多层管柱电磁探伤测井技术 总被引:10,自引:1,他引:9
在油水井生产过程中,由于周围环境的影响,使套管发生变形、损坏和腐蚀,直接影响油田的正常生产。加强套管损坏的检测诊断,对于查明套损原因,预防套损区域扩大,确定套管的维修作业方案,延长油水井的使用寿命等方面具有十分重要的意义。多层管柱电磁探伤测井技术利用电磁感应原理实现对井下多层管柱的腐蚀、变形、裂缝及壁厚进行检测。结合从俄罗斯引进的电磁探伤测井仪,介绍多层管柱电磁探伤测井的原理方法、仪器结构及特点,井用测井资料,展示在单套管和多层管内进行套管检查的应用效果。 相似文献

由于套管受到外力、化学腐蚀等因素的作用而引起套管变形、损坏,直接影响油田油、气产量和注水效果及油、水井的使用寿命。随着各国内外油田套损井数逐年增多,套管损坏状况检查及预防已成为油田开发过程中的重点工作。工程测井技术用于检查套管井井身状况,本文介绍大庆油田工程测井技术及其在井身结构损坏检测、监测及预测中的应用情况,阐明了工程测井技术在井身结构损坏治理中的重要作用。 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
