用曲射线法绘制地震剖面,是提高解释精度的一个方面。目前,在华北等地区已广泛采用。不论在理论上或实践上,都证明曲射线法比直射线法绘制剖面精度高。苏北地区,断层复杂,地层倾角变化较大。用直射线法绘制剖面,对于较准确地解释地下构造是力不从心的。为了制作适合苏北地区的曲射线量板,我们对两种方法作了试验和比较,下面是我们的一些粗浅体会: Using curved ray method to draw seismic sections is one aspect to improve interpretation accuracy. At present, it has been widely adopted in North China and other regions. Both in theory and in practice, proved that ray-ray method is better than the direct ray method to draw the profile. In northern Jiangsu, the faults are complex and the dip of strata varies greatly. Drawing the profile with the direct ray method is powerless to explain the underground structure more accurately. In order to make a curved plate suitable for northern Jiangsu, we tested and compared the two methods. Here are some of our superficial experiences:
