一、一种引人注目的构造型式我国南方散布着一些中新生代红色盆地,盆地中红层变动轻微,断层以正断层为主,近年来的地质调查和钻探发现,在构造上似是简单的红层中有一些巨大的有老岩层卷入的逆掩断层。又如在衡阳盆地中部茅桐桥一带为找油而布署的衡3井,预计基底深约4000米,但在钻深1100米竟遇上古生界,于1800米又穿过上古生界复见红层,上古生界好象夹在红层之中.在红层中出现这些老岩层卷入的复杂构造,令人费解,而且直接影响生产实践。通过研究,
I. A striking structural type Some Mesozoic-Cenozoic red basins are scattered in the south of China. The middle red beds in the basin fluctuated slightly and the faults were mainly normal faults. In recent years, geological surveys and drilling discoveries are structurally simple There are some huge red beds in the old rock involved in the inverse fault. Another example is in the central part of the Hengyang Basin Moutong Bridge to find oil and the deployment of Heng 3 wells, the basement is expected to be about 4,000 meters deep, but drilling depth of 1100 meters actually met the Paleozoic, at 1,800 meters through the Paleozoic complex See the red layer, the Upper Paleozoic seems to be sandwiched between the red layer in the red layer appear involved in the complex structure of these old rock formations, it is puzzling, and directly affect the production practice. Through research,
