【摘要】 位于全球特提斯巨型油气构造域东段的青藏高原是我国现今陆上面积最大、油气调查和研究程度最低的地区。尽管近些年来对青藏高原油气地质研究取得了大量成果,但是仍存在诸多尚未解决的基础地质和石油地质问题,从而影响并制约着该区油气资源远景评价。根据特提斯构造域演化、青藏高原大地构造属性、盆地基底以及新生代大陆碰撞、高原隆升对盆地的改造作用,提出了影响该区油气资源远景评价的10个重要问题,并对这些问题进行了讨论分析,指出了该区油气地质调查与远景评价中应进一步深入研究的关键问题。更多还原

【Abstract】 The Qinghai-Tibet Plateau is located in the east part of the Tethys realm that is the largest petroliferous region onshore in China which is under-explored.Because of the special structure,complicated tectonic evolution and badly natural environment,the research level of petroleum exploration in Qinghai-Tibet Plateau is the lowest in China.There are some unsolved problems in the study on basic geology and petroleum.These problems have been and still are the obstacles for further evaluation of oil and gas.Based on the present fact,ten problems about oil and gas evaluation including evolution of Tethys,structural attribute of Qinghai-Tibet Plateau,basement of basin,and influence of Cenozoic continental collision and plateau uplift were discussed.Some key problems to be researched in oil-gas survey and evaluation in this area were pointed out.更多还原
