Abstract: The risks for development of high water-cut reservoirs in horizontal well were analyzed.The numerical simulation of watered-out mechanism in horizontal well was carried out.The basic models for describing the distribution of remaining oil in the well pattern of the injector-producer rows were established.The factors affecting the development behavior and production performance of horizontal well,such as reservoir scale,reservoir properties,fluid properties,parameters of horizontal segment,liquid rate and the distribution of interbeds were discussed.Sixty six cases and their sensitivity analysis projects were designed.The relative sensitivity of each factor to the production performance of horizontal well was investigated synthetically.

Key words: high water-cut reservoir, horizontal well, watered-out mechanism, numerical simulation, risk analysis, sensitivity analysis
