Most old oil fields in Daqing placanticline have entered double development phase, trend of production rate decline can hardly be avoided. If occupies output 90% above the old oil field not to be able the stable production, our development will be an empty talk, the old oil field stable production is a key which the Chinese petroleum continues stably to develop. Therefore, increasing of the recoverable reserves realizes the need which stable center of the China crude oil output has the rise about the old oil field digs dives .But the subsurface sand bodies have had the high degree of reservoir recovery; and the distribution of oil and water has undergone the extreme change. So the main object of exploitation has turned into the thin-bed and highly dispersed oil layers from the thick. Reservoir description method and the precision which is at the Early-Middle stage have not been able to satisfy the development request of that stage by far, it fine requests, to be accurate, the quota forecasts interwell kinds of sand body interior heterogeneity.These research keys depicts and predicts to Xing 56 district from seismic inversion in north structural belt of the Daqing placanticline, discussed several kind of inversions methods principle, haracteristic, applicable conditions and existence question, those using circs analyzes and contrast, and Explores to the fine description method which to be suitable for the Daqing oilfield based on 3D seismic data, adjusts for inter welland may be a guide to seek the residual oil.
