AICD sandcontrol screen filling and water control technology and its application
The distribution of sand bodies in a certain offshore oilfield is complex,and it is also affected by gas cap and edge water,making it impossible to fully utilize the production capacity of horizontal wells.In response to the dual requirements of sand control and water control in the oilfield,a water control completion technology using AICD water control screen tube combined with annular filling coated particles is proposed.The water control principle,pipe string design method,and filling law of AICD filling water control technology are introduced in detail.The actual production results indicate that AICD screen tube combined with film coated particle filling technology can maintain stable low water cut production status of oil wells,with significant precipitation and oil increase effects,and is suitable for reservoirs with strong heterogeneity in Bohai Oilfield.The research on the design method and filling law of the pipe string provides reference and reference for the design of water control completion in horizontal wells in offshore oilfields.
