【摘要】：在水驱和聚合物驱过程中,沉降析出在罐底的含油污泥处理和利用一直是国内油田亟待解决的技术难题。据初步统计,大庆油田在油水分离过程中每年会产生数万方含油污泥。由于含油污泥内不仅含有油和黏土,而且还含有多种有害化学物质,随意排放会对周围环境尤其是地表水源造成严重污染。随着油田含水的不断升高,污泥排放量也将不断增加。同时,随着人们环保意识的加强和国家环保法令法规的不断健全,污泥无害化处理愈来愈受到人们的重视,已成为各油田重点研究的课题。本文分析了污泥采集与组成分析及污泥聚合物溶液组成,设计了泥土颗粒岩心流动性能实验,对污泥聚合物溶液调驱效果,污泥聚合物溶液传输和转向能力进行研究,后进行了含油污泥调剖施工与并分析其效果。
[Abstract]:In the process of water flooding and polymer flooding, the treatment and utilization of oily sludge precipitated at the bottom of the tank has always been a technical problem to be solved urgently in domestic oilfields. In Daqing Oilfield, tens of thousands of oily sludge are produced every year in the process of oil-water separation. Because the oily sludge contains not only oil and clay, but also a variety of harmful chemicals. Random discharge will cause serious pollution to the surrounding environment, especially to surface water sources. With the increasing water content in oil fields, sludge discharge will also continue to increase. At the same time, with the strengthening of people's environmental protection awareness and the continuous improvement of national environmental protection laws and regulations, More and more attention has been paid to the harmless treatment of sludge, which has become an important research topic in various oilfields. In this paper, the collection and composition of sludge and the composition of polymer solution of sludge are analyzed, and the experiment on the fluidity of soil granular core is designed. The effect of sludge polymer solution flooding control, sludge polymer solution transfer and steering ability were studied. After that, the profile control of oily sludge was carried out and its effect was analyzed.
