岩性地层油气藏地质理论与勘探技术

中国陆上剩余油气资源主要分布在中低丰度岩性地层油气藏领域，勘探潜力巨大。针对中国陆上陆相断陷、坳陷、前陆和海相克拉通等4类原型盆地和砂砾岩、火山岩、缝洞型碳酸盐岩储集体中岩性地层油气藏的勘探，通过5年系统研究，在地质理论、技术创新与生产实效等方面取得重大成果：①系统建立了4类盆地岩性地层油气藏地质理论；②创建了中低丰度岩性地层油气藏大面积成藏理论；③创新了系统的岩性地层油气藏勘探程序与技术系列，自主创新21项核心专利；④推动了中国陆上由勘探构造油气藏向勘探岩性地层油气藏的重大转变，使中国石油天然气股份有限公司大规模岩性地层油气藏勘探取得显著成效。图11参28

Geological theory and exploration technology for lithostratigraphic hydrocarbon reservoirs

The remaining onshore hydrocarbon resources in China,which are distributed in lithostratigraphic reservoirs of low and medium abundance,have great potential for exploration.Aimed at the exploration of the lithostratigraphic reservoirs in four types of prototype basins(onshore terrestrial rifts,depressions,forelands and marine kratons)and in glutenites,volcanics and fracture-vug carbonate rocks,significant results are achieved on geological theory,technological innovation and production efficiency through five years of systematic study.(1)Establish the geological theory about the lithostratigraphic reservoirs in the four-type basins;(2)Establish the large-area accumulation theory of low-medium abundance lithostratigraphic reservoirs;(3)Innovate systematic exploration procedures and series of technologies for the lithostratigraphic reservoirs.Twenty-one core patents are of independent innovation;(4)Push forward the significant exploration transformation from structural reservoirs to lithostratigraphic reservoirs,leading to great success in exploring large-scale lithostratigraphic reservoirs by PetroChina Company Limited.
