【摘要】 增压多级起爆射孔技术通过增压装置产生压力,利用液体的传压原理,将下一级起爆器起爆达到多级起爆的目的,完成射孔过程。该技术大幅度减少夹层枪的使用,减少由于渗漏、断爆等引起的工程事故,提高安全传爆成功率。利用有限元方法及流体分析程序对油管在井下围压和增压作用下的变形和油管内井液在一定压力作用下的压缩性及由此引起的相关参数变化及沿程压力损失进行数值仿真和优化计算,为增压多级起爆技术的研究提供科学基础,从而提高产品的安全可靠性和实用性,减少实验成本。本文主要介绍了增压多级起爆设计方案的机理及技术指标,并对增压装置的研制及火药的设计进行了研究。本文对研制的增压装置进行了耐压、高温、隔板传爆裕度试验。研制的增压多级起爆装置进行了现场作业实验,取得了很好的效果。更多还原

【Abstract】 Perforating technology for booster multistage blast through booster devices produces pressure,utilizing transmission pressure principle of liquid and firing the next detonator in order to achieve the goal of multi-stage inition, so that perforation process is done.This technique has largely reduced the usage of interbedded gun,decreasing engineering accidents due to leaking、failed blast,therefore,increasing success ratio of transmission blast safely.Finite element method and fluid analysis program and the confining pressure tubing in underground pressurized pipe under the action of deformation and fluid within the well under a certain pressure and the resulting compression of the relevant parameters and the pressure loss along the numerical simulation And optimization for the multi-stage booster detonation provide the scientific basis of technology to improve product safety and reliability and availability, reduce the cost of experiments. This paper developed a pressure booster devices, high temperature, partitions Booster margin test.This paper describes the design of pressurized multi-level initiation mechanism and technical indicators, and the Device and gunpowder booster design was studied. Developed multi-stage booster detonation device on-site role in experiments, and achieved very good results.更多还原
