中国大陆及近岸海域居于亚欧、太平洋和印度三大板块的结合部，元古界以来形成性质截然不同的两大套沉 积岩系，经历了两期重大的构造事件，形成了东、中、西三大含油气区，造就了两类中、新生代盆地。特定的石油地质条件和勘探阶段导致目前的探明储量，层位上以中、新生界为主，区域上以东中部区为主，类型上以构造油气藏为主。根据我国盆地油气储量增长曲线呈“多峰型”的规律，近 １５ 年全国油气储量高速增长的事实，第二次全国油气资源评价结果，以及我 国的地质结构利于形成众多非构造油气藏的分析，认为中国待发现的油气资源潜力是巨大的，工作难度也很大。下一世纪上半叶，中国的油气储量和产量还将继续增长。
The Chinese mainland and the coastal areas are located in the junction of the three major plates of Asia, Europe, the Pacific Ocean and India. Since the Proterozoic, two vast sets of sedimentary rocks of quite different nature have been formed, undergoing two major structural events and forming the east, The three major oil and gas zones in the West have created two types of Meso-Cenozoic basins. The specific provenance of petroleum and the stage of exploration led to the present proven reserves, mainly in the Mesozoic and Cenozoic strata, mainly in the east-central part of the area, and mainly in the type of structural reservoirs. According to the fact that the growth pattern of oil and gas reserves in our basin shows a “multi-peak pattern”, the rapid growth of oil and gas reserves in the past 15 years, the second national oil and gas resources evaluation result and the geological structure of our country are conducive to the formation of many non-structural reservoirs , That China is to discover the potential of oil and gas resources is huge, work is also very difficult. In the first half of the next century, China’s oil and gas reserves and output will continue to grow.
