Abstract

La presente está relacionada con un método para el cálculo de una distribucion de tiempos de relajacion espín-espín. Las amplitudes de eco de espínson obtenidas por la integracion del equipo de los voltajes del receptor sobre una ventaja de tiempo. Un operador lineal es utilizado para formar elmapa de una distribucion de tiempo de relajacion para ecos de espín, producir una descomposicion de valor sencillo (DVS) del operador lineal,determinar los vectores de las DVS, y comprimir los datos de ecode espín usando los vectores. Para eliminar un cuello de botella de telemetría, el espectroT2 es calculado en la perforacion y se transmite a la superficie.
