| The purpose of this research is to study the reservoir performance and static state in Huangjindai field comprehensively by using multiple technologies and multidisciplinary theory and methods,with further gaining clear idea of all kinds of properties of geology and development and refinement,building the reliable reservoir geological model and regularities of distribution of remaining oil and knowing the potential of production,the optimal scheme for reservoir development and adjustment will be provided.Aiming at the major reservoir,Shahejie group is subdivided based on the original division of sandstone beds.The Sha-1 section has been divided into 3(up,middle,down)subsections,including 15 sandstone beds and 33 substrata.Sha-3 section has been divided into 3 reservoir sets,including 19 substrata and the strata from Huangjindai Dongying team to Sha-3 section has been divided into 33 units.Based on the study on sedimentary characteristics of work area which integrated all the regional geological information,core and well logging data.We build the sedimentary facies model and reveal the spacial distribution rule of sedimentary microfaies in Research area.Start the"four properties"relationships research on reservoir,establish the geological reservoir parameter logging interpretation model which is restricted by geology condition and set the new effective thickness standard as well as reservoir single well parameter base.The study has found that the main reservoir type in Huangjindai is lithology-structural reservoir.The dual factors,structure and lithology determine the distribution of oil/gas/water.Sedimental environment,structural factors cause the different development degree of oil/gas in this area.All levels of fault and ties of matter affect the distribution in plane and longitudinal direction in difference.We built the geological models of strata,sediment and reservoir parameter and a set of 3-D data body model. |
