Changchun Ridge southern Songliao Basin oil and gas fields located in the northwestern edge of the Southeast Uplift and help uplift the northeastern edge of the new site, an area of ??151km ~ 2, is the southern Songliao Basin newly discovered oil and gas rich one large oil and gas fields. In this paper, the study area reservoir geology and difficult problems to sedimentology, structural geology, geophysics and petroleum geology of theoretical guidance, integrated geological, drilling, logging, seismic and oil testing, production test, etc., using multi-disciplinary, multi-technology combines comprehensive research approach to Fuyu reservoir as the research object, to construct, depositional environment, reservoir distribution, reservoir law with a focus for fine reservoir description geological evaluation study on the southern Songliao Basin Changchun Ridge conducted Fuyu oilfield reservoir description. Detailed study of Changchun Ridge oilfield Fuyu reservoir structure, sedimentary, reservoir and reservoir characteristics, oil and gas reserves are calculated for increasing reserves and production and oilfield exploration and development to provide a reliable geological basis. Through research, the results of this paper made the following points: 1. Using full three-dimensional fine structure interpretation technique, refined oil and gas fields to implement the Changchun Ridge Fuyu oil layer forms on top or bottom, revealing the pattern of the area showing the overall structure of the long axis of the north-trending anticline the situation in the North East, EW, nearly NS and NNE-trending faults together, Fuyu oil layer structure becomes more broken, partial structural form is rendered as multiple faults together to form a series of block and broken nose. (2) In this paper, sedimentary facies analysis and reservoir inversion forecasting techniques Fuyu oilfield Changchun Ridge Reservoir sedimentary characteristics and distribution characteristics are described in detail, revealing the Fuyu oil layer mainly developed delta front facies. Provenance mainly from the work area southwest of the main types of sand delta front subaqueous distributary channel sand body, mouth bar and sheet sand sand sand, reservoir distribution vertical and lateral changes rapidly. 3, in the reservoir characteristics and hydrocarbon reservoir characteristics and other aspects of the basis for the calculation of reserves that are shallow Changchun Ridge oilfield, the middle, in abundance, with a hundred million tons of reserves, a large reservoir. 4, through field studies evaluating Changchunling established southern Songliao Basin fluvial sandstone reservoir description technology and promote the Shonan Fuyu super shallow reservoirs are developed to achieve the region's oil and gas production replacement strategy.
