“Ｓ”型射孔系研制成功地质矿产部西南石油地质局与兵器工业部第２０４研究所于１９９２年共同设计并研制成功了‘它”型射孔系。该射孔系在压裂弹中增设了“缓冲段”。它不仅可以自成体系，亦可与其它射孔管串相配进行复合射孔作业。该成果已获国家专利。由于射孔枪的筛... “S” perforated system was successfully developed The Department of Geology and Mineral Resources Southwest Petroleum Geology Bureau and Ordnance Research Institute No. 204 in 1992 jointly designed and developed a “it” type perforating system in the fracturing projectile The addition of a “buffer section.” It not only self-contained system, but also with other perforating string matching complex perforating operations. The results have been national patent.
