摘　　要：裸眼水平井相对于传统的井型在增加储层接触面积、提高采收率和降低生产风险方面具有较大的优势,是一种相对来说经济效益较高的井型。通过对6.5寸裸眼水平井进行砾石充填时施工参数选择过程,并将理论分析和实践施工数据相结合,为其他尺寸井型选择合适的防砂工具组合以及砾石充填防砂技术提供思路,以供相关从业人员和设计者参考。In summary,compared with traditional Wells,open-hole Horizontal Wells Have greater advantages in increasing reservoir contact area,improving recovery efficiency and reducing production risk,and are relatively High economic benefits.many reservoirs in Bohai oilfield Have typical characteristics of thin layer,which is especially suitable for development and production by open Hole Horizontal Wells.Therefore,open-hole Horizontal Wells are widely used in Bohai oilfield.not only that,the supporting gravel pack sand control technology Has also been quite mature,after years of practice,whether from sand control down-hole tools,surface sand control equipment,from sand control design simulation software and other aspects Have been widely used,the annual operation volume is maintained at about 200 Wells.In recent years,with the need of development and production,the Hole size of open Hole Has changed,and the size of sand control tool Has also changed.When different wellbore structures and string combinations are used for packing design,the traditional gravel packing sand control construction parameters need to be optimized accordingly,otherwise,it is easy to Have irreversible adverse effects such as low filling efficiency and poor sand control effect.This paper aims to provide ideas for gravel packing and sand control by combining theoretical analysis and practical construction data through the selection process of construction parameters for gravel packing in 6.5 inch open Hole Horizontal Wells,so as to provide reference for relevant practitioners and designers.
