The Detailed Description Of Reservoir For Dan Oilfield Da26 Block

Dan oilfield is located in Dan a long axis anticline structure, a northern axial northwest to the long axis anticline, fractures trends and tectonic axial parallel. Main drill under the cretaceous spring in three segments in formation, bottom-up above in quantou drill, qingshankou formation, yaojia, nenjiang group, on the cretaceous sifangtai group, Mingshui group period of strata, tertiary, quaternary strata Cenozoic. Oil formations, single reservoir thickness small, reserves and oil production abundances low height is differ.According to the practical geological conditions in this region of different reservoirs in small layers of the contrast standards, fine contrast determined small layers, sure layered contrast scheme. Using core Wells of single well phase analysis, long facies sedimentary mode, then in calibration, guided by principles sequence of sedimentary microfacies section, and plane phase diagram of each small layer deposition evolution rule. Using the core material establish the different reservoirs in the logging interpretation model of each small layer of second explanation. Using the interpretation results reservoir sand body distribution, petro physical property and oil content analysis. Use stochastic modeling theory, establish the region of reservoir model structure, high attribute model. By using seismic data, tectonic interpretation and reservoir prediction, combine to produce dynamic material, launched reservoir, puts forward the comprehensive evaluation target suggestion well placement.
