柴达木盆地第四系生物气的勘探历程与储量现状

Exploration Courses and Reserves State of Quaternary Biogas in Qaidam Basin

以储量研究为主线,以地质认识为重点,通过对不同时期研究认识和勘探思路的阐述,展现了勘探对象由简到繁、从地面构造走向潜伏构造,地质认识由浅到深、从分析现象走向追求本质,储量研究由粗到精、从定性认识走向定量评价,储量规模由小到大、从小型气田走向大型气区的发展过程,对类似沉积盆地的油气勘探和储量研究工作具有积极的借鉴和指导意义。

This paper highlights the reserves study and the geological understanding of Qaidam basin, reviews the consideration and thoughtway for petroleum exploration in different periods, displaying the development courses from the simple to the complex targets for exploration, from the outcrop to the buried geological structures, from the superficial (phenomenon) to the deep (essence) in understanding, from imprecise to precise in reserves study, from qualitative to quantitative assessment, from small to large amount of reserves, and from small-sized gas pool toward large-sized gas province. The study has an active and significant value for reference and guidance to the petroleum exploration and reserves study of other similar sedimentary basins.
