摘　　要：南黄海盆地中—古生代海相碳酸盐岩具有良好的油气前景,由于埋藏深、厚度大、构造复杂等特殊地震地质条件的原因,地震原始资料品质差,严重地制约了勘探进程。综合常规宽线和上下缆勘探技术的优势,提出了海洋立体宽线(MTBL)地震勘探新技术设想,对其改善地震资料品质的作用和优势进行了分析,为南黄海海相油气地震的勘探工作者提供了参考。It is believed that the Paleozoic and Mesozoic marine carbonate reservoir bears great hydro- carbon potential in the Southern Yellow Sea Basin （SYSB）. However, due to the Large burial depth, the large thickness and the complexity of geological structure of the Mesozoic-Paleozoic, high quality seismic data are hard to be acquired using conventional seismic prospecting method, and it has become a bottleneck to the hydrocarbon exploration in this region. The authors suggest in this paper setting up a seismic prospecting system, namely the Marine Tridimensional Wide Line（MTWL）technique, which combines the advantages of the traditional land wide line technique together with the over/under streamer method, to improve the quality of seismic data so as to push forward the hydrocarbon exploration on marine carbonate reservoirs in the South Yellow Sea basin.
