摘要

The success of in-depth fluid diversion and enhancement of the pay zones production are hot issues in long term water flooded oilfields. However, the effect of most chemical-based water cut technologies and conformance-control treatments on fluid profile conformance are normally useful surround near wellbore zones. In addition, chemical particles can probably result in formation damage on low permeable parts of pay zone and the other potential drawbacks. Comparing to general chemical agents such as cross linker, polymer gel, foam fluid and so forth. A water shutoff plugging agent called PPG (Performed Particle Gel) show its advantage in strength-control, size-control and environment-friendly. PPG is a type of gel and synthesized with aqueous, acrylamide, cross linker and the other additives, which can be prepared at surface rather than in the wellbore, thus it is not so sensitive to high temperature and high salinity. A series of studies and field experiments through core flooding were investigated in this paper. The results indicate PPG can significantly achieve in-depth conformance in sever heterogeneous formation and can be widely applied in mature water flooded oil fields.
