JDY341X-110大斜度井注水封隔器的研制和应用
Development and application of injection well packer for in highly deviated well JD341X-110
摘要
Abstract
In order to solve the problems that it is difficult to load and remove packer during separated injection process and uneven force and creep deformations on rubber tube of packer in setting sealing and well washing process in highly deviated injection wells in Nanpu oilfield. By analyzing and improving the structure of conventional injection packer Y341, adopting the high temperature and high pressure resistant seal components, the improved packer could better meet the work conditions and work requirements of deviated wells and is capable of repeating setting seal. The experiments of laboratory and field showed that the packer could satisfy the demand of high temperature and high pressure injection in highly deviated wells and could realize eccentric quantitative separated injection in extended reach wells with deviation angle between SO and 70 degree.关键词
