摘要
相控震源在煤矿勘探领域广泛应用。针对相控震源非一致性问题,首先介绍了相控震源的工作原理,给出2子站相控信号模型。根据相控震源勘探的精度要求,提出了相控震源一致性评价方法。理论及数值模拟证明,相控震源一致性评价方法准确可靠,能够客观评价相控震源的应用效果,对相控震源应用于煤炭资源勘探与开发具有重要意义。
The phased array vibrator system(PAVS) is widely used in coal exploration. Focuse the consistency of signature of PAVS, firstly introduced the principle of PAVS, then give signature model of two sub-station of PAVS. According to the exploration accuracy require of PAVS, put forward the evaluation method of consistency of PAVS. Theory and nume modeling showed that the consistency evaluation method is accurate, reliable and it objectively evaluate the application effect of PAVS, This evaluation method would be of significance in coal exploration and development using PAVS.
