BIDIRECTIONALLY TESTABLE SEAL CONFIGURATION

摘要

A seal assembly made up of multiple opposite oriented unidirectional seals. The assembly includes a dedicated test port for each of the unidirectional seals. Thus, a first test port may be directed at the first seal such that if the first seal leaks, the second seal is configured to collapse and allow a second test port coupled thereto to detect the leak of the first seal. By the same token, the first test port may be used to detect any leak in the second seal which is detectable as the first seal collapses as a result of the leak. This unique type of architecture allows for a reliable manner of testing a multiple seal assembly that may be prone to leaks from multiple directions, for example from either a bore or an annular side of a tubular. This renders the bidirectionally testable seal configuration beneficial for incorporation into downhole completions hardware such at the location of a test gauge secured to a carrier device.

主权项

1. A tubular carrier device for disposal in a well at an oilfield, the carrier device comprising:
a tubular mechanism with a bore side at an interior thereof and an annular side to an exterior thereof; a test gauge for acquiring information from both the bore side and the annular side of the tubular mechanism; and a seal assembly at an interface between the test gauge and the tubular mechanism, the assembly having a bore side test port device pressurizably coupled to a first unidirectional seal and annular side test port device pressurizably coupled to a second unidirectional seal, the bore side test port device configured to detect failure of the second unidirectional seal and the annular side test port device configured to detect failure of the first unidirectional seal.
