Study On The Qualitative Identified Explaination System Of The Flooded Layers Of Fuyang Reservoir In Yushulin Oilfield

The Fuyang reservoir of Yushulin oil field is a typical of low permeability reservoir. The sand distribution of Fuyang reservoir of Yushulin oil field is complex, the physical properties of sand body have changed greatly, and the heterogeneity of sand body is very characteristic, some blocks or reservoirs have shown in various flooding conditions. Therefore, in order to improve the benefit in the oil-field development, the study on the system of water flooded layer qualitative identification interpretation is imperative.Firstly, this thesis analyzes the geologic condition of Fuyang reservoir of Yushulin oil field, collectes and investigates the regional basic material deeply. Secondly, by using the preliminary prospecting material evaluating exploratory shaft and formation testing in Yushulin oil field, this thesis analyzes the oil-water distributing regularities on the original reservoir and the relative logging response, establishes the original oil-water relationship chart of reservoir and completes the logging response distribution comparison among the later infilled wells and the primary reservoir. Thirdly, based on the water flooding mechanism research of the FuYang reservoir of Yushulin oil field and the logging response characteristics of the water flooded layer, this thesis establishes the identification intersection chart of the water flooded layer of Yushulin oil field, and sets the qualitative identification standard of the water flooded layer of Fuyang reservoir of Yushulin oil field by the way of mode differentiating. Finally, this thesis programmes the interpretation software of the water flooded layer of Yushulin oil field and formes the relative qualitative identification interpretation system by using Delphi and Access.By using the completed original reservoir recognition chart and water flooded layer qualitative identification standard, and the discrimination of water flooded layer interpretation software, this thesis schemes the layer-perforating project of 51 infilled wells in the 16th eastern block established in 2009. As proved in the development outcome, the system shows the coincidence rate of more than 75%, and the methods we studied in the thesis can be widely used in the peripheral water flooded layer identification.
