高温高压井测试联作射孔技术研究及应用

摘要

For ultra deep wells under high temperature and high pressure (HTHP),it is very difficult to implement the perforating and testing combination technology with low success rate which its construction requirements cannot be met by conventional equipments.In view of the perforating requirements in HTHP wells,the construction requirements of the perfo-rating and testing combination technology were met by means of meticulous designs of perforating equipments,priming de-vice,sealing elements,and so on.The technology has been applied successfully in Xuwen X3 well.%高温高压超深井测试联作射孔难度大，成功率低，常规器材不能满足施工要求。针对高温高压井射孔要求，通过对射孔器材、起爆装置、密封件以及仪器设备等进行精心设计，使其满足高温高压超深井射孔测试联作的施工要求。该技术应用于徐闻X3井，射孔一次成功，射孔发射率100％。
