喇嘛甸油田产能区块已转入以高浓度聚合物驱为主的开发方式。高含聚期采出液已成为一种复杂的注聚含油污水体系,采出液的性质的改变,导致沉降罐易形成老化油,过滤罐内部滤料板结,过滤水质不达标等现象产生,现有的污水处理工艺很难满足高含聚污水处理要求。污水站地面系统工艺优化采用的主要工艺技术有沉降罐连续收油,滤罐内部改造,变频反冲洗及静压排泥工艺,应用后污水站处理水质达标,提高了污水处理系统整体适应性。
Lamadian oilfield production block has been transferred to high-concentration polymer flooding-based development. High content of poly-phase recovery of liquid has become a complex injection of oil-contaminated water system, the nature of the production fluid changes, resulting in the formation of aging tank easy to aging oil, filter tank within the filter board junction, filter water quality standards and other phenomena, the existing Of the sewage treatment process is difficult to meet the requirements of high poly-containing sewage treatment. Sewage station ground system technology optimization of the main process technology used for settling tank continuous oil collection, internal transformation of the canister, frequency counter-flushing and static pressure sludge discharge process, after the application of sewage treatment station water quality standards to improve the overall adaptability of sewage treatment system.
