ANHYDROUS BORON-BASED TIMED DELAY PLUGS |
摘要 |
A well tool for use with a subterranean well can include an elongated passageway and a plug which prevents fluid communication through the passageway for a predetermined period of time. The plug can including an anhydrous boron compound, whereby the predetermined period of time is determined by a length of the anhydrous boron compound. A method of operating a well tool in conjunction with a subterranean well can include exposing an anhydrous boron compound to an aqueous fluid, with the anhydrous boron compound being included in a plug which prevents fluid communication through a passageway of the well tool. The well tool can be operated in response to fluid communication being permitted through the passageway a predetermined period of time after the exposing step. |
