【摘要】：电火花震源在海洋石油和工程物探上的应用越来越广,它的地位不容忽视,由于电火花震源的高频特性,使得它的分辨率非常高,虽然能量不及炸药,但炸药的一致性不及电火花震源,所以电火花震源在保证一定的能量的情况下,重复测量的结果也是可以令人满意的,重复测量后经过叠加就可以得出令人满意的结果；伪随机编码的实现更是可以让其分辨率大幅提升,它的特点是能量不很大,但是经过伪随机算法的提升,让其分辨率有了质的变化。本论文设计来源国家地震局在西宁河断裂带的地震监测的项目,该项目需要电火花震源在井中发出弹性波,在断裂带的另一侧放置大量检波器,来测量地质的情况,由于不同地质的波形是不同的,可以根据多条波形来判断断裂带的情况,而以前都是手动的机械按钮来操控仪器的运行,在工作测量的过程中,多有不便,而且不能实时查看仪器的各种参数和数据的情况,所以需要一种更好的控制方式来提高工作效率。
[Abstract]:The application of EDM source in offshore oil and engineering geophysical exploration is more and more extensive, its status can not be ignored. Because of the high frequency characteristic of EDM source, its resolution is very high, although its energy is not as high as explosive. But the consistency of explosive is not as good as that of electric spark source, so the result of repeated measurement can be satisfactory under the condition of guaranteeing certain energy. After repeated measurement, satisfactory results can be obtained. The implementation of pseudorandom coding can greatly improve its resolution, its characteristic is that the energy is not very large, but through the pseudorandom algorithm, its resolution has changed qualitatively. The design of this paper comes from the project of seismic monitoring in the Xining River fault zone by the State Seismological Bureau. This project requires the EDM source to send out elastic waves in the well and place a large number of geophone on the other side of the fault zone to measure geological conditions. Because the waveforms of different geology are different, it is possible to judge the situation of the fault zone according to multiple waveforms. But in the past, the manual mechanical buttons were used to control the operation of the instrument, and in the process of working and surveying, it is often inconvenient. Moreover, it can not view the parameters and data of the instrument in real time, so a better control method is needed to improve the working efficiency.
