Discussion on Evaluation of High-temperature and Ultrahigh-temperature Jet Perforator in GB/T 20489-2006 |
| |
| Abstract: | The defects in the standard ＂General Requirements for Perforator Materials for Oil and Gas Wells＂（GB/T 20489-2006）that the heat-resistance indexes of high-temperature and ultrahigh-temperature jet perforators are not reasonable and there are not unified evaluation indexes are pointed out. The heat-resistance performance of the jet perforator is classified and the evaluation methods and indexes of it are determined through the analysis of the downhole working conditions, the time for site construction and the technological level of domestic jet perforators, which can provide the basis for the selection of perforators and the revision of jet perforator standards. |
