| The oil sludge is one of the main sources of oil field development and production process, is a complex composition, the chemical nature of the relatively stable brown sticky solid waste, which in time will not be harmful components on the surrounding environment and production equipment causing serious harm.After the preparation of pre-treatment of oily sludge into emulsified suspension profile control agent, used in injection wells profile modification, mainly refers to oily sludge by adding suspensions, dispersions, suspensions and other chemicals to form oily sludge profile modification agent system for injection wells profile modification, due to oil sludge from the formation of components, it has good compatibility, long effective period of low economic cost of notable features, not only solve the problem of environmental pollution oily sludge, and its full and effective resource utilization, increasing oil production significantly, with high economic value, compared with conventional treatment measures, economic and social benefits, a significant oil processing oil sludge is a very effective way.In this paper, oily sludge profile technology for research carried out by analysis of profile control agent of the action principle, the composition of the oil sludge fraction was analyzed, and emulsifiers, crosslinking agents, glue, etc. to promote screening determine the categories, suspension and gel formulations class profile agent system programs, and evaluate its interior and its factors: design and construction process of oil sludge site plan, the third oil extraction plant in Changqing Oilfield successfully conducted using. Further understanding of the practical application of oily sludge profile control effect on oily sludge application profile technology have a deeper understanding。... |
