The application of box wave technique in planning field survey system

The box wave technique can figure out the velocity and propagation direction of noise wave and the ratio of signal to noise, also test multifarious geophone arrays to gain the best economical and effective array. Firstly, the application of box wave technique in Shuntuoguole area is presented. The number of geophone in array, different array length, various array figure and array method between in processing and in field are analyzed and compared,and the following summing-ups are found that the geophone array is a essential method to improve the signal/noise ratio, and the dynamic range and the ability to decrease the noise of the geophone array in processing are better than that in field, then after the static correction, the geophone array in processing will keep the high frequency component to increase the resolution. Lastly, a new single-geophone multi-line 2-D seismic survey system is designed. This method will increase the seismic wave resolution and signal/noise ratio of target reflector in complicated area.Otherwise the survey system will induce flexibility in processing, and is highly suitable for collecting seismic data by digital geophone.
