在稠油开采过程中,存在缺少大吨位锅炉配套水处理装置,且小型水处理装置不能满足区域多台小吨位注汽锅炉供水需求的问题。针对生产现场的实际需求,研制了50 t/h水处理装置,该装置能为大吨位注汽锅炉提供锅炉用水,而且采用智能等量水分配装置,可同时为多台小吨位注汽锅炉供水。该装置水处理采用两级逆流再生离子交换设备,能有效去除水中的有害离子和溶解氧,实现水质的自动检测、报警;采用水质闭环自动控制、再生流程开环自动控制,实现锅炉水质的自动处理;还可作为锅炉储备水源,解决燃煤注汽锅炉停电所带来的爆管危险。该装置具有自动化程度高、占地面积小、运行速度快、出水水质稳定、耐腐蚀能力强、使用寿命长等特点,完全可满足油田水质需求,具有很高的行业推广价值。 相似文献

针对海上某油田注入水长期不达标的问题,在生产水水质分析与认识的基础上,结合平台具体条件,制定了紧凑型旋流溶气气浮(CDFU)+两级精细过滤,并辅以水处理药剂的小型化水质改善工艺。CDFU具有结构简单、占地面积小、摆放灵活、抗波动性强等特点,可有效克服平台空间限制、来水波动大的难题;高效水处理药剂能够解决生产水中高含量H_2S导致的水质发黑问题。该工艺在现场应用中取得良好效果,出水水质平均ρ(油)4.25mg/L,平均ρ(悬浮物)0.45mg/L,平均粒径中值1.35μm,满足A2回注水指标要求,工艺可行性得到验证。该小型化水质改善技术的试验成功对于海上油田含硫生产水处理具有重要的借鉴意义。 相似文献

河南油田在稠油污水处理过程中,由于含油污水输液量波动大、含油密度大、胶质和沥青含量高,使得污水处理后水质达不到要求。为此提出了控制油珠粒径、控制油水密度、粘度及加药等具体措施,并设计出了新的处理工艺流程。污水处理工艺改造后,处理水质最终含油量小于10mL/L,机械杂质含量小于5mg/L,达到了注水水质要求。 相似文献

海水淡化处理装置在海上油田热采中的应用 总被引:1,自引:0,他引:1
海上油田热采对水质要求严格,海水不能直接作为热采用水;海水资源丰富,取材方便,但常规水处理设备无法处理,陆地用海水淡化装置又由于体积大无法安装在海洋平台上。文章介绍了中海油田服务股份有限公司专门研制的海水淡化处理装置的主要设备、工艺流程、运行参数及处理效果,并对其经济效益进行了对比分析。该装置结构紧凑,占地面积小,适合在海洋平台上安装使用;产水量达到20 m3/h;处理后的产出水总硬度为0.2 mg/L,总碱度为20.80 mg/L,悬浮物含量小于1 mg/L,产出水水质满足多元热流体热采对水质的要求。 相似文献

双滤料过滤器在污水处理系统中的应用 总被引:2,自引:1,他引:1
针对低渗透油田回注污水水质不达标的问题 ,采用GLWA30 0 /0 6(S)型双滤料全自动过滤器 ,以改造纯化油田污水处理系统。介绍了过滤器的结构、工作原理和主要技术参数 ,并与石英砂过滤罐进行了比较 ,认为双滤料自动过滤器具有过流量大、滤料再生能力强的特点 ,经过多个周期反冲洗后 ,可形成滤料粒径自上而下由大到小的反粒度滤层 ,提高了过滤水的穿透能力 ,最大限度地发挥了不同密度、不同级配指标下滤层的截污能力。通过污水处理前后水质指标的对比 ,说明这种过滤器可有效地减少大修井及作业次数 ,年经济效益达 633万元 ,且减少了地下的环境污染 相似文献

采油过程中,酸化是油气井增产、注水井增注的主要措施。砂岩基质酸化和碳酸岩基质酸化都是在低于储层破裂压力的条件下向地层中注入酸液,溶解地层中的可溶物质,清除孔隙或裂缝中的堵塞物质,从而使油气井增产或注水井增注的一种工艺措施。本文着重讨论了砂岩酸化的设计计算方法,并由此建立一套基质酸化设计方法。 相似文献

《Oil and Energy Trends》2008,33(5):6-7
This section summarizes downstream developments of the previous month. Exploration & Production are covered in 'Upstream Review'.
An upsurge of violence in Iraq threatened a recovery in output that began earlier this year. Production in the northern fields hit a post-invasion high of 620,000 bpd in March, rising by 180,000 bpd in one month. Fighting in the south, however, cut production there by more than 100,000 bpd as government troops tried to subdue Shi'ite militias in and around Basrah. Oil installations damaged in the south included a pipeline and a pumping station. The Iraqi government nevertheless announced that oil production would reach 2.9 mn bpd by the year's end, requiring an increase of nearly 500,000 bpd over April 2008 levels. Foreign help is to be sought via a series of technical service agreements and - later this year - an upstream licensing round. Japan's Ministry of Economy, Trade and Industry says it wants a bigger role for Japanese oil companies in both the upstream and downstream sectors in Iraq. Kurdistan says it is negotiating with Baghdad to export oil produced from new oil fields there. The central government does not recognize production agreements drawn up by the Kurdistan Regional Government. The EU - desperate for gas to fill its Nabucco pipeline - has approached Iraq for up to 1 bn cfd. 相似文献
