Marine Mesozoic-Paleozoic strata, as a favorable exploration target, are well developed on the Laoshan uplift of South Yellow Sea Basin. However, due to the existence of seismic shield at the bottom of the Cenozoic, seismic waves are difficult to penetrate through the boundary, that have caused the decrease in image quality and signal-noise ratio of seismic profiles. In order to improve the quality of seismic data, the domestic "HQI-Seis" high-precision streamer acquisition system was adopted in this project to increase the spatial sampling rate and improve the signal to noise ratio. At the same time, proper acquisition parameters are designed and optimized for the same purpose. The practice proves that the endeavor has obviously improved the quality of seismic data and Mesozoic images from the Laoshan uplift and it is certainly helpful to Mesozoic exploration in this region.
