Abstract: In view of the relatively low degree of prospecting, neritic areas in China still hold significant potential of hydrocarbon exploration. Ocean bottom cable (OBC) acquisition is a routine centralized cabled method plagued by operational complexities and low efficiency. In contrast, ocean bottom node (OBN) approach has the advantages of high efficiency, low cost, and multicomponent data acquisition. OBN acquisition technology has developed rapidly in recent years. Sinopec Geophysical Corporation has successfully developed a new-type shallow-sea OBN, named I-OBN. By integrating three key timing strategies (external GNSS synchronization, internal high-precision oven-controlled crystal oscillator timekeeping, and time drift correction), I-OBN effectively resolves the challenge of maintaining underwater high-precision timekeeping. To verify its acquisition performance, this study performs a comparative field test in neritic CD area of the Bohai Bay between I-OBN and GPR300 (a commercial foreign OBN type) in terms of technical specifications and physical parameters. The processing and analysis results of the acquired data demonstrate fundamentally equivalent data quality of I-OBN and GPR300. As shallow-sea exploration increasingly adopts OBN technique, the developed I-OBN shows promising application prospects.
