【摘要】：当前,我国绝大部分油田都已进入特高含水开发期,提高常规沉降分离设备的处理效率、研发和应用低成本的油水分离技术成为亟待解决的问题。粗粒化油水分离技术是通过在油水分离器中装入聚结填料来提高油水分离效率的采出液处理方法,其因操作简单方便、投资成本低且无二次污染等优点越来越受到研究人员关注。本文针对目前粗粒化油水分离技术的主要难点既聚结填料的优选进行了实验研究。首先依据聚结机理通过接触角测量实验从众多聚结材料中优选出不锈钢材质作为填料材质。进而通过调研及液体在填料中的流动形态模拟计算优选出波纹板作为填料基本空间构型。在材料优选及初步空间构型优选的基础上,应用小型油水分离器进行室内试验,从理论计算与实际分离实验两方面综合对比CY250及CY350两种不锈钢波纹板填料的油水分离效率。从采出液含油量、油滴粒径分布、进液流量、填料比表面积、板组长度等多个方面进行比较分析研究影响聚结分离效果的因素并优选出CY350为最优粗粒化油水分离器填料。CY350具有最优化的比表面积,对于水相流动阻力较小,不仅油水分离效果好,且使用刚度和耐用度更高,不易损坏、便于安装和管理。
[Abstract]:At present, most of the oil fields in our country have entered a highly high water cut development period. It is an urgent problem to improve the processing efficiency of conventional sedimentation separation equipment and to develop and apply low cost oil and water separation technology. The crude oil and water separation technology is the extraction liquid which can improve the oil and water separation efficiency by loading the coalescing packing in the oil-water separator. With the advantages of simple and convenient operation, low investment cost and no two pollution, this paper is concerned with the main difficulties of coarse grained oil and water separation technology, which is the main difficulty of the main difficulty of coalescence packing. The stainless steel material is selected as the filler material. Then the corrugated plate is selected as the basic space configuration of the packing through the investigation and the flow pattern simulation of the liquid in the filler. On the basis of the selection of material and the initial space configuration optimization, the small oil water separator is applied for laboratory testing, and the two parties are calculated from the theory and the actual separation experiment. The oil and water separation efficiency of two kinds of stainless steel corrugated plate packing with CY250 and CY350 is compared. The factors affecting the coalescence separation effect are compared and analyzed from the oil content of the produced liquid, the distribution of oil droplets, the flow flow, the surface area of the packing, the length of the plate group and so on, and the optimization of the CY350 as the packing.CY350 of the optimal coarse grained oil-water separator is made. With the optimal specific surface area, the resistance to water flow is smaller, not only the oil water separation effect is good, but also the use of stiffness and durability is higher, it is not easy to damage, easy to install and manage.
