滨里海盆地与塔里木盆地不仅同处于特提斯构造域的北缘,中新生代有着十分相似的构造和沉积发育史,而且其古生代的盆地演化、含油气性更具有可比性。它们均为克拉通内的盆地,有长期的隆坳相间构造格局,发育以海相为主的烃源岩和油气储集岩,到目前为止均发现了古生界的大油气田。通过两个盆地的对比研究,分析其同异“,他山之古,可以攻玉”,总结滨里海盆地的油气富集规律和成功的找油(气)经验,应用到塔里木盆地的油气勘探之中,可以起事半功倍的作用。 The Caspian Basin and the Tarim Basin are not only located in the northern margin of the Tethys tectonics, but also have similar structural and sedimentary histories in the Mesozoic-Cenozoic. Their Paleozoic basin evolution and hydrocarbon-bearing properties are more comparable. Both of them are cratonic basins, with long-term columbrial-facies tectonics and marine-derived hydrocarbon source rocks and oil-gas reservoir rocks. So far, large Paleozoic oil and gas fields have been discovered. Through the comparative study of the two basins, the author analyzes the similarities and differences between the two types of basins, and analyzes the laws of oil and gas enrichment in the Caspian Basin and the successful oil and gas exploration experience. The oil and gas exploration applied to the Tarim Basin Among them, can play a multiplier effect.
