大孔道识别方法及聚合物微球调驱在文中油田的应用
摘要
Abstract
After long period of water flooding development,there is large channels in the injection-production process of I class of reservoirs of Wenzhong Oilfield,and therefore the low efficiency cycling becomes a outstanding problem. Large channel identifying method and polymer microsphere profile control and flooding are studied for improving injection efficiency. The large channel identifying method based on the varying law of reservoir property parameters is established because there is a corresponding relationship the varying law and logging curves and the logging curves are closely related to the large channels. The laboratory study on polymer microsphere profile control and flooding are carried out. Field application shows that,the polymer microsphere can effectively plug the large channels inthe reservoirs and reduce the difference in the permeability between layers, which realizes water-controlling and oil-stabilizing and reduces the natural decline of oil yield. The results have good application prospects to similar reservoirs in other oilfields.关键词
