Optimization model of ICD in horizontal wells coupled with the reservoir and different types ICD computation model of pressure difference were built in this paper on the basis of analyzing the flow process of fluid from layers to wellbore under the condition of well completion design with ICD in horizontal wells. And then, static simulation parameters design method and dynamic simulation parameters design methods of ICD in horizontal wells were studied, and then the characteristics, differences and operation of these two types design methods were elaborated respectively. On this basis, optimal design about ICD in horizontal wells was figured out by combining both the static and dynamic stimulated parameter design methods. The feasibility and applicability of model and optimal design method of well completion with ICD in horizontal wells were verified by example calculation and analysis. These study results provide some theoretical basis for optimal design about ICD of horizontal wells.
