Hierarchical division and origin of single sand bodies in Fuyu oil layer,Fuyu Oilfield;

Sedimentary characteristics of Fuyu oil layer in Toutai area of Songliao basin;

Research on the delta deposits in Fuyu Oil Layer in east area Daqing Placanticline;

Research on the Fuyu Reservoir Sandstone Diagenesis in South of Songliao Basin——Exempled by the Fuyu and Xinli Oilfields;

Reservoir Damage in Fuyu Reservoir in Chaganhu Area of Songliao Basin

The depositional facies of Fuyu reservoir in Changchunling anticlinal zone,Daqing Oil-Field is dominated by submerged distributary channel,interdistributary bay and sheet sand micro-facies in delta front sub-facies.

Reservoir-forming mechanism of low-permeability reservoir of Fuyu Formation in southern Songliao Basin;

Using the data of the cores, thin sections, granulometric analysis and well loggings, studying in details the features about the colors of the mudstone, the texture of the rock, sedimentary structures, sedimentary rhythm and the vertical sedimentary sequences, we conclude that the main facies of Fuyu formation are lake facies and shallow water lake delta facies in Toutai area.

The major oil pay zones in this area are formed by fluvial channel sandstones within the first and second layer of the Fuyu Formation.

Division of fluvial sequence stratigraphy——an example from the Lower Cretaceous Fuyu oil-bearing layer,the Songliao Basin;

Taking Fuyu oil-bearing layer of the north slope of Fuxin dome in Jilin Oilfield as an example,the pattern recognition based on genetic artificial neural network is used to study the diagenetic reservoir facies.
