Evaluation On The Adaptability Of Well Completion Technology In Horizontal Well With Inflow Control Device (ICD)

Based on literature research, the adaptability of ICD well completion technology is studied in this paper with the help of Static Modeling, Fuzzy Mathematics. The working principle of ICD and the evaluation criterions of the development efficiency are analyzed. And the optimized design principles are studied from three aspects which are flow rate balance, high water cut restrain and annular flow decrease. Based on the adaptability of ICD, the structure design principle and the flow performance are presented in this paper. The influence dependents on the factors, which are variation coefficient permeability, mean permeability, reservoir thickness, anisotropy of permeability, horizontal length, pipe diameter, segmentation and ratio of pressure drop across the ICD() and pressure drop of the reservoir(). And the sensitivity analysis of these factors proceeds as well. Based on Fuzzy Mathematic, the comprehensive evaluation model of ICD adaptability is established in this paper.
