【摘要】 油气田开采过程中需要配制大量压裂液用于增产,压裂液在使用过程中会产生部分不符合使用要求的余液。余液具有较高黏度以及化学需氧量,外排会对周边土壤以及水环境造成极大污染,常规方法较难处理。针对这种情况,研究了一种针对压裂液余液的处理技术,将处理后的水用于回注,减少了环境污染。更多还原

【Abstract】 Fracturing fluid is applied widely in gas and oil fields.The waste fracturing fluid which can’t meet the requirement is produced in the process.The discharge of waste fracturing fluid with high viscosity and high COD will pollute the soil and the headwaters.The processing technology of waste fracturing fluid has been proposed in this paper.The treated wastewater can be used for reinjection.更多还原
