Hydraulic centralizer

Compared with conventional rigid centralizer, it has the following advantages:;The tool is easy to lower into wells as its outer diameter is smaller than that of any conventional centralizer.;It will not scrape the well wall during lowering, and it is especially applicable for non-conventional reservoirs.;After stretched out completely, its outer diameter is larger than any conventional centralizer. It has a strong bearing capacity, and can support the well wall effectively.

Hydraulic expandable packer
The hydraulic expandable packer (also known as the external casing packer) has a hydraulic expandable structure, and is mainly used in the cementing and completion engineering of complex oil and gas wells, so as to realize the downhole isolation and blockage for various purposes and have significant effects on improving and enhancing the cementing quality for oil/gas/water wells. Practices prove that the tool has the characteristics of easy operation and wide application, and thus it is an important cementing tool.
Stage collar
➣ It is applicable for vertical wells or the deviation wells with small deviation angles. The tool is short, and can effectively reduce bending stress. The strengths of all components meet or exceed the API standard of the corresponding casings. Shear pins are mounted at the single entrance.;➣ The potential leakage can be reduced significantly. The opening and closing pressure of the channel can be adjusted based on actual condition. There is metal-metal sealing between the body of the stage collar and the lower adapter.
Hydraulic rotation liner hanger
The rotating liner will impose dragging and carrying force on annulus fluid, leading to the spiral rising of drilling fluid and cement slurry, realizing the fully displacement of cement slurry and achieving higher displacement efficiency.
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.
In-water self-expanding packer
The in-water self-expanding packer is based on the principle that polymeric materials will expand in water. In such case, water molecules enter the polymer structure to enable the water swollen rubber to swell continuously, so as to seal the external annular space of the casing (or oil tube) and isolate horizons. Currently, this new downhole tool has been used in cementing and completion as well as in bare holes and casings.
Multifunctional bridge plug stopper
The multifunctional bridge plug stopper is the new tool that is placed in abnormal wells and special wellbores. It can provide special-shaped expansion for irregular borehole diameter and thus isolate intended zones effectively. It adopts expansion rubber tube as the sealing element, and its internal part is structured with non-continuous steel frames, providing the sealing of the concentric metal and rubber auxiliary seals at the both ends; its central pure rubber part can be used for non-concentric special-shaped wellbore sealing. It is mainly used in the completion engineering of complex oil, gas and water wells to realize multi-purpose well isolation and bridge blinding, which has significant effects on improving and upgrading the cementing and completion quality for oil, gas and water wells. This tool is important for completion by virtue of easy operation, reliable performance and strong adaptability.
