油气田环境保护 第8 卷 第4 期 23 * 吴丽华 王志强 ( ) ( ) 采油生产中的油泥( 沙) 是胜利油田的重要污染源, 对含油泥( 沙) 处理国际上主要采用 加碱注热水 心分 的方法将油沙分 含油泥( 沙) 的处理在国内尚无成熟工艺目前, 主要应 采用以下方法: 原油浓度低的油泥( 沙) 和油污土壤, 主要采用微生物降解的方法进行处理; 对原油浓 度高的油泥( 沙) 和油污土壤主要采用物理化学的方法进行处理可以预测, 开展油泥( 沙) 处理及回 收利用可获得巨大的经济效益和环境效益 胜利油田 环境保护 物理化学处理 经济效益 Discuss of current oily mud/ sand condition and treating technique of Shengli Oilfield Wu Lihua ( Monitor ing S tation of Env ironment Pr otection Bur eau of Dongying City , Shang dong Pr ov ince) Wang Zhiqiang ( Gener al Env ironment M onitor ing Station of T echnique Detection Center, S heng li Olif ield ) ABSTRACT T he oily mud/ sand produced during crude production is an import ant pollut ion source in Shengli Oil ield . T he main met hod o treat ing oily mud/ sand overseas is t o separate oil and sand by means o adding alkali, inject ing hot w ater, and cent ri uging the pollut ant. T here has existed not yet matured t echnique in China to t reat oily mud/ sand. Current ly, t he main met hods used in China are microbial degradat ion met hod to treat oily mud/ sand and soil w ith low er oil concentration and physical chem ist ry method t o t reat those w ith higher oil concent rat ion . It is anticipated that the development o o ily mud/ sand processing, reclaiming and utiliz ing w ill make enormous economic and environment bene it.
