摘　　要：南方海相碳酸盐岩油气勘探历史较长,以前虽有所发现,但规模有限。近几年来,随着三维地震勘探技术的发展及其在南方复杂山地的大规模实施,中国石油化工股份有限公司相继在川东北地区海相油气勘探领域取得了巨大发现。勘探实践表明,三维地震勘探技术大幅度改善了该地区的地震资料品质,为解决复杂地质问题奠定了良好的资料基础,从而提高了碳酸盐岩储层预测和描述的精度,大大加快了油气勘探节奏。从普光大型气田的探明到元坝大型礁滩体的发现,充分表明三维地震勘探技术在南方复杂海相油气勘探中发挥了不可替代的作用。The marine carbonate reservoir exploration of Southern China has long history,some discoveries were achieved,but the scale is limited.In recent years,along with the development of 3D seismic exploration techniques and their large-scale implementation in south complicated mountainous area,SINOPEC achieved tremen- dous discoveries in Northeast Sichuan area.Exploration practice indicates that 3D seismic exploration techniques can largely improve seismic data quality,provide good data foundation for solving complicated geological problems and improve the accuracy of carbonate reservoir prediction and characterization,which largely increase the exploration speed.The discovery of Puguang gasfield and Yuanba reef-flat reservoir sufficiently proved that 3D seismic exploration techniques displayed non-replaceable function in complicated marine reservoir exploration of southern China.
