The Reservoir Evaluation Of The Eastern Region Shizhaihe, Zizhou Oilfield

Through the use of the study area of well logging data, drilling data andcore analysis data, made fine division and correlation of the small layer on the Chang 4+5tChang 6 reservoir, sedimentary facies and distribution of sand body, reservoir characteristics and reservoir evaluation studies, combining with the main control reservoir characteristics in the study area of Geological modeling and reserves calculation, and evaluates the reservoir, the reservoir for the final evaluation of Low abundance and low-especially low yield, the shallow, low porosity and low permeability especially small reservoir.According to the geological results of the study, to demonstrate reservoir engineering study area, develop dynamic analysis. Finalize the study area waterflooding way to determine the well network system, including meeting the ultimate recovery of the well spacing, well away from the economic limit, economically optimal well spacing and row spacing reasonably well. And analyzes the rational flow of pressure and reasonable production pressure. Finally, theoretical calculation method, test method and empirical formula of oil Comprehensive Calibration single well production capacity, and predict the final waterflood recovery.In brief,the development strategy were proved to be reasonable on the development process of Chang 4+5tChang 6,the east of Shizhaihe,it had an important contribution to enhance oil recovery.
