Abstract: To solve the common problem of bottom water ridges in long horizontal wells for prolonging mining life and improving economic benefits, the adaptive inflow control device (AICD) was used. Based on the fluid simulation software of STARCCM+, the oil stabilization and water control performance of AICD was simulated and analyzed. The wateroil pressure drop ratio was used as indicator to measure the water control capacity of AICD. The simulation results show that when the inlet flow of AICD is constant, the wateroil pressure drop ratio is increased with the increasing of inlet number. When the inlet number of AICD is constant, the wateroil pressure drop ratio is decreased after increasing with the increasing of runner width. The optimal AICD structure is with 2 inlets, and the runner width is 0.75 mm. The wateroil pressure drop ratio of the structure can exceed 5, and the sensitivity of the structure to flow, viscosity and density is weak with strongly environmental adaptability.
