| Stereo-Geology and Oil-Gas Prediction of the Qaidam Basin |
| Stereo-geology of the Qaidam basin and their characteristics; It is mainly re-flected through the contour maps, isopch maps, profiles and geological maps of various depths of the basins structures, their characteristics map be summerized asfollows:
1. The inheritance and disagreements of the structures. In general, there is a good in-heritance between the basement structures and the cover structures, there exist a pre-Mesozoic reversed S-shaped system in the basment and a Meso-Cenozoic reversed S-shaped system in the cover. The two system are roughly inheritance.
2. The history of developmenf and evloution of the basin, from NW to SE, the struc-tures and deposits of the basin show the features of overloppig in the east and offlaping in the west. The evolution of the lake basin can be divided into three-stages, and have record-ed the development regularitites of structures, deposits and oil-gas.
Hydrocarbon sources and oil-gas prediction:
1. The paleozoic sources and their prediction, there are the possibility of finding Pale-ozoic marine hydrocarbon sources in the basement of the Delingha depression and the base-ment of the southwestern basin.
2. The Mesozoic sources and prediction of the Meso-Cenozoic petroleum provinces. With the Huangshi-Niubizilinang fulated rise belt as the boundary, the authors have divided the wide area north of Nan Us-Yiliping-Nanbazian into the western and the northeastern prospective petroleum areas. |
