Abstract

Abstract:

Along with the waterflooding development，the subsurface contradiction is becoming obvious，that is，the increase
of water production brings about decline of production. Karamay Oilfield has been carrying out waste-water reinjection since the
beginning of the development，which cause formation plugging for inferior quality，resulting in high injection pressure and low
injection rate. Based on the analysis of performance data and stemming，the plugging mechanism is studied and plug remover
is developed. The experiments of dissolved rock sample，degraded polymer and the removed iron sulfide scale indicate that
the plug remover have great dissolving capability，which can reduce the viscosity of polymer solution，oxidize and decompose
polymer gel，and remove iron sulfide scale. The FP 1 anti-swelling agent is adopted in the acidizing technology for watersensitive
sandstone reservoirs. The effectiveness of field application is remarkable，which is of certain model significance to
other similar oilfields.

Key words: waste-water reinjection, relieving damage and reducing viscosity, anti-swelling acidizing, scale removal, plugging
mechanism
