摘要
Abstract
In order to improve the recovery rate of ultra-high temperature oil and gas wells and enhance the perfora-tion performance of perforating charges,a preparation method of high-temperature resistant polymer bonded explosive(PBX)for perforating charges was proposed.Firstly,two crystal forms of 2,6-diamino-3,5-dinitropyrazine-1-oxide(LLM-105)were prepared using recrystallization technology:long rod-shaped and block shaped.Secondly,the formula for LLM-105 based PBX was determined through theoretical calculations.Next,LLM-105 based PBX was prepared using the water suspension method and its thermal stability was tested.Finally,the explosive performance of the prepared PBX was tested using ground static armor penetration test.The results show that the loose packing density of LLM-105 based PBX reaches above 0.80 g/cm3,and the packing density reaches 1.75 g/cm3.Compared with S992 explosive based on HNS and Y971 explosive based on PYX,the prepared LLM-105 based PBX charge has a penetration depth increase of over 16%and excel-lent perforation performance.关键词
