An offshore platform is a water injection development oil field,and most of them are high water cut oil Wells.With the implementation of production improvement measures such as adjusting well operations and changing large pumps,the production water treatment capacity increases year by year.As the last stage equipment in water treatment,walnut shell filter plays an important role in water quality standards.However,recently,more walnut shell filter material was found in the process of downswimming water system treatment,which will continue to make the filter material leakage more serious,resulting in some oil and suspended solids adsorbed on the surface of the walnut shell ability to reduce,walnut shell backwashing frequency increase,filter material leakage vicious cycle,shorten the walnut shell replacement cycle.In response to this problem,on-site investigation,analysis of the reasons and test demonstration,by optimizing the walnut shell backwashing flow and backwashing strength,the walnut shell filter material leakage control in a reasonable range,effectively control the walnut shell filter material leakage,the treatment effect has been significantly improved,improve the regeneration capacity,greatly reduce the labor time and material consumption.
