摘要
大港某油田油泥砂处理采用热化学洗涤法,因处理时间不足及工艺参数不合理,处理效果无法达到SY/T 7301—2016《陆上石油天然气开采含油污泥资源化综合利用及污染控制技术要求》中规定含油污泥经处理后剩余固相中石油烃总量应不大于2%的要求,需要进行升级改造。通过生产情况分析和国内外处理技术调研,优选热化学洗涤与物理分离相结合的处理工艺,并根据室内试验结果,对已建空化处理撬块进行改造,并新建深度净化处理撬块,实现一级破胶破乳分离、二级空化分离、三级深度净化分离的油泥砂处理工艺,处理后的油泥砂总含油率满足小于2%的技术指标。
The oil sludge and sand treatment in Dagang Oilfield adopts thermochemical washing method.Due to the insufficient treatment time and unreasonable process parameters,the treatment effect cannot meet the latest index requirements of SY/T 7301—2016,“Comprehensive Utilization of Oily Sludge Resources and Pollution Control Technical Requirements for Onshore Oil and Gas Exploitation”Stipulates that the total amount of petroleum hydrocarbons in the remaining solid phase of the oily sludge after treatment should not exceed the requirement of 2%,so it needs to be upgraded.Based on the analysis of production situation and the investigation of domestic and foreign treatment technology,the treatment process combined thermochemical washing and physical separation is optimized.According to the indoor test results,the existing cavitation treatment skid is modified,and a new deep purification treatment skid is built to realize the oil sludge and sand treatment process of first-class gel breaking and emulsion breaking,second-class cavitation separation and third-class deep purification separation.The total oil content of the treated sludge sand meets the technical index of less than 2%.
