在油田生产过程中,沉降析出的罐底含油污泥的外排,由于含油污泥量大、矿化度高、含油多,对周边环境污染严重。现介绍一种新的研究成果,即将含油污泥经化学处理后变成稠化油污泥调剖剂,用于高渗透注水井调剖,封堵强吸水孔道。现场应用表明,该技术增油降水效果显著,较好地解决了污泥的污染与利用问题,为油田治理污泥污染找到一条经济有效的途径。
In the oilfield production process, the efflux of oil-bearing sludge from the bottom of the settling tank is seriously polluted by the surrounding environment due to the large amount of oily sludge, high salinity and high oil content. Now introduced a new research results, that is, the oil sludge after chemical treatment into a thickening oil sludge profile control agent for high permeability injection wells profile control, blocking strong water hole. The field application shows that the technology has remarkable effect of increasing oil and precipitation, solving the problem of sludge pollution and utilization well and finding a cost-effective way for the sludge pollution control in the oilfield.
