为了解决海上油田高含气井电泵举升效率低、检泵周期短等难题,设计了一种适用于高含气井的新型井下气液分离器。采用多相流实验方法,分析了新型井下气液分离器在不同运行分流比、入口含气率、旋流离心加速度及倾角条件下的分离性能,并对其分离效率进行了评价。研究结果表明,在合理的运行分流比、高入口含气率、低旋流离心加速度、低倾角等条件下,新型气液分离器具有较高的分离效率,分离性能曲线形态呈现"半交叉X形状";验证了新型气液分离器具有较宽的自适应入口含气率变化能力。本文所设计的新型井下气液分离器可为海上高含气井电泵井的平稳运行提供有效的解决思路。 相似文献

分离装置的性能是评价海上平台经济水平的一个重要指标。过去20年,ICI集团公司下属的Synetix公司曾在全世界300个项目中调查其分离器的性能。所用的方法有放射性同位素和示踪剂,可在在线条件下迅速提供详细的分离器性能图像。该技术可用来评价短期的工艺条件,或永久性地固定在分离系统上用来控制流体的操作液位。文中将介绍使用方法、实例及结果。 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
