Taking Xianhezhuang oilfield of the Central Uplift of
Dongying Sag as an example , this paper presents the
influence of Dongying movement of Bohai Bay Basin on its
structural styles and characters of Dongying Formation by
comprehensively applying multi2information of geology ,
seismic ,drilling.Based on the sedimentary facies and seismic
facies , this paper studies the rule of distribution and
sedimentary of reservoirs and cap rocks. The effect of
structure movement and sedimentary function on the oil and
gas accumulating of Dongying Formation have been
discussed. The types of hydrocarbon and its distribution have
been confirmed. Real drilling has brought desirable economic
benefit .
