摘要： 源一盖共控论是在“源控论”的基础上,通过总结塔里木盆地的油气勘探实践经验,参照全球其它地区的资料,依据“系统论”的原理提出来的。其主要内涵是：盖层、特别是区域盖层和烃源一样是油气系统及油气藏形成的前提条件,优质的储集层、畅顺的通道、规模可观的圈闭是在这两个前提条件下才能发挥富集油气的作用。也就是说一个沉积盆地只要具有了活跃而充足的油气源和封闭性良好的盖层,就有希望成为富含油气区。指出塔里木盆地的油气源条件和封盖条件非常优越,可成为我国21世纪石油、天然气工业发展的战略接替区。

Abstract: The source-cap co-control theory is based on "source control theory" and proposed from practical experiences for oil and gas exploration in Tarim basin with reference to another regional data available in the world and principle of “petroleum system theory”. The central idea is that cap rock, especially regional cap rock is the prerequisite for forming petroleum system and oil/gas pool as same as hydrocarbon source rock. And good-quality reservoir rock, unblocked channel and large-scale trap can be brought into play for enrichment of oil and gas under the two prerequisites. That is, once a sedimentary basin has active and abundant petroleum sources and well-confined caps, it is hopeful to become oil and gas enriched area. It is pointed out that Tarim basin has very premium conditions of hydrocarbon sources and confined caps, and will be a strategic succeeding domain in 2000's oil and gas industry of China.
