To study oilgas distribution law of the lower generation and upper accumulation source rockreservoircaprock pattern in oilgasbearing basin,based on the study of condition and mechanism of oilgas migration along fault or along sandbodies on both sides with lateral division migration,by comparing the relative size of the displacement pressure in fault filler and sandbodies on both sides,this study discussed a set of judging method of oilgas migration along fault or along sandbodies on both sides with lateral division migration,and applied it to the discrimination of whether oilgas migrates along 7 faults or along 62 sand layers on both sides with lateral diversion migration in Dongying Formation of 5 Nanpu Depression typical blocks.The result indicated that,in 62 sand layers of Dongying Formation,the displacement pressure of 43 sand layers was less than that of fault filler,oilgas migrated into sand layers with lateral diversion migration;the displacement pressure of 19 sand layers was larger than that of fault filler,so oilgas migrated upward along fault,which was coincident with current result of oilgas drilling revealing the distribution of oilgas.It indicates that the method is feasible to be applied in discrimination of whether oilgas migrated upward along faults or along sandbodies on both sides with lateral division migration.
