过油管张开式射孔器的研制

Development of Through tubing Folding Perforators.

袁吉诚，罗宏伟．过油管张开式射孔器的研制．测井技术，１９９８，２２（５）：３５７～３６１简要介绍了过油管张开式射孔器的研制情况。详细介绍了该射孔器的设计方案，并与国外同类产品的设计方案进行了对比。对研制中解决的关键技术如张开机构的可靠性、射孔弹的发射率与安全性以及枪架的破碎性等进行了简要的阐述。从进行的试验以及检测的结果来看，研制工作已取得成功，可投入生产施工。

The development of the through tubing folding perforators are outlined. Its design scheme is described in detail and it is compared with the design scheme of the similar products from foreign companies. The key techniques, such as the reliability of the folding mechanism, the fire rates and the safety of the charges and the crushability of the charge holder involved in its development are elaborated. The test and verification results show that the newly developed through tubing folding perforator is successful and can be put into production.
