为降低油田回收污水对污水系统出水水质的影响,针对油田回收污水直接回收到联合站污水处理系统影响回注水质和已建预处理装置处理效果不理想及运行成本较高的问题,开展了管道分离技术处理回收污水现场试验。试验结果表明:通过管道分离技术处理后的油田回收污水出水平均含油浓度、平均悬浮物固体质量浓度分别达到29.1 mg/L、76.2 mg/L,去除率分别为75.7%、41.0%;油水分离时间为310 s;与原预处理技术对比,每吨水处理成本降低52.0%。管道分离技术处理回收污水对油田开发具有重要意义。 相似文献

油田开发后期,产液中含油污水量大大增加,由于采出污水温度较低,所含的热能很难加以利用,按传统的油田生产模式,通常是采用回注的形式注入原采出地层,从而造成热资源的浪费。随着技术的不断进步和发展,利用水源热泵方式回收采出污水余热在油田受到了广泛的重视。介绍了华北油田第一采油厂吸收式热泵的应用实例,不仅有效利用采出污水热能,还可以改善工艺加热方式,是一种理想的节能途径。为油田热泵的应用提供一定的参考。 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

三江盆地绥滨坳陷白垩纪地层剥蚀厚度恢复 总被引:3,自引:1,他引:2
三江盆地绥滨坳陷地质历史时期曾经历了多期剥蚀作用,其中白垩纪至古近纪期间的剥蚀作用面积大、作用强,造成坳陷内地层大面积抬升剥蚀,地温降低,影响到油气的生成和排出.采用孔隙度法、镜质体反射率法和成熟度反演法分析绥滨坳陷南部和北部的剥蚀量,3种方法相互验证结果显示坳陷北部滨1井要比坳陷南部滨参1井经历了更大的剥蚀过程,相比之下,南部地区更有利于油气的形成和聚集. 相似文献
