Operation Transformation and Optimization of Wastewater Treatment System for Offshore Gas Field Production
It has been 20 years since the offshore D gas field was put into operation.With the development of the gas field entering the middle and late stage,the gas field gradually carried out pressure reduction production,sand and water were produced in some gas wells.The sand and water production of gas wells resulted in excessive water content of condensate oil exported,increased oil content of production sewage discharged to the sea,and frequent stuck faults of coalesce separator/closed discharge tank liquid level meter.According to the actual production,gas man combined with the actual situation of production,through pipe slug flow drainage speed control,improvement and optimization of production sewage treatment devices,successfully solved the problems of the production system oil emulsification material accumulation,the production sewage treatment system is ineffective and the exported condensate is not qualified,which restored the processing capacity of the production sewage treatment system and reduced the oil content of the production sewage treatment system to about 0.002 5%.
