Abstract
The research on deep profile control an d oil displacement agents for high temperature and high salini-ty reservoirs is the key for enhanced oil recovery in harsh condition reservoirs,because of the water channeling prob-lems encountered in these reservoirs. In this paper,eight deep profile control and oil displacement agents,including novel polymers,weak gels,inorganic salt precipitation,volume expansion grain,dispersed particle gel,oily sludge, flexible body and inorganic gel coat, were analyzed. Discussions on the advantages, disadvantages, profile control and oil displacement mechanism and field application of these deep profile control and oil displacement agents were conducted. At last,prospect on the research directions of the temperature resistance and salt tolerance profile con-trol and oil displacement agents was proposed.关键词
