Abstract:
In order to study controlling of “sourcerockfaultspotential energy” to reservoir models in Beier depression,we superimpose the reservoir distribution,sourcerock,faults and potential energy,and draw that: 1)Formation and distribution of oilreservoir are controlled by area of K1n1 sourcerock. 2)Area of low potential energy controls the place oil accumulated; low potential energy areas of inversion faults tilting uplifts controls oil accumulation in K1n and K1t.Low potential energy areas of inversion tectonic controls oil accumulation in K1d,low potential energy areas of ancient uplifts controls oil accumulation in bedrock hill. 3)Faults control oil migration outside sourcerock,as longperiod faults control oil generated from sourcerock of K1n1 migrates to K1d and early extending faults control oil from sourcerock of K1n1 migrates to bedrock.The conclusion is reasonable spatial matching of “sourcerockfaultspotential energy” controls oil accumulation and distribution in Beier depression,but different layers have different characteristics.in K1n group and K1t group,that appear in reversion fault tilting uplift and sags in uplifts,in K1d group that is represented on inversion tectonic while in bedrock,that is showed on paleouplifts.
