Formation condition and distribution rule of multiple type oil pools of Satellite oilfield in the northern part of Songliao Basin

Besides Putaohua reservoir of Daqing Placanticline in the northern part of Songliao Basin,Satellite Oilfield,rich in reserves and high in single well oil production,is the largest oilfield.Through analyzing the exploration wells and the production wells in the oilfield,oil generation condition,shape and evolution history of its structures and fractures,sedimentation facies distribution,reservoir characteristic and oil,water distribution characteristic in every development area are systematically studied.And the oil,water distribution rule,reservoir type and the reservoir forming controlling factor are also analyzed. Different deployment of structure,fault and sandbody of the Satellite Oilfield forms all types of reservoirs, dominated by fault-structural oil reservoirs,fault-lithology and lithologic reservoirs are subsidiary.It is also pointed out that Taidong area, south to the Satellite Oilfield,having the like reservoir forming condition,is the important area of next exploration study and deployment.
