POTENTIAL OIL/GAS PROVINCES IN THE TARIM BASIN──TECTONIC WEDGES

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.
