Abstract
In the light of the challenges predicting the production performances at the exploration and development appraisal stages,the novel idea and methodology were presented to conduct the rapid production performance prediction based on the digital reservoir analog knowledge.The forecast process integrates the statistical analysis,dynamic attribute simulation and decline curve analysis,and moreover the analytical predicting tool was developed under the condition of the website.The process stated above needs the help of the global digitalized reservoir analog knowledge database,analog sample selection,analog statistic analysis,dynamic prediction and development strategy analog.Taking the fractured carbonate reservoir in Oilfield A at its development appraisal stage as example,the predicted results provide the production rate,water cut,duration time and final recovery factor at different developed stages,and furthermore derivable the indexes such as the water-oil ratio,produced degree and so on.Comparing the development performances and predicted results with the similar-reservoir-characteristic matured Oilfield A,the viability and feasibility of the method was further verified.On the basis of the digitalized IOR/EOR analog analysis,the development strategy concept was further put forward.关键词
