Abstract
The dual-inlet channel type AICD has issues such as a single standard for evaluating water control performance,low adaptability to different types of reservoirs,and poor scientific reliability evaluation methods.By introducing the basic structure and working principle of the dual-inlet channel type AICD,analyzing reservoir types and water breakthrough patterns,a three-dimensional model and a meshed model of the dual-inlet channel type AICD are established.Numerical simulations in ANSYS are conducted on the relationship between its valve pressure drop and variations in oil phase viscosity,oil phase density,and reservoir water content;the relationship between its water control performance and flow rate is also studied.Additionally,comparative experiments are set up with the EquiFlow type AICD to analyze and compare the water control performance of both under different flow rates.The numerical simulation results show that the valve pressure drop of the dual-inlet channel type AICD is greatly influenced by oil phase viscosity and reservoir water content,and less influenced by oil phase density;at different flow rates,the maximum pressure drop of the water phase can reach 832 368 Pa,higher than the 791 366 Pa of the EquiFlow type AICD,while the maximum pressure drop of the oil phase can reach 327 648 Pa,lower than the 363 361 Pa of the EquiFlow type AICD;the pressure drop ratio can be stably maintained above 2.54,indicating good water control performance,a wide applicable range,and strong structural reliability.关键词
