- Abstract
In order to solve the problem that the pollution causes and the degree of the injection well can not be effectively identified, based on the consideration of the sensitivity of the reservoir and the water quality of injected water. The mathematical models of injection well pollution were established. The causes of pollution and pollution degree were determined.Recommended measures to different factors of pollution are confirmed. It proved that the efficiency of the recommended measures has been greatly improved. Research results show that,according to the degree of pollution to all factors of pollution, the rank from largest to smallest is solid particle, clay swelling, water sensitivity, inorganic scale, acid sensitivity, bacteria, particle migration, velocity sensitivity. Therefore, the major factors of pollution in the reservoir are solid particle and clay swelling.
