摘要
On the basis of regional tectonic evolution and sedimentary filling characteristics, the authors carried out the research on stratum, structure, and sedimentary facies, indicated distribution law of stratum and distribution characteristics of depositional system of the Traissic System, Ordovician System and Cambrian System, also conducted spatial distribution characteristics of sand body using fine seismic interpretation, and facies-controlled sand body extension as well as reservoir prediction, and completed non-structural trap identification and predication of favorable areas.
