射孔器腔内压力测试仪的高频动态补偿方法∗

摘要

Against the cavity pressure tester pressure pulse can’t be measured. A kind of high frequency dynamic digital compensation method is proposed according to the index. The perforating gun chamber pressure tester was designed,and we had a test under simulated conditions of bore pressure generator. The experimental results show the effectiveness of this method. The analysis of oil well perforating gun chamber pressure signal feature was made. Through the design of high frequency dynamic compensation digital filter system,a pressure pulse test was performed in harsh environments such as high temperature,high pressure and high impact. The purpose was reached in this method to provide reliable basis for the optimal design of tester.%针对腔内压力测试仪无法测得一次压力脉冲的问题，提出了一种按希望指标高频动态数字补偿的方法，通过射孔器腔内压力测试仪的设计实例并在爆炸洞模拟膛压发生环境下进行试验验证，说明了本方法的有效性。分析了石油井下射孔器腔内压力信号的特性，通过高频动态补偿数字滤波系统的设计，从而达到在高温、高压、高冲击等恶劣环境下测得一次压力脉冲，为测试仪的优化设计提供可靠依据的目的。
