针对聚驱油田现场含聚油泥处理难度大、污染环境的问题,采用研制的油泥分离剂,根据热化学分离处理技术原理,按照海上平台设备的防爆要求,研制出撬装式含聚油泥处理装置,装置取得了中国船级社检验合格报告。13台(套)主设备布置在3个撬装上,设备处理能力5m3/d。平均含油14.89%~34.58%的含聚油泥经该装置处理后,污泥残油可降至0.21%~0.65%,处理完成后,上层原油回收,下层泥水研磨回注。在陆上终端厂、海上平台连续试验结果显示,装置运行稳定,处理效果良好,环保效益显著,达到了设计要求。 相似文献

查清了冀东油田废水池分布和分析了废水水质,提出了废井回灌、集中处理后回灌或回注、用废水处理机现场处理后回注或回灌等三种处理方案。通过室内、外试验论证了废水和废水池废泥治理方法,在采油所产生的含油污水实现全部回注不外排的基础上,再加上钻井废水不外排处理,从此做到了防治环境污染。 相似文献

针对油田开发过程中产生大量含油污泥处理困难的问题,文章研究将含油污泥应用于注水井调剖。重点评价阻力系数、残余阻力系数及封堵率3项物模实验指标,通过实验初步确定含油污泥颗粒粒径与储 层渗透率的匹配关系:500mD—0.02mm;1000mD—( 0.02~0.06mm);2000mD—(0.1~0.3mm),对储层 具有较好的封堵及耐冲刷性能;同时含油污泥在水驱油藏具有较好的注入性能,在地层条件下能够充分利用颗粒对孔隙结构进行封堵,含油污泥用于注水井调剖,不仅是含油污泥再利用的有效方法,也为油田综合治理、降 低生产成本提供了一项技术措施。 相似文献

I argue that many philosophical arguments for veganism underestimate what is at stake for humans who give up eating animal products. By saying all that’s at stake for humans is taste and characterizing taste in simplistic terms, they underestimate the reasonable resistance that arguments for veganism will meet. Taste, they believe, is trivial. Omnivores, particular those that I label “meaningful omnivores,” disagree. They believe that eating meat provides a more meaningful meal, though just how this works proves elusive. Meaningful omnivores could find little in the philosophical literature to help them clarify and support their position until recently. A few philosophers have argued that our culinary practices involve something more significant than taste. I categorize these arguments into three kinds. They either argue that culinary practices are a form of artistic achievement, that our diet forms part of our identity, or that a specific diet facilitates honest engagement with the world. Each of these arguments connects some aspect of our culinary practices to living a meaningful life. I examine each argument to see if it can defend the meaningful omnivore’s position. In the end, I conclude that it cannot. Nonetheless, this argument has significant implications for the animal welfare movement. Given the intense suffering caused by contemporary animal agriculture, concern for meaning is not sufficient to justify eating meat and often dairy. Concern for meaning does, however, require that we look for ways to preserve and extend culinary traditions while making them more humane. 相似文献

Environmental changes can bear upon the environmental virtues, having effects not only on the conditions of their application but also altering the concepts themselves. I argue that impending radical changes in global climate will likely precipitate significant changes in the dominate world culture of consumerism and then consider how these changes could alter the moral landscape, particularly culturally thick conceptions of the environmental virtues. According to Jonathan Lear, as the last principal chief of the Crow Nation, Plenty Coups exhibited the virtue of “radical hope,” a novel form of courage appropriate to a culture in crisis. I explore what radical hope may look like today, arguing how it should broadly affect our environmental character and that a framework for future environmental virtues will involve a diminished place for valuing naturalness as autonomy from human interference. 相似文献

对油气田建设项目进行社会影响评价可以直观有效地反映该项目带来的社会影响。文章针对四川境内已投产的4口天然气井,对其周边居民进行问卷调查,并采用了模糊综合评价法对问卷内容进行量化分析。综合得分顺序为:评价2井(0.260 87)>评价1井(0.260 86)>评价4井(0.258 93)>评价3井(0.219 34),该方法的应用可以为社会影响后评价最终结论的提出以及缓解措施的制定提供一定依据。 相似文献
