油气井用隔板起爆器的起爆能力

摘要

为了提高油气井用隔板起爆器的起爆能力,在传统隔板起爆器的基础上,改变了其受主装药盲孔的几何结构和受主装药结构,设计出一种油气井用隔板起爆器,并对其进行了起爆能力的实验研究.实验结果显示,油气井用隔板起爆器起爆油气井耐温传爆管的最大空气隙距离为85 mm,而传统隔板起爆器和油气井耐温传爆管分别为20 mm和65 mm,因此,它的空气隙起爆能力很强.%A new kind of through bulkhead explosive initiator for oil well usage was designed in order to achieve stronger initiating ability in the air. Its initiating ability in the air was studied. The maximum air gap,through which the through bulkhead explosive initiator can initiate a secondary high explosive booster for oil well usage,is 85ram while the ones of a booster for oil well usage and a traditional through bulkhead explosive initiator initiating boosters for oil are 65 mm and 20 mm respectively. So the former is much stronger than the latter in the initiating ability in the air.
