基于南黄海盆地海相油气的海洋立体宽线地震勘探技术设想
|
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 hydrocarbon 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.
