适用于注水井的大通径分层封隔器集成化设计

Integrated design of large-diameter isolation packer for water injection well

渤海油田进入了开发中后期,稳产、增效成为油田开发重要方向,对于地层压力衰减严重的井常用注水手段实现产量提升或稳产,目前注水工具受限于防砂管柱内通径尺寸限制,导致注水工具无法增加注水工具尺寸,提升注水排量受限,所以研发适用于注水井的大通径防砂工具意义重大。

The Bohai Oilfield has entered the middle and late stages of development,and stable production and efficiency have become important directions for oilfield development.Water injection methods commonly used for wells with severe formation pressure attenuation have been used to increase production or stabilize production.At present,water injection tools are limited by the size of the sand control pipe.Water injection tools can not increase the size of water injection tools and increase the water injection displacement.Therefore,it is of great significance to develop a large-diameter sand control tool suitable for the current water injection.
