东昆仑山北缘山前构造带的特征及其对油气成藏的意义
Structural characteristics of the northern foreland belt of East Kunlnn Mountains and their significance for oil and gas accumulation
摘要
Abstract
The north foreland of East Kunlun Mountains, located in south Qaidam Basin, has experienced dual events of die uplift of East Kunlun Mountains and the strike-slipping of the Altyn Tagh fault since Mesozoic and Cenozoic period. Controversy still exists concerning the regularity of oil and gas accumulation and storage. Based on the new interpretation of the seismic data and other data as well as studies of the structural characteristics, activity properties and epochs and the control of the main faults over oil and gas resources in the study area, the authors hold that the north edge fault of East Kunlun Mountains was related to the uplift of the Kunlun Mountains and the activity of Altyn Tagh fault. The early stage of Miocene and the last phase of Early Pleistocene were main faulting active stages. This fault not only controlled the formation of hydrocarbon depressions and oil and gas resources but also changed the oil accumulation and formed secondary oil pools. Therefore, it is likely to find the same type oil and gas reservoirs in the Qaidam Basin through the study of the evolution of East Kunlun Mountain fault.关键词
