Short summary
Short summary
Our research has developed a new algorithm to improve microseismic signal picking in oil and gas exploration. We use a group theory-based optimization algorithm (GTOA) for signal clustering, combined with the Akaike Information Criterion (AIC) for precise signal picking. Experiments demonstrate that the GTOA algorithm shows better clustering performance across multiple datasets, and the designed algorithm achieves more accurate signal picking under low signal-to-noise ratio conditions.

We developed a software system for a high-precision magnetometer platform, specifically designed for human-occupied vehicles (HOVs). The system integrates magnetometers to deliver accurate magnetic field detection, with advanced features such as automatic probe switching and magnetic compensation. The system's performance was validated through rigorous laboratory tests and marine experiments on the Shenhai Yongshi platform.

We propose a new type of power station unit with wireless data transmission capability, which was not supported by same type of instrument as on the market. Based on this, a novel distributed geophysical data acquisition architecture is also proposed. The proposed instrument loads more stations than the industry-leading LAUL-428 while providing additional wireless data transmission and narrowband Internet of Things remote control.

The expendable current profiler (XCP) is a single-use instrument that rapidly measures currents, including the velocity, flow direction, and temperature of seawater. This study improves upon the design of the XCP to reduce the cost of the single-use devices. This has been achieved by adopting signal modulation and demodulation to transmit analog signals on an enamelled wire and digitizing the signal above the surface of the water.
