主　　题：Completion method bottom water low-permeability oil reservoir horizontal well development effect 

摘      要：The segmented water control technology for bottom water reservoirs can effectively delay the entry of bottom water and adjust the production *** clarify the impact of different methods on horizontal well production with different reservoir conditions and to provide theoretical support for the scientific selection of methods for bottom water reservoirs,a numerical simulation method is presented in this study,which is able to deal with wellbore reservoir coupling under screen tube,perforation,and ICD(Inflow Control Device)*** the geological characteristics of the bottom-water conglomerate reservoir in the Triassic Formation of the Tahe Block 9 as a test case,the three aforementioned completion methods are tested to predict the transient production *** impact of completion parameters,reservoir permeability,bottom-water energy,and individual well control on the time to encounter water in horizontal wells(during a water-free production period)is discussed.A boundary chart for the selection of completion methods is introduced *** results show that the optimized ICD completion development effect for heterogeneous reservoirs is the best,followed by optimized perforation *** is the main factor affecting the performances of completion methods,while bottom water energy and single well controlled reserves have a scarce *** average permeability of the reservoir is less than 500 mD,and ICD has the best water control *** the permeability is greater than 500 mD,the water control effect of perforation completion becomes a better option.
