低频地震勘探与低频可控震源
|
摘要
低频地震勘探是近年来非常"热"的话题,本文探究了为什么低频地震勘探能够如此吸引众人的眼球,而低频可控震源为什么"千呼万唤"始出来?低频地震信号激发技术究竟面临哪些挑战?低频可控震源有哪些关键的技术参数?文中还结合KZ-28LF低频可控震源在国内开展的先导性试验,为业界展示其低频信号激发技术在解决油气问题方面的能力。
Low frequency seismic was a hot topic in geophysical industrial in recent years.The paper will present the reasons that why low frequency seismic could be so interested to those people,and why it was so hard to develop low frequency vibrator in the past.The paper also introduced the challenges that the vibrator may have during low frequency signal delivery to the ground and the key parameters that low frequency vibrator should have.The demo trial of low frequency seismic based on KZ-28LF was presented to show its capability in reservoir prospecting.
