| Abstract: | A delayed crosslinking HPAM/Cr3 aqueous system is developed for indepth profile modification (injection water flow diverting) in Zhongyuan Oil Fields. This system becomes from solution to gel in 310 days at 60120 owing to using a chromorganic crosslinker, HY1, and a delay agent in combination. This paper presents the selection of proper component concentrations, the effects of pH, temperature, minerality and shearing on gelation and on gel viscosity, and the gel stability. |
