The Experimental Research on Combining Binary Compound Flooding and Profile Control Technology to Improve Recovery Efficiency

Abstract:

With the using of binary compound flooding in Jinzhou oil production plant of Liaohe Oilfield, problems like interwell interporosity flow and the unsatisfactory displacement effect occurs. The EOR method of combination of binary compound flooding and profile control technology has been adopted to solve these problems. The JSY crosslinking agent has been selected which has good compatibility with binary compound system by means of experiment of gel strength and gel time. And the formula system of binary compound flooding profile control which can improve the displacement effect of Jinzhou oil production plant has been formed after concentration optimization aim at improving oil recovery. The laboratory core plugging experiments show that the system of binary compound flooding profile control behaves better plugging effect and its plugging rate was greater than 94%. The parallel displacement experiments on low, medium and high permeability cores show that the oil recovery of binary compound flooding profile control system, which can improve the oil recovery more effectively, enhanced about 12% of oil recovery than binary compound flooding.
