Abstract

Método de inversión multi-parámetro utilizando inversión elástica. Este método descompone datos en grupos de compensación/ángulo y realiza inversión en ellos en orden secuencial. Este método puede agilizar significativamente la convergencia del proceso de inversión iterativa, y por lo tanto es el más ventajoso cuando se utiliza para la inversión de forma de onda completa (FWI). El presente procedimiento inventivo se beneficia de las relaciones entre la energía de reflexión y el ángulo de reflexión, o de forma equivalente, dependencia de compensación en la FWI elástica. La invención utiliza el reconocimiento de que los reflejos de amplitudes de ángulo pequeño (compensación cercana) se determinan ampliamente por la impedancia acústica sola (1), independiente para la mayor parte de Vp/Vs. Los reflejos de ángulo grande (compensación media o lejana) se afectan por Ip, Vp/Vs (2) y otros parámetros terrestres tales como densidad (3) y anisotropía. Por lo tanto, el método inventivo presente descompone datos en grupos de ángulo o compensación al realizar la FWI multi-parámetro para reducir la diafonía entre los diferentes parámetros de modelo que se determinan en la inversión.
