油管传送射孔同其它射孔方式相比,不仅能确保高压油气井的射孔施工安全,较好地解决大斜度井及水平井射孔施工的问题,而且能在全井段实现合理负压差条件下射孔作业,有利于油、气层的保护。中原油田文72区块9口井射孔效果对比说明,用常规方法射孔日增油仅3.1t,而油管传送射孔日增油平均达20.65t,效果显著。将油管传送射孔技术与气体压裂等其它相关技术结合,将进一步拓宽油管传送射孔的应用范围
Compared with other perforation methods, the tubing delivery perforation can not only ensure perforation construction safety of high-pressure oil and gas wells, but also solve the problems of perforation construction in high-inclination wells and horizontal wells well, and can achieve a reasonable negative Perforation under pressure conditions, is conducive to the protection of oil and gas layers. Comparison of the perforation results of 9 wells in Block Wen 72 of Zhongyuan Oilfield shows that the conventional method increases the perforation oil by only 3.1t, while the average daily oil perforation increases by 20.65t. The result is remarkable. Combining the tubing-delivery perforation technique with other related technologies such as gas fracturing will further broaden the range of applications for tubing-delivery perforations
