Title: Oil-gas geological features and its exploration potential in South Turgay Basin,Kazakhstan
Abstract: South Turgay Basin is an important oil-bearing basin in central south Kazakhstan,which is a rift basin of Mesozoic.The structure character is grabens separating horsts.Aryskum Trough in the south is the main depression and oil kitchen,including four NW-SE direction grabens from west to east.The oil fields found are located in the arches and slopes.The main genetic unit is Jurassic-Cretaceous series,and several regional unconformities exist through the sediments.Lower-Middle Jurassic mudstones are mainly source rocks,the principal reservoirs are the clastics of the Middle-Upper Jurassic and the Lower Cretaceous Formation,and early Cretaceous mudstone is regional seal.Although during more than 20 years exploration course,most large-size reserves have been found,there are many exploration potential fields.Except for the structure traps,the stratigraphic traps of Jurassic-Cretaceous Formations at the graben flanks and the basement weathered crust of Paleozoic are the future exploration directions.
