The Hure Field Sand West Block E <sub> 3 </ Sub> ~ 1 Reservoir Characteristics

The thesis researches the E31 clasolite reservoir bed in shaxi area of Gasikule oil field. The thesis is directed by the new theories and methods of sedimentary petrology, reservoir characterization, reservoir bed geology and reservoir bed evaluation technique. Bases on the geologic correlation and precise drill core observation of typical well, unites the slice identify, log facies study achievements, the paper makes achievements in the following aspects, first, it researches the typical sedimentary facies style and plane distribution characters of reservoir bed in aim area, builds the sedimentary facies mode of study reservoir bed; second, it systemic researches the main diagenetic events and periods, studies the cause of formation of secondly pore in reservoir bed and the main types of store void; third, it investigates the petrology characters, the physical characters and heterogeneous characters of study reservoir bed, and it studies the infection of sedimentary conditions, diagenesis and tectonic actions to the evolution of reservoir bed; fourth, bases on the above achievements, it selected six parameters which play a important role in reservoir bed evolution, evaluates and forecasts the bed synthetically used the "weighting" method, and it points out the advantageous members and the advantageous zone of the I-6 member. All of these provide the credible geological warranty to reasonable flood development at oil fields, and show the direction to the next oil exploration and exploitation.
