Method of PHA and Its Application in DST String Design
-
摘要: 文章对预先危险分析方法PHA(PreliminaryHazardAnalysis)作了简单介绍。重点介绍了PHA方法在钻杆测试DST(DrillStemTesting)管柱设计中的应用,提出了利用PHA方法从安全的角度对DST管柱进行修改的过程,指出它能有效地消除或减少DST测试过程中的事故隐患,是规范DST测试的重要措施之一。Abstract: In this paper, method of PHA have been generally introduced focusing on the application to DST string design. The process of modifying DST string design with PHA are given. It points out that the application of PHA can reduce or remove accident hidden trouble effectively and that is one of the important step in criterion DST.
