摘要：目前含聚采出水的悬淳物测定一般采用石油天然气行业标准SY/T5239一2012推荐的滤膜法。针对新疆油田七东1含聚采出水按照标准滤膜法测定易结垢问题，采用双膜法替代标准中原测定方法，过滤速率均由原来的10min过滤15mL提高到100mL以上。用不同污水对两种测试方法进行对比发现，双膜法较现行标准在测定二元驱污水和稠油污水悬淳物含量时过滤体积分别由15mL和50mL提高到了265mL和240mL，引入的最大误差由原来的26.67mg/L和8mg/L减小到了1.5mg/L和1.66mg/L。

The membrane filtration method recommended in petroleum and gas industry
Abstract:
standard SY/T5239 2012 is alweys used in determining suspend solids content in polymer flooding produced water at present. Instead of the traditional membrane filtration method, double velum method is used in polymer flooding produced water from Xinjiang oilfield sev en east 1 which has severer scaling problems.
Filtration rate is increased from 15 mL to over
100 ml during 10 min.
Experiment is conducted with polymersurfactant compound flood-
ing produced water and heavy oil sewage produced.Compared with traditionel membrane filtration method, filtration volume is more when using double velum method, The volum of polymer surfactant compound flooding produced water increases from15 mL to 265 mL and the volume of heavy oil sewage produced increases from 50 mL to 240 mL. Errors from polymer surfactant compound flooding produced water decreases from 26.67 mg/L to 1.5 mg/L, while errors from heavy oil sewage produced decreases from 8 mg/L to 1.66 mg/L Key words: polymer flooding produced water; double velum method; suspended solids; filtration: filter membrane
悬浮物含量测定方法有质量法、分光光度法遥感技术和声学法-。目前国内油田采用行业标准《碎屑岩油藏注水水质推荐指标及分析方法（SY门 5329一2012）》中的质量法来测定含聚污水中固体最浮物的含量。标准中5.2.5.4指出，对于含聚水样，需先在60℃恒温水浴中放置30min，以降低聚合物对固体景浮物测定的影响。但是新疆油田聚驱采出水在加热时会发生结垢，进而无法准确测定水中悬浮物含量。大庆油田公司李杰训等人做过相关研究，其采用的也是加热法目测定悬浮固体含
量，此方法并不适用于新疆油田加热易结垢水质。大庆油田工程有限公司的冯晓敏采用的双膜法4)（其双膜中上下双层为同一孔径的滤膜）对加快过滤速度进而增加过滤量以减小测定误差并无帮助，因此改进含聚污水中悬浮物测定方法具有非常重要的意义。
