昆特依凹陷中生界、新生界发育特征及构造演化分析
|
摘要
昆特依凹陷位于柴达木盆地北缘断块带西段,紧邻冷湖和鄂博梁—葫芦山构造带,是柴达木盆地西北部重要的油气勘探潜力区域。通过对昆特依凹陷内部中生代、新生代地层分布特征的分析,结合地震资料地质解释,认为在中生代末造山后的陆内调整时期,昆特依凹陷内分割性断块发育,形成压陷型分隔性断块坳陷;新生代喜马拉雅构造运动对柴达木盆地的影响主要表现为压扭性构造应力场的作用,伴随阿尔金走滑断裂的活动,昆特依凹陷受其影响和制约,发育形成压陷型沉降坳陷。昆特依凹陷内的潜伏背斜构造在新生代早期开始发育,第四纪最终定型。
Kunteyi depression is located in western fault block of northwestern Qaidam basin,near the Lenghu structure zone and Eboliang structure zone.It is one of the most important potential areas of oil and gas exploration in northwestern Qaidam basin.By analyzing the Mesozoic and Cenozoic stratigraphic characteristics and geological interpretation of seismic data,the paper comes to conclusion that the prototype basin of Kunteyi depression was extrusion-type and intersected block depression in Mesozoic because of a large number of intersected block in depression.With Himalayan tectonic movement and Altyn Tagh fault activities,Qaidam basin was in the pressure-shear stress field in Cenozoic.Kunteyi depression was also in the pressure-shear stress field and developed into extrusion-type depression in Cenozoic.With the Altyn Tagh fault activities,Kunteyi depression was in the pressure-shear stress field in Cenozoic.The deep structural belt began to develop in early Cenozoic and formed in Quaternary.
