多年以来，传统的地震检波器--模拟信号输出，一直占据主要的地位（中国现在是主要的生产供应商）。进入数字化时代后，须然有不少公司投入巨资研发3分量数字检波器--MEMS SENSOR。但由于成本（售价太高），相关技术（如数据处理算法跟进），市场接受等因素，推进缓慢。在这个市场中，除了传统的大公司，SERCEL, I/O, INNOWA， BGP 等投入巨资研发外，一年前，HP, SHELL 联合进入这一市场，开发DIGTIAL MEMS SENSOR.两大巨头的加入，无疑会加剧这一市场的竞争程度。但似乎也在告知，检波器的数字化时代进程会加快。

现在国内的检波器制造商大多数仍然是传统的模拟信号检波器。除了BGP对MEMS 约有投入外，其它公司几乎没有研发能力或没有意思到这一趋势。本人涉足地震物探行业不久，有两个问题工请大家讨论：

1）地震检波器的数字化会在2-3年之内实现吗？

2）单点数字检波器是否能够取代现在的模拟信号检波器串？有没有算法可以验证（有待数据处理的跟进）？
SEISMIC INTRUCMENTS, WESTERNGECO 是这一观点的强力推手。如果这一观点不成立，则其数字化进程会受到大大减缓。现在的模拟检波器串一般采用6,12,18,24。 现在还有采用75个串，可以想象其成本有多高。

3）如果今后的数字化检波器（单分量）成本控制为现在传统模拟检波器的两倍以内， 你认为用户会接受吗？则其数字化进程是否会加快？

Most of my time, i worked in universities and my background is in mechanical area. Recently, I am working with a seismic equipment project.I have known some of the hot topics in this area and I just have some questions. I am not working with geophones. however, i am interesting some of the topics. Anyone are welcome to open your minds for any of the topics.

I don't know much the situation in China. In US, especially offshore deepwater, analog geophone is out the picture. With seismic shoot average sevcral million dollars per block, the service company must offer a better equipements.

Thanks for ytlee's opinions. I am not familiar with deepwater exploration. I am doing the landing seismic exploration in north american. I knew it's almost 90% of the customers who are using the analog geophones in their land seismic exploring. i recently read some news and thinking about these questions. Just want share with the one who is also interesting it.
