Abstract: A computer-assisted history-matching method for geologic modeling and numerical simulation of oil reservoir was studied. The module software for perforated zone of completed wells in corner point grids was developed. The module integrates the data of well completion and oil production and tested information into the simulation models in corner point grids. The software for affecting factor analysis and computer-assisted history-matching was developed by reservoir numerical simulation technology and special knowledge. According to the main control factors, the history matching process was derived from three steps to enhance the study reliability of numerical simulation in predicting distribution of remaining oil in high water-cut oilfield. The reliable distribution of remaining oil was obtained when the module was used in the simulation study of Greater Unity Oilfield in Sudan. The adjusted development strategy based on well pattern and water injection manner was recommended.
