【摘要】：耐温性能是射孔器材的重要技术指标之一,直接影响施工的安全性和油气井产能。射孔器的耐高温性能检验在国内执行的是标准GB/T 20488-2006《油气井用聚能射孔器材性能试验方法》。石油工业油气田射孔器材质量监督检验中心是国内唯一的射孔器材检测机构,原有的高温检测试验装置,是1995年随API RP43整个试验系统引入的,在使用过程中发现其存在一些技术缺陷,不能满足试验需要。因此,需研制新的高温检测试验装置来检验聚能射孔器的耐高温性能。由于是火工品耐温试验,各环节首先考虑的是安全,然后是试验方法的科学合理、结果准确。因此,将试验过程分解为加热、运移和射孔试验三部分。加热炉要求满足现场需要的的温度指标,能够避免加温过程中意外爆炸时射流对加热炉的损害；运移系统的动作必须快速准确、安全可靠；射孔试验能够为射孔器打靶提供场所,同时射孔时射流不偏出靶,保证试验结果的准确性。针对这些问题,本文通过数值模拟、对比试验等一系列的研究,最终研制了一套完整的射孔器高温检测装置,主要包括加热炉、试验容器、靶架、温控系统和运移系统,能够实现射孔器的从工作台运移至加热炉,加温后运移至试验容器内起爆,并取出回到工作台的全自动化操作,各项技术指标均达到试验要求,可以进行加热的温度上限为300℃,保温时间120h,lm射孔枪8发射孔弹的射孔试验,实现了国内高温射孔器的检测,对我国高温弹的研究和发展将起到促进作用。
[Abstract]:Thermal resistance is one of the important technical indexes of perforating equipment, which directly affects the safety of construction and the productivity of oil and gas wells.The test of high temperature resistance of perforator in China is the standard GB/T 20488-2006 "performance Test method of Oil and Gas well shaped perforating equipment".The quality supervision and inspection center of perforating equipment in oil and gas field of petroleum industry is the only testing organization in China. The original high temperature testing equipment was introduced in 1995 with the whole test system of API RP43.In the process of use, it is found that there are some technical defects which can not meet the needs of the test.Therefore, it is necessary to develop a new high temperature test device to test the high temperature resistance of the shaped perforator.Because it is pyrotechnic test, the safety is considered first, and then the test method is scientific and reasonable, and the result is accurate.Therefore, the test process is divided into three parts: heating, migration and perforation test.The reheating furnace needs to meet the requirements of the field temperature index, which can avoid the damage caused by the jet during the accidental explosion in the heating process, and the movement of the transportation system must be fast, accurate, safe and reliable.The perforation test can provide a place for the perforator to target, and the jet does not deviate from the target during perforation, which ensures the accuracy of the test results.Aiming at these problems, through a series of research, such as numerical simulation, contrast test and so on, a complete set of high temperature detection device of perforator is developed in this paper, which mainly includes heating furnace, test vessel, target frame, temperature control system and transportation system.The perforator can be moved from the worktable to the heating furnace, and then moved to the test vessel after heating to start the explosion, and the automatic operation of the perforator can be removed back to the workbench. All the technical specifications meet the test requirements.The perforation test of 8 perforating projectile with heating temperature of 300 鈩，
