哈萨克斯坦高压深井水平井钻井技术 总被引:1,自引:0,他引:1
针对哈萨克斯坦肯基亚克盐下油田高压深井水平井钻井在地质构造、钻井工艺的技术难点,利用最优化钻井理论,完成钻头选型和不同钻井方式下的钻具组合及钻井参数优选;在轨迹设计上根据油藏情况优选剖面类型;在钻进方式上由单一的滑动钻进或转动钻进转变为滑动与复合交替钻进;在仪器测量方面,针对塑料小球影响无线随钻系统正常工作和如何提高井下仪器有效工作时间问题,对无线随钻系统进行改进,制定了详细的安全技术措施并严格执行,成功钻成了6口水平井,成功率100%。定向井段的机械钻速由原来的0.5~0.8 m/h提高到1.0~1.2 m/h,钻成了哈萨克斯坦第一口千吨级油井H8010井。逐步摸清了哈萨克斯坦肯基亚克盐下油田钻水平井的一些规律,形成了一套较为成熟的高压深井水平井钻井工艺模式,为该地区进一步推广水平井开发提供了宝贵的经验。 相似文献

ADMa-1H井是伊拉克艾哈代布油田第1口大位移水平井,也是艾哈代布油田目前为止水平段最长、垂深最深的水平井。该井用常规随钻测量仪器(MWD)和螺杆动力钻具组合完成1 500 m的152.4 mm小井眼水平段的施工记录。针对大位移水平井轨迹控制难度大、水平段摩阻扭矩大、易发生井漏、卡钻等施工难点,通过优化井身结构设计、优选钻具组合和钻井参数、水平井轨迹控制技术研究,最终实现了全井井眼轨迹质量优质、无各类井下复杂事故发生。该井的成功为艾哈代布油田进行大位移水平井钻探作业提供了宝贵经验。 相似文献

水平井快钻技术在YT2-10H井的应用 总被引:1,自引:0,他引:1
由于水平井技术能在很大程度上提高油田的动用储量和采收率等优点,越来越被各油田单位所重视,但在水平井钻井施工过程中,如何提高钻井速度,缩短钻井周期一直是工程技术人员所困扰的难题.文章详细分析了水平井快钻技术在YT2-10H井的应用,通过对地层岩性和倾角的分析,科学的控制井眼轨迹,合理调整钻井参数,优化钻具组合和钻井液配置等方面入手,使水平井快钻技术的得到成功实践. 相似文献

吉木萨尔油田属于典型的页岩油油藏,采用"水平井+体积压裂"开发方式。为了探索页岩油产能建设新模式,2019年在该油田开展了超长水平段水平井试验。其中,JHW00421井水平段长3 100.0 m,刷新了多项非常规油气水平井钻井纪录。为了降低超长水平段下套管难度和风险,对下套管技术方案做了诸多优化,主要包括套管柱下入能力预测分析、通井钻具组合设计、井筒清洁参数优选、套管扶正器选型与使用等。研究与实践表明,采用多扶正器通井钻具组合、较高的钻井液排量和钻柱转速能够提高通井和井筒清洁效果,为安全高效下套管创造条件;采用滚轮扶正器、整体式弹性扶正器并优化安装位置,能够有效降低长水平段下套管阻力。此外,若常规下套管技术难以满足要求时,建议采用漂浮下套管技术,慎用或不用"上提下冲操作"。该研究成果能够为超长水平段水平井钻完井设计与施工提供参考。 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
