Oil And Water Distribution And Prediction Of Favorable Development Block Of Fuyu Oil Layer’s In South Zhaoyuan Area

The south of Zhao Yuan area is mainly block The oil product no.10 of Daqing production potential, to study the Fuyu reservoir and oil distribution and its main controlling factors, is the key to the evaluation of block production potential. This paper based on the theory of sequence stratigraphy, on the characteristics of the strata in this area for detailed study; the deep lateral resistivity, spontaneous potential logging curve analysis principle of contrast and oil testing data, oil, gas and water were established criteria, discusses the distribution of the oil, gas and water; using 3D seismic technology, the fracture characteristics of the study area are fine description; through to the migration and accumulation of oil and gas accumulation reservoir model research, master the the main controlling factors of reservoir. Mode is on the plane of the longitudinal research thinks, oil, gas and water in the plane distribution is strictly controlled by the faults control the oil, gas and water distribution is controlled by fault and gravity differentiation principle of common control; oil and gas mainly comes from Sanzhao sag, oil and gas secondary migration of oil and gas along the fault sand body fault migration path in sections along the fault sand body fault ladder path climbing type migration; the study area to oil and gas accumulation in the main control factors: fault and river sand body are matched to form oil and gas migration channel system migration is the premise, structure, fault and sand body effective matching to form an effective trap, trap is the key. On this basis, the evaluation method of the effective thickness of reservoir, fault development zone and productivity can be evaluated in the four favorable exploration blocks.
