电测作业的井筒完整性标准

Standard on well integrity in the process of electric log

介绍了适用于电测作业的井筒完整性标准、要求与指南。电测作业是井筒全生命周期内,在钻井、测试-试油、完井、采油气生产(包括:注水、压裂、酸化、增产等)以及修井作业,直到关停、报废前,经常要进行的作业。说明了电测作业的要点并用7个井筒屏障图来说明主要的电测作业要求,阐述了井筒屏障组件验收标准。同时介绍了电测作业时的井控工作。特别强调电缆高压动密封技术的重要性,介绍了"三级注脂动密封新技术"的研究和应用情况。

The well integrity standards,requirements and guidelines suitable for electric log operation were introduced.Electric log operation is often carried out in the whole life cycle of a well,including well drilling,test-well test,well completion,oil and gas production(e.g.water injection,fracturing,acidizing and stimulation)and workover,until the well is shut down or abandoned.Then,the key points of electric log operation were illustrated,the main electric log requirements were described by using 7 well barrier diagrams,and the acceptance standard of well barrier element were elaborated.Finally,the well control in the process of electric log operation was introduced.What’s more,the significance of cable high-pressure dynamic seal technology was particularly emphasized,and the research and application situations of “three-stage grease injection seal technology” were described.
