三维地震勘探的测量工作比起二维勘探来说有较大的差异,其最大优点是将现代化的电子计算技术应用到了测量工作之中,实现了计算、平差、检验,直到打印最终成果和编制成图工作的全部自动化。在野外施工中只要取得角度,距离、标高和仪器高程等原始数据,并根据要求设置标志即可,无须作任何现场计算工作。在一个三维勘探面积内,不可能也不必要条条测线都用仪器实测,只需对一部分控制测线用仪器实测,而其余的测线采用内插。三维地震勘探的测量方法有多种,无论采用哪种方法,都必须达到各项技术指标的要求。
The major advantage of 3D seismic survey is that it is compared with 2D exploration. The biggest advantage of 3D seismic exploration is that it applies modern electronic computation technology to surveying, and realizes calculation, adjustment and inspection until the final result is printed. All work done in the automation of charting. In the field construction, only the original data such as angle, distance, elevation and instrument elevation can be obtained, and the signs can be set according to the requirements without any on-site calculation work. In a three-dimensional exploration area, it is impossible and unnecessary to measure the line with the instrument, only a part of the control line is measured with the instrument, and the rest of the line is interpolated. There are many measurement methods for 3D seismic exploration. No matter which method is adopted, all the technical indicators must meet the requirements.
