THE PROSPECTS FOR OIL AND GAS, AND THE SEDIMENTARY SEQUENCES FROM TRIASSIC TO JURASSIC IN TARIM BASIN

Central Laboratory of Petroleum Geology, Ministry of Geology and Mineral Resources

摘要: 塔里木盆地三叠-侏罗系沉积可以划分为四种沉积相组合及十二种沉积亚相。木文从四个方面探讨了区内中、晚侏罗世曾发生过海水溢泛的可能性,并对三叠-侏罗系油气资源远景和勘探方向作出新的评价。

Abstract: The sedimentary sequences of Triassic-Jurassic systems in Tarim Basin can be grouped into 4 types of depositional facies and 12 types of depo-sitional subfacies. The possibility of sea-water overflowings in the area during Middle-Late Jurassic time is discussed in this poper. Thereafter, the prospects for oil and gas resources and the exploration guideline for Triassic-Jurassic sequences is suggested.
