陕甘宁盆地西南缘由于处于多个不同大地构造单元交接部位,早就引起人们重视。近年来,由于矿产普查的开展,积累了一些资料;一九七八年,作者在指导西北大学石油及天然气专业学生毕业实践过程中,又在该区作了地质调查,获得了一些粗浅认识。本文试图应用地质力学理论对本区的构造体系与含油气的关系进行讨论。 在成文过程中,应用了长庆油田地调指挥部综研队、国家地质总局第三普查勘探大队、146煤田队等单位部分地质资料,在此深表谢意。
The southwestern margin of the Shanxi-Gansu-Ningxia basin has long drawn people’s attention because it is in the junction of many different tectonic units. In recent years, due to the development of mineral census, some information has been accumulated. In 1978, when guiding the graduation practice of petroleum and natural gas students at Northwestern University, the author made geological surveys in the area and gained some superficial understanding. This paper attempts to apply the theory of geomechanics to discuss the relationship between tectonic system and oil-bearing gas in this area. In the written process, the application of the Changqing Oilfield Geological Command Research Institute, the Third National Geological Survey census Brigade, 146 coal field units and other units of some geological data, in this deep gratitude.
