Title:
GAS-POTENTIAL PREDICTION METHOD AND APPARATUS BASED ON DOMINANT INCIDENT ANGLE AND FREQUENCY DOUBLE-DOMAIN ATTENUATION
Document Type and Number:
WIPO Patent Application WO/2024/067835
Kind Code:
A1
Abstract:
Provided in the present disclosure are a gas-potential prediction method and apparatus based on dominant incident angle and frequency double-domain attenuation. In the method, an attenuation attribute is captured for a pre-stack gather within a dominant incident angle range, the attenuation attribute is an improved high-frequency attenuation gradient attribute, a gas-potential sensitive factor is formed, and gas-potential prediction is completed. Further provided in the present disclosure are a prediction apparatus, a computer readable storage medium and an electronic device.
