| 摘 要： | 近年来,渤海勘探工作者通过转变思路和理论创新,在凹陷内浅层、深层、潜山及稠油油藏等领域发现了一大批大中型油气田:在辽东湾地区发现了全国最大的JZ25-1S混合花岗岩潜山复合轻质油藏,在黄河口凹陷区发现了一大批凹陷内浅层中型油气藏,使黄河口凹陷内部浅层油气藏联成一片;在渤中凹陷北部成功评价了被外方认为没有商业价值的LD27-2、LD32-2大中型稠油油藏,发现了LD27-1中型油气藏。发展和完善了"晚期成藏"理论,并取得了4项创新的地质认识:即断裂与岩性耦合——控制了混合花岗岩潜山油气成藏;"中转站"油气运移——决定了凹陷内上组合油气藏形成;断层—储层组合样式——控制了凹陷内浅层油气富集部位;临界盖层的质量——决定了新近系油藏的商业性。

| Abstract: | In recent years,the Bohai Sea prospectors have discovered a large number of large and medium scale oil-gas fields in shallow layer,deep layers,buried hills,and heavy oil reservoirs in sags,based on thinking changing and theory innovation. The Z25-1S oil-gas field discovered in Liaodong Gulf is the biggest buried-hill composite low-density reservoir of migmatitic granite in China. Large quantities of medium scale reservoirs were discovered in shallow layers in Huanghekou sag area,enabling shallow reservoirs ... |
