Abstract: Shale gas revolution makes exploration of non-conventional oil and gas resources in parallel with conventional oil and gas resources. Meanwhile, it also means a major breakthrough in traditional oil and gas geological and exploration theories. As for non-conventional oil and gas, "sourcing, reservoir, caprock, migration, accumulation and storage" are no longer regarded as guide to understand oil and gas existence. Identification and selection of traps are neither taken as the necessary process in exploration. The mindset for exploration experiences a revolutionary creation. The efforts will be focused on the "sweet spot" with integration of exploration and development at a high level so far as low-degree non-conventional oil and gas distributed in large areas are concerned. Attention should be paid to the characteristics of non-conventional oil and gas exploration and development so as to improve the theories and methods in this area. It is necessary to develop a series of technologies suitable for China's conditions in the efforts to promote the nation's non-conventional oil and gas development.

Key words: shale oil and gas, non-conventional oil and gas, oil and gas geology, oil and gas exploration, exploration process

摘要： 页岩气革命标志着非常规油气已经成为可与常规油气并列的勘探方向,同时也意味着传统的油气地质和勘探理论将要并已经有重大创新性突破。对于非常常规油气而言,不但"生、储、盖、运、聚(圈)、保"的"六字箴言"失去了认识油气赋存的指导意义,圈闭的确定和优选也不再是勘探的必经程序;勘探思路有革命性的开拓创新;对低品位却呈面积性分布的非常规油气,更加关注"甜点"的寻找,勘探开发高度一体化;观念变了,思路变了,方法变了。针对非常规油气勘探开发理论和方法上的特点,需要我们在实践中关注并上升为理论性认识;在推动我国非常规油气发展中要有适应于我国情况的技术创新和配套完善的技术。
