本文从两个方面阐述了工程测井技术在油田开发中有关套管损坏方面的应用。一方面应用工程测井技术检测套管损坏状况,为套管损坏井修井怍业提供直观的资料及为修井质量检查提供依据,也为套管严重损坏井报废作业提供详实可靠的资料;另一方面应用工程测井技术为套管损坏成因分析和制定预防方案提供资料。经研究工程测井技术既可有效地检测套管损坏状况,又可为套损预防提供可靠的资料,指导修井作业、检查修井效果、报废并取证和决策中发挥重要作用.其次开展有针对性的工程测井将有利于套损分析和预防方案的制定。 相似文献

套管损坏将直接影响油水井的使用寿命及油气产量,而电磁探伤测井技术可对井身结构作“体检”。结合江苏油田应用情况,介绍了可过油管检查套管损坏的电磁探伤测井仪的工作原理、结构、功能等特点。对及时发现井身结构变形、损坏,对于检测油管、套管使用状况、套管结垢、指导修井、预测套管使用寿命起重要作用。 相似文献

套管由于受到外力、化学腐蚀等因素的作用而引起套管变形、损坏,直接影响油、水井的使用寿命,进而影响油、气产量和注水效果。随着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。文章阐述俄罗斯电磁探伤测井仪EMDS—TM-42E型伽玛一电磁探伤检测仪的工作原理、结构及功能特点,分析电磁探伤测井在江苏油田多口井中的现场应用情况,认为电磁探伤测井作为一种可为油、水井井身结构做“体检”的方法,对及时发现井身结构的变形,修复套损发挥了积极的作用。 相似文献

随着吉林油田勘探开发的不断深入,开采年限的不断增长,部分地区由于长期注水开发,加之频繁的措施作业及井身结构、完井固井质量、套管材质及腐蚀等诸多因素的影响,油水井套管损坏情况十分严重,严重影响了油田注采结构调整和注水开发效果。通过油田的开发历程可以看出,随着油田注水压力、地层压力的提高,套管损坏井越来越多。因此从油田套管损坏的分布、时间、井型、形态及层位等特征方面进行了统计分析,提出油田套管损坏发生的规律及特点,据此分析了低渗透注水开发油田套管损坏的主要影响因素和作用机理。在此基础上,通过对油田现场实际调查研究提出了预防套管损坏的综合配套技术措施,可为油田有效解决套管损坏问题提供参考。 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
