Abstract:
With the in-depth development of hydrocarbon exploration,the Mesozoic has been an important exploration object.Based on the Lithology combination,Sensitivity logging curve and 3D seismic,Mesozoic formation segment is divided and correlated,the sedimentary characteristics and strata distribution are also confirmed.Mesozoic internal structural characteristics is analyzed,the formation and evolution of tectonic pattern and the control of relic strata distribution by that are discussed.The results show that the NW and NE structural imbalance superposition controls the present tectonic pattern of Mesozoic,the relict strata thickness is thick at the syncline and is thin at the anticline.The favorable reservoir is mainly along the downthrown side of NW faults.Based on above research,hydrocarbon exploration strategy is discussed from oil source fault,oil transporting layer and trap characterization,the favorable exploration target areas are predicted.
