高温高压超深井中途测试工艺的改进及应用

Improvement and Application of Open Hole Testing Tech in HT, HP and Ultra-Deep Well.

根据胜利油田高温高压井测试的特点,分析了测试工作的重点、难点,提出了一系列技术改进措施。用HST工具取代MFE测试工具、VR安全接头取代P-T封隔器,在测试管柱、测试压差、测试制度等方面进行优化创新。经现场实际应用,测试成功率和施工质量明显提高。

According to testing characteristic in HT and HP well in Shengli oilfield, focal and difficult point of the testing work are analyzed, and a series of improving measures, using HST instead of MFE and VR safe connection instead of P-T packer, optimization and innovation are brought in testing pipe string, differential pressure and testing system etc, are provided. By application in field, successful rate of testing and quality of construction are remarked raised.
