摘要: 分析了盆地重力场、磁场和温度场特征,根据地球物理场信息探讨了盆地沉积构造、区域构造格架和深部地质特征,并与塔里木盆地、准噶尔盆地的地球物理场进行了对比,为油气勘探部署提供了科学依据,拓宽了非地震地球物理信息的应用领域,而且对其它含油气盆地的综合地质与地球物理研究和油气勘探部署也有借鉴作用,同时也有助于区域大地构造和盆地对比研究。因此,本项研究既有构造地质与地球物理理论意义,而且对盆地分析和油气勘探评价也有实际的指导作用。

Abstract: The characteristics of gravity, magnetic and geothermal fields in Qaidam basin are analyzed. According to the information of geophy: sical field, the basin's sedimentary structure, regional structural framework and deep geologic feature are discussed, providing scientife bases for the petroleum ex ploration, widening applied domains of non-seismie geophysical information. These could be as a guide to other oil-gas bearing basins' prospecting and studies in regional tectonics and basinal correlations.

Key words: Qaidam basin, gravity fild, magnetic fild, geothe rmal field, deep geologie feature, regional tetonics
