Abstract
Способ идентификации пассивных сейсмических событий в сейсмических данных, которые содержат, по меньшей мере, трассы первых сейсмических данных, зарегистрированные на первом сейсмическом приемнике, и трассы вторых сейсмических данных, зарегистрированные на втором приемнике, пространственно отнесенном от первого приемника, заключающийся в том, что определяют общую меру подобия для пары событий в сейсмических трассах. Общая мера подобия указывает на подобие между событиями, зарегистрированными на первом сейсмическом приемнике, и подобием между событиями, зарегистрированными на втором сейсмическом приемнике. В одном способе общая мера подобия представляет собой общий коэффициент взаимной корреляции. Общий коэффициент взаимной корреляции находят путем определения первого коэффициента корреляции для пары событий на основании данных, зарегистрированных на первом приемнике, и определения второго коэффициента корреляции для пары событий на основании данных, зарегистрированных на втором приемнике. Общий коэффициент корреляции для пары событий может быть получен по первому коэффициенту корреляции и второму коэффициенту корреляции с помощью процесса усреднения. Общую меру подобия можно сравнивать с порогом, чтобы определять, образует ли пара событий дублет. Способ позволяет идентифицировать дублеты в реальном масштабе времени или почти в реальном масштабе времени.
