| Abstract: | FD96 is a particlefilling aqueous phenolformaldehyde (PhF) gelling fluid which hardens in 4.2-31.5 hrs at 60-110 and pH 9-11. It is composed of a PhF precondensate (resol), a coupling agent, a filler, a pH adjasting agent. In this paper, the composition variables, pH value, and temperature on hardening time and strength, tolerencies to salt, calcium and oil contaminations and phugging capacity for cores are investigated. The uses of this fluid for plugging intensive waterproducing zones(in oil wells) and highly permeable zones (in injection wells) and for repairing heavy leakage in casing wall at seven blocks of Zhongyuan oil fields are presented. |
