  • 钻铤的钻井过程中主要起的作用

    钻铤是接在钻杆下端起加重作用的,钻铤的外行和钻杆差不多,比钻杆粗点,比钻杆重的多。钻铤:使用轧制或锻造的AISI4145H铬钼合结钢制造,对化学成分及微量元素的含量进行有效的控制。 钻铤(drillcollar)处在钻柱的Z下部,是下部钻

  • 钻井施工步骤包括哪几个部分

    钻探一口油气井,因钻井深度、地质软硬、压力、井程须求等不同因素,施工期从十几天到一年以上不等。钻井过程也相当错综复杂,我们仅讨论较重要的关键。1、下管套管套设计可说是钻井的重头戏。任何一口井在钻井过程中常会遭遇到数种不同的地质、深度或突发状

  • 钻杆修复时发现钻杆管体失效的原因

    钻杆管体中部失效的原因在于:钻杆由于在腐蚀介质下长时间存放而产生蚀坑,蚀坑周围存在微裂纹在钻井过程中,因承受弯曲交变应力,即在蚀坑底部这个应力集中的地方产生初始裂纹,随着服役过程的推移,微裂纹会慢慢扩展。由于该部位的正常磨损和偏磨,使壁厚变
