1 Geological Characteristics of the Reservoir Reservoir Pu’nan Oilfield is located in the southward extension of the Putaohua structure of the Daqing Changyuan Basin in the central depression area of the Songliao Basin. Its two wings have a dip angle of 2 to 3 °, with the whole area showing high in the middle and low on both sides. The average depth of the oil field 1860m, from top to bottom development of three sets of oil system, that is, Black Temple, grape and Fuyu reservoir, the reservoir basic conditions are as follows: Reservoir Depth Pressure coefficient Bursting pressure gradient Average effective hole
