Abstract:

Taking usage of superposed graph can increase the petroleum exploration and exploitation effect and decrease the risk. In the petroleum exploration, through the detailed facies analysis, microfacies distribution of each layer can be mapped. When the framework reservoir sandstones are determined, superposed map of the them can be drawn and the location of good reservoir can be analyzed to drill exploration wells. While in the petroleum exploitation, through the detailed microfacies analyzing  to determine the distribution of genetic sandstone, and combining with the development data, genetic sandbodies which are not well controled by production and water injection wells can be recognized. Superposing these genetic sandbodies may tell us the location for drilling smart wells which may produce more oil and less water.

Key words: microfacies architecture, sandbody framework, superposed graph, smart well
