随着海洋平台服役时间的延长,一些设备和管线会老化、腐蚀,须进行不同规模和形式的改造,以达到稳产、增产和节能减排的目的。管道改造在平台改造设计中尤为重要。本文以某平台改造为例,将平台管道改造设计分为出海调研、方案制定、规划出图和现场支持四个阶段,并分别对四个设计进行了分析研究,可为海洋平台管道改造设计提供参考。 相似文献

配管模块化设计在海洋平台整体模块化设计中占有较大比重。本文结合工程设计实际,以三维建模软件PDMS(工厂三维布置设计管理系统)为工具,分别从管线模块化设计方法、管线模块化设计管理、管线模块化设计注意事项和管线模块化设计对后期阶段的影响四方面进行了描述,可为海洋平台模块化设计提供参考。 相似文献

荔湾某平台调试消防泵时出现了玻璃钢管线严重振动并突然发生破裂的情况。针对这一问题,进行了理论上的分析,提出了降低水击力大小的可能措施,然后建立了消防泵及出口管线PIPENET模型,计算出了消防泵出口消防管网水击力的大小。进一步对降低水击力大小的措施进行了研究,提出了最切实可行、适合海洋平台的消防泵出口管网水击防控措施。 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
