| 摘 要： | 本文据地震和地质观察资料，解释和阐述了塔里木盆地北部前陆区库车坳陷中、新生界滑脱推覆构造平面、剖面特征，结合前缘隆起区有关资料，提出了库车坳陷滑脱推覆构造的成因机制，并对库车坳陷油气进行了初步评价，认为秋里塔克弧形构造内侧断弯褶皱、楔状三角体及推覆构造前缘盐构造控油有利。

| Abstract: | This paper describes detailedly the characteristics of decollement thrust zone both in plane and in section of Mesozoic-Cenozoic rocks in the Kuche depression in the south foreland North Tarim basin by an analysis of the geophysical and geological data available. A mechanism of the formation of the thrust zone is first put forward and is followed by a preliminary evaluation of the oil-gas resources. The fault bend folds behind the Qiulitake arc and the triangle zone and the salt domes in the front of the thrust stack are considered the likely oil traps. |
