鉴于浅海修井作业工况与陆地修井作业工况存在较大差别,在设计浅海修井机井架时需考虑其特殊性。在对浅海平台修井机井架的工况特点和使用要求进行分析的基础上,采用了具有一定大门高度的三段式塔形井架结构,并用船舶甲板油漆涂料进行防腐。论述了此类井架的静强度计算方法和稳定性计算方法,以及电算试验方法。对计算结果和试验结果进行了对比,结果相吻合。 相似文献

修井作业专家系统开发研究 总被引:1,自引:0,他引:1
随着油井开采时间的延长,油井事故逐年增加,油田修井任务繁重,修井技术人员匮乏,修井专家紧缺,修井数据管理不规范,迫切需要一套易操作的完善的融合了先进的修井经验和知识的“修井作业咨询系统”,以有效解决目前修井工作中存在的技术和管理问题,给油田修井作业提供可靠的技术依据。将专家系统与修井作业相结合,完成了修井作业专家系统的开发工作。从知识库的建立,知识获取,推理机制的实现等方面介绍了修井作业专家系统的开发过程。该系统的研制成功将为修井作业技术人员提供“专家”的意见,必将提高修井成功率、修井效率和技术人员的水平。 相似文献

一种自升自航式修井作业船的方案设计 总被引:2,自引:0,他引:2
为适应我国浅海油田的修井作业,进行了自升自航式修井船的方案设计。自升自航式修井船是一种特殊的工程船舶,它装有推进装置,能够自航,又装有桩腿,能像自升式平台一样在海上升起。该船的航行和就位不需要拖轮辅助,使用中机动灵活、工作效率高;该船结构尺度比较小,且比普通自升式修井平台造价低廉,经济效益好。 相似文献

在深水油气生产采用水下生产系统模式时,常规修井作业须动用半潜式钻井平台,由于高昂的修井成本限制了深水修井频率,使深水油气田在投产之后几乎很少实施后续的增产作业。但是,部分修井作业可以在不动生产管柱的条件下进行,例如采用小尺寸的修井隔水管及水下井口压力控制系统,单体工程船即可以实施修井系统的安装和修井作业,可提升修井的作业效率。 分析了深水水下井口修井的作业类型,针对不动生产管柱的轻型、中型修井作业,分析了修井系统的配置及关键设备特点和设计时应考虑的主要因素,给出了典型修井作业程序及作业风险应对方案,可为深水修井技术和装备的研发提供参考。 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
