我国中新生代陆相沉积岩分布面积约占我国沉积岩总面积的80％,这一特点,决定了陆相地层是我国油气勘探的主要领域,与世界上绝大部分地区的油气产自海相地层有明显不同。陆相领域以其固有的特点,勘探难度和风险都远高于海相领域。面对复杂的油气地质条件,我国油气地质勘探工作者在长期的、大量的勘探实 The distribution of Meso-Cenozoic terrestrial sedimentary rocks accounts for about 80% of the total area of ​​sedimentary rocks in China, which determines that the continental strata are the major areas for oil and gas exploration in China. Hydrocarbons from most of the world are produced from marine strata There are obvious differences. Terrestrial domain with its inherent characteristics, exploration difficulty and risk are much higher than the marine area. The face of complex geological conditions of oil and gas, China’s oil and gas exploration workers in the long-term, a lot of exploration
