The Indoor Optimization Experiment of Gel and Chemical Alternating Injection after Polymer Flooding
Journal Title: Saudi Journal of Biomedical Research - Year 2017, Vol 2, Issue 3
Abstract
Abstract: It is a kind of enhanced oil recovery technology with good use value and application prospect. It can obviously improve the oil recovery after flood drive. In order to investigate the effect of polymer flooding What kind of chemical agent alternately can make the best effect of flooding, the highest economic efficiency, carried out the gel and chemical agent into the indoor optimization experiment. Firstly, the effect of gelation of polymer and polymer, surfactant and binary compound system on the experiment was studied. The results showed that the gelation of the gel was similar to that of the binary composite system And the cost and economic benefits of the three chemicals were compared. The results showed that the ratio of gel to polymer was higher than that of the polymer, and the optimum pore volume was 0.35 ~ 0.5PV, to guide the scene of the remaining oil after the polymer to further tap the potential. Keywords: gel, polymer flooding, oil displacement efficiency, economic benefit.
