过去 50 年来，采集地震数据的技术和硬件不断发展，而计算技术的进步也彻底改变了数据处理和解释。

“过去 100 年来我们在地震领域所做的一切都是一种演变。“我们做我们所做的事是因为我们无法正确地做事，”最近从 CGG 首席科学家职位上退休的萨姆·格雷 (Sam Gray) 说道。“我们所做的一切都是一种近似，我们越来越接近能够进行精确的科学。”

Techniques and hardware for acquiring seismic data have evolved over the last 50 years, while computing advances have revolutionized data processing and interpretation.

“Everything that we’ve done in seismic over the last 100 years has been an evolution. And we do what we do because we can’t do it correctly,” said Sam Gray, who recently retired from his post as chief scientist at CGG. “Everything that we do is kind of an approximation, and we’re getting closer and closer and closer to being able to do exact science.”
