摘要
本文较系统地讨论了炸药震源激发子波的形成、拾取及其运动学、动力学、频率响应等特点,提出优质的震源激发子波是获得高品质地震资料和推进采集工作量化进程的基础和先决条件。在理论研究结合实际试验工作的基础上,提出了选取最佳井深等激发因素可操作的实用方法。
Abstract
The generation and extraction of dynamite source wavelet as well as its kinematic, dynamic and frequency responses are discussed systematically in the paper. High quality source wavelet is a prerequisite to high quality seismic data and is also the basis of progressing toward acquisition quantification. By combining theoretical research with field tests, we put forward a practical method for determination of optimum excitation depth.
