POTENTIAL OIL/GAS PROVINCES IN THE TARIM BASIN──TECTONIC WEDGES
-
摘要: 塔里木盆地内部,受不同地质年代的造山(形变)作用影响,在毗邻烃源岩区正向单元(构造褶皱隆起)一侧或两侧的斜坡地带上所形成的“构造楔”将成为油气运聚圈闭成藏的场所。当它们有良好的储集与封盖条件,可望成为塔里木盆地今后油气勘查并实现突破的新领域。Abstract: In the interior of the Tarim Basin, due to the influences of orogeneses (deformation)in different geologic ages,tectonic wedges occurred in the anticline zones, on one or both sides of a normal unit (tectonic fold-uplift) adjacent to the areas of hydrocarbon source rocks.These wedges will become the places for the migration,accumulation,trap and pool of oil and gas.It is expected that they will be nowdomains in the Tarim Basin where future oil/gas survey and exploration,moreover the realisation of a break-through can be based,when there are favourable reservoir,sealing and capping conditions.
