addresses the critical limitation of existing seismic node equipment, which is often restricted to mining and blind storage due to the absence of a wired or wireless communication link between the acquisition node device and the central control unit. This limitation necessitates local data storage and rendering real-time quality control unfeasible. Typically, quality control is conducted post-task completion, requiring the overall retrieval and downloading of data. If data issues are identified, it becomes necessary to eliminate faulty tracks and determine the need for supplementary acquisition, which can lead to delays in the acquisition process. The implementation of real-time monitoring and early warning systems for equipment health status aims to mitigate the risk of poor data quality resulting from equipment anomalies. Furthermore, the real-time synchronous transmission between the cloud and server addresses the bottleneck of slow download speeds associated with the centralized retrieval of data from multiple node devices during blind acquisition and storage. A real-time microseismic data acquisition test and verifi cation were conducted at a fracturing site in an eastern oil and gas fi eld. Analysis of the test data indicates that the overall performance indicators of the system are comparable to those of existing mainstream system equipment, demonstrating stability and reliability. The performance parameters fully satisfy the technical requirements for oilfield fracturing monitoring scenarios, suggesting promising prospects for further promotion and application.
