准噶尔盆地腹部油气勘探回顾与展望

准噶尔盆地腹部从八十年代初大规模投入油气勘探以来,已取得了丰富的勘探成果,发现了三个中一大型的油 气田以及多个含油气构造。对油气富集规律的认识也由“源控论”飞跃到了“梁聚论”。以准噶尔盆地腹部的勘探历程为 线索,从研究油气运聚特征入手,剖析成功与失利的原因,建立了油气成藏模式,并结合对目前的勘探现状和勘探技术, 以含油气系统理论为依据,提出应继续发挥“源控论”和“梁聚论”的指导作用和今后的勘探方向。

Review and Prospect for Petroleum Exploration in Hinterland of Junggar Basin

Since the early 1980's, when large-scale petroleum exploration activities began in hinterland of Junggar basin, we have got plentiful and substantial results in exploration. Three large- and medium-sized oil and gas fields have been discovered, including many petroliferous structures. The recognition of rules for hydrocarbon enrichment has also emerged a leap to "uplift accumulation theory" from "source control theory". The authors established a model for oil/gas reservoir formation by clues of the exploration course in hinterland of Junggar basin, characteristics of petroleum migration and accumulation as well as reasons for success and failure in this area, and proposed some suggestions for further exploration, based on existing conditions and state of the arts for petroleum prospecting. This paper is, on the basis of petroleum system theory, continuous to support these "theories" as a guide for searching for oil/gas.
