External casing packer
The company's business includes petroleum hydraulic disc brake, winch, top drive and other professional petroleum equipment processing and manufacturing, engineering construction services, science and technology research and development and other three main projects.
External casing packer for thermal recovery
In recently, we have investigated and analysed the problems generated when cementing and completion are absent in case of lowering screens to the oil reservoir in the horizontal well. In conclusion, well life is shortened as well workover cannot be fulfilled due to well waterflooding at the early stage, which is the main cause of well production stop. Considering such cause, we developed the R-GFY external casing packer used when cementing and completion are absent in case of lowering screens to the oil reservoir in the horizontal well. The R-GFY external casing packer can effectively prevent channelling of oil, gas and water layers, and thus lengthen the well life.
Drilling and completion tools---In-oil self-expanding external casing packer
➣ The in-oil self-expanding packer system is the packer based on the principle that rubber will be inflated in case of oil.;➣ Annular space can be closed after absorbing-cased expansion, and can be applied in open hole or casing well.;➣ It can isolate different producing formations effectively. It is not provided with moving components, requires no downhole or ground activities.;➣ The system is usually used in several completion programs, e.g. multilateral wells, horizontal well completion, intelligent completion, screen completion, and production/augmented injection.
