Reservoir Characterization Of Complicated Small Fault-block In Continental Rift-Subsidence Basin

China has maximum distributing of continental petroliferous basin in the world,and is a petroleum-prodution country mainly possess terrestrial petroliferous basin.Almost clastic rocks in all kinds of sediment environments can receive oil and gasbecome oil and gas reservoir, on the influence of sediment supply and structure,especially fault, exploration in continental rift-subsidnce basin about oil and gasbecome more and more come complex, so there are some questions need to resolveforwardly, and with the increace of need about oil and gas, we find oil and gas fromcomplicated small fault-block in continental rift-subsidence basin becomenecessary.With the development of all kinds of technique measure and method, reservoirhold the balance station in oil and gas exploration, and the foundation ofquantificational 3D space reservoir geology model is the need for oil and gas inexploration and exploitation, by using of all kinds of data, for example drilling data,logging data and seism data, and is embodiment of reservoir study for high phasedevelopment.On the base of above-mentioned causes, combine the oil and gas' breakthroughin Beihangzhuang field and imperfection about fundamental study, in order to reachfurthermore exploration and exploitation effect, the paper use all kinds of data toprocess fundamental study firstly, on the basis of logging data reinterpretation andreservoir sediment microfacies, develop reservoir inversion prediction under wellrestrict. According to pick up seismic attributes, draft the relationship betweenreservoir characteristic and seismic attributes, and reach the aim about reservoirprediction with seismic data. Discussed the structure develepment process ofBeihangzhuang field between FuNing formation and SanDuo formation sediment, at last, accomplished reservoir simulation about Beihangzhuang field from structure,sediment facies, porosity and permeability in 3D space.Due to the complexity of complicated small fault-block in continentalrift-subsidence basin, wei use fault forward model and coherence technique discusssmall fault interpretation, and I believe it will redound to exploration of oil and gasin congeneric prospect field.
