IMPERMEABLE AND COMPOSITE PERFORATING GUN ASSEMBLY COMPONENTS

摘要

A perforating gun assembly that includes at least one component that is constructed from a composite material and that is impermeable to wellbore fluids. The components may include the outer carrier and/or loading tube of a perforatin g gun, the connecting tubing of a gun release mechanism, and the gun connector used to attach adjacent perforating guns. The composite material is designed to be very brittle under dynamic impact. The component is made impermeable to wellbore fluids by including an impermeable liner therein. The impermeable liner can be bonded to the inner or outer surface of the component or can be embedded within the component. Since it i s brittle under dynamic impact, the composite component shatters into small pieces upo n detonation of the perforating gun.
