Numerical Simulation and Parameter Optimization for Integrated Water Control of Continuous Packer and Inflow Control Tool

Offshore oil fields yield substantial quantities of liquid, resulting in rapid ascent of edge and bottom water levels, as well as a swift increase in the water cut of oil wells. Consequently, an increasing number of horizontal wells are employing continuous packers and water control tools for effective water management. To accurately assess the impact of continuous packer + water control tool on both water control and enhanced oil recovery, we established a simulation method on a commercial reservoir numerical simulator. The method employs the concept of equivalent simulation to encrypt the mesh in proximity to the well, reducing its size to match that of the oil well annulus and adjusting mesh parameters for effective continuous pack simulation. By integrating this approach with an existing multi-segment well structure simulation method for water control tools, a comprehensive simulation of continuous packer + water control tool is achieved, validated through a typical reservoir model. The study further establishes the EO-MOPSO algorithm to optimize the orifice number parameter of ICD. Simulation results demonstrate that the continuous packers and ICD with differentiated orifice number parameter can achieve optimal oil recovery enhancement in the actual reservoir model.
