Abstract: A composite drill gun for use in a wellbore environment can include a detonation housing containing a detonation source, a composite carrier containing one or more encapsulated charges, and a detonation train connecting the detonation source to the encapsulated charges. The detonation source and each individual encapsulated charge are all sealed with respect to the wellbore environment, and thus the carrier need not be sealed with respect to the wellbore environment. The carrier can be made out of composite materials without worry of leaks into the interior of the carrier, as the detonation source and encapsulated charges are all sealed with respect to the wellbore environment. The composite carrier can be easily drilled out of the wellbore after detonation.

Abstract translation: 用于井筒环境的复合钻杆可以包括含有爆震源的爆震外壳，含有一个或多个封装装药的复合载体，以及将爆震源连接至封装装药的爆震链。 爆震源和每个单独的封装装药相对于井筒环境全部密封，因此载体不需要相对于井筒环境进行密封。 载体可以由复合材料制成而不用担心泄漏到载体内部，因为爆炸源和封装的装药都相对于井筒环境被密封。 爆炸后，复合载体可以很容易地钻出井筒。
