摘要: 塔里木盆地东北地区经历了发旦纪一早二叠世台地和晚二登世一中新生代陆相盆地两大沉积阶段, 发育了四套海相层、一套海陆交互相层、一套陆相含煤成油层、两套河湖相含音盐岩及第四纪堆积层。该区油气源宕丰富, 储盖层发育, 成油气期时空匹配合理, 形成海相、海法交互相和法相的多时代、多层系、多类型成油气组合, 具有优越的油气地质条件, 是我国石油、天然气工业发展最重要的接替区之一。

Abstract: The northeast region of the Tarim Basin underwent two maior sedimentary stages ; the Sinian to Early Per mian platform and the Late Permian to Mesozoic and Cenozoic terresirial oasin. There were four sets of marine formations,one paralic formation,one terresttial coal bearing formation which generates hydrocaroons, two fluviolacustrine gyp-sum bearing formations, and Quaternary accumulation. ln the region, there were plenty of source rocks, well-de-veloped caprocks and reservoits,hydtocar o0n generation siage was well natched with lrap formation. Many kinds of il andi gas reservoirs of the narine, paralie and terrestrial facies were formed. The region has good conditions of petroleun geology,and is one of the most important replacing arcas in the development of the oil and gas industry.
