在中国南方有一类中小型盆地,它们的特点是垂直方向的多层结构和水平方向的多级分割,形成复杂的构造格局。复杂性就在于沉积深厚,岩相多变;数度侵蚀,火成常见;断层不少,构造陡倾;起伏频繁,上下不符。因此产生了复杂的地震地质条件和探测的技术问题,诸如各类多次波,侧面波的干扰,复杂断层,各种不整合,尖灭带,速度多变,深层畸变等,造成取得古生代地层内部波组的困难。文中提出了解决这些问题的观点和措施。
In southern China, there is a type of small and medium-sized basins. They are characterized by vertical multi-level structures and horizontal multi-level subdivisions, forming a complicated structural pattern. Complexity lies in the deposition of deep, rock phase changeable; several erosion, fire into the common; many faults, steep structure; frequent ups and downs, up and down does not match. As a result, complicated geological and geological conditions of exploration and technical problems of exploration have taken place, such as various types of multiple waves, side-wave interference, complex faults, various unconformities, sharp-edged zones, varying speeds and deep deformations, resulting in the acquisition of Paleozoic strata Internal wave group of difficulties. The article put forward the views and measures to solve these problems.
