Abstract

En fremgangsmåte for å dempe spenningsbølger som forplantes fra detonasjon av en sprenganordning i en brønnboring, for å beskytte en anordning plassert i brønnen, omfatter de trinn å anordne en sjokkdemper mellom en sprenganordning og en utstyrspakke; detonere sprenganordningen slik at det forplantes en spenningsbølge mot sjokkdemperen og utstyrspakken; og reflektere en del av spenningsbølgen i sjokkdemperen. Sjokkdemperen kan omfatte én eller flere grenseflater dannet mellom materialer med ulik akustisk impedans. Sjokkdemperen kan reflektere en kompresjonsdel av spenningsbølgen ved én grenseflate og en strekkdel av spenningsbølgen ved en annen grenseflate.
