Abstract
A technique facilitates mitigation of shock loads. Subterranean communication systems may comprise components susceptible to various shock loads. A shock mitigation system is physically coupled with the subterranean communication system to mitigate such shock loads. The shock mitigation system comprises components selected to enable reduction of various effects of shock loads, e.g. shock loads resulting from perforating procedures, which could otherwise be detrimental to continued operation of the subterranean communication system.
Claims18
A system for use in a well, comprising:
- a tool string deployed in a wellbore, the tool string having:
- a perforating gun assembly;
- an acoustical communication system;
- and
- a shock mitigation system mounted along the tool string to mitigate shocks to the acoustical communication system resulting from firing of the perforating gun assembly, wherein the shock mitigation system comprises an acoustical clutch.
A method, comprising:
- coupling a perforating gun assembly into a tool string;
- providing the tool string with a communication system for transmitting telemetry signals along the tool string, wherein the communication system is in the form of an acoustical communication system having an acoustical rod member used to carry acoustic signals;
- and
- protecting the communication system against shock loads via a shock mitigation system operatively coupled with the communication system.
A system, comprising:
- a subterranean communication system susceptible to shock loads;
- and
- a shock mitigation system physically coupled to the subterranean communication system, the shock mitigation system comprising a clutch which enables movement of at least a component of the subterranean communication system when subjected to a sufficient shock load, the shock mitigation system further comprising an axial shock mitigator and a lateral shock mitigator.
