Abstract

A moderate-temperature gel profile controlling agent with the modified phenol-formaldehyde resin as cross-linkage agent is studied on the basis of reservoir characteristics. The basic recipe is determined through the laboratory experimental study, and the influence of polymer, cross-linking agent, aid cross-linking agent and additive agent usage on gel viscosity are observed and studied. It made a gel profile controlling agent apply to 70 ? stratum temperature by control polymer cross-linking ratio. It has a viscosity controlled and good temperature stability. It can plugging water flow passageway effective, improving waterdrived swept wolume and exploration of oil field. [ABSTRACT FROM AUTHOR]
