提高调整井固井质量的重要途径——套管外封隔器固井

THE IMPORTANT METHOD TO IMPROVE THE QUALITY OF CEMENTING OF ADJUSTMENT WELL——OUTER CASING PACKER OPERATION

    摘要
  • 摘要: 钻调整井是老油区挖潜的主要手段,而调整井固井质量的好坏直接影响着二、三次采油产层的分层处理和挖潜增效,关系到老油区提高采收率的问题。目前,克拉玛依油田调整井固井质量合格率较低,固井后管外出油、出气或井内试不住压,在一定程度上影响了增产措施的实施,极大地影响了原油的增产、稳产。套管外封隔器可用于有高压气窜、恶性开漏等复杂情况井的固井,使固井质量有所提高。本文介绍了克拉玛依油田调整井中用套管外封隔器提高固井质量的情况。

     

    Abstract: Adjust well is the major method to increase production in the old oil field.The adjust well’s cementing quality will directly affect the separate zone production and well stimulation of the secondary and tertiary recovery and relate to improve recovery in old oilfield.In the recent time,the qualification rate of cementing quality in adjust well is low in Kelamyi oilfield.The oil and gas channeling occurs in the annulus after cementing and the pressure testing is often unsuccessful,which extremely affect the well stimulation and stable production.The outer casing packer can be used in the troublesome wells in which the high pressure gas channeling and the loss of circulation occur,to improve the cementing quality.In this paper,the application of outer casing packer in adjust well in Kelamyi oil field and improving cementing quality are introduced.
