测井事故的认识及处理工艺 总被引:1,自引:0,他引:1
测井仪器和电缆在井下遇卡,在地球物理测井中是经常发生的。电缆测井事故能否得到恰当处理不仅影响事故处理费用的多少,有时甚至可能关系到一口井的成败,因此测井仪器解卡打捞工艺是测井作业的重要组成部分。测井作业的打捞作业分为两大范畴:一是裸眼打捞,二是套管内打捞。落鱼形状分为管状物及绳状物。解卡打捞工作必须准确掌握:井况数据、落鱼情况、打捞工具组合、鱼头情况等。本文结合测井事故的处理情况,认为机械原因、钻井液性能和人为原因是造成电缆测井事故的主要原因,并介绍了常见测井事故的工具配备及处理工艺。 相似文献

试井测试过程中,由于种种原因造成试井钢丝落井。在修井作业中,对试井钢丝钢丝绳等软落物的打捞,虽然难度不大,如果措施或工具选择不当,也会造成井下打捞复杂化。例1:鄯4-21并复杂处理事故处理鄯4-21井为鄯善油田的一口气举采油井。作业下外约打捞井内钢丝时,由于管柱下人太深(3116m),在起油管至1570m时发生通卡。上提负荷在12t—30t之间波动.油管呈跳跃式起出,当起至318根油管时,井内管柱卡死,上提管柱至40t时油管脱扣,后下滑块捞矛打捞无效,造成井下复杂。井下落物为60.3加大油管3根、洗井短节1个、外钩1只以及2300m试井… 相似文献

井下作业管柱力学分析软件及应用 总被引:5,自引:1,他引:4
井下作业技术作为石油和天然气勘探开发的重要工程技术和手段,近年来取得了显著的进步,做出了重要贡献。随着钻井技术的不断发展,井眼越来越复杂,对井下作业提出了更高的要求,以前单凭经验来进行操作的井下作业已经不适时宜了,经常造成各种井下管柱事故。井下作业管柱受力分析软件在设计过程中用于预测某些潜在危险,尽量避免作业事故发生,使得设计更为合理、切实可行;在作业过程中用以分析某些事故原因,以便针对性地来处理问题,节约事故处理时间,降低作业费用,提高作业效率。该软件可以对起下管柱过程、压裂过程和打捞过程等的管柱力学状态进行计算,并对油管的长度进行初步优化。该软件无论是对作业前的室内设计还是现场作业过程中的作业管柱受力分析都有一定的指导意义,在大港、长庆等油田得到了初步应用。 相似文献

在多压力系统的长段裸眼内,钻遇高压油气水层时,往往出现“下吐上漏”等复杂情况,甚至出现卡钻事故。其处理难点在于,若先堵漏,堵漏液易被高压地层流体冲走;若先压井,又会发生井漏。一些井由于处理方法不当,虽投入大量人力、物力、财力仍出现井眼报废,造成巨大损失。满西2井在处理卡钻事故的套铣作业中,遇到“下吐上漏”的复杂难题。经对井下情况分析后,提出处理复杂情况的合理的堵漏液配方和浓度;堵漏液走前,压井液走后;施工中合理控制回压;允许少量漏,不允许有增量。采取堵漏压井同时进行的方法,成功地解除了该井的复杂问题,为处理类似复杂情况的井提供了实例。 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

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

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
