【 摘 要 】

The slotted screen liner parameters are the same along the whole horizontal wellbore for most slotted Screen Liner completion of horizontal well, it will lead to water prematurely appears and the high water cut in high permeability area, so the research of subsection optimization for slotted screen liner parameters of horizontal well is important, which can adjust the inflow profile along the whole horizontal wellbore to enhance oil recovery, stabilize oil production and control water cut. Based on the skin factor model of slotted screen liner and the inflow control principle of horizontal wellbore, a subsection optimization model for slotted parameters of horizontal wells in heterogeneous reservoirs is established, and the subsection optimization design of horizontal well slotting parameters in heterogeneous reservoirs is realized by genetic optimization algorithm.
