摘要:

以《中国石油地质志》编撰为契机,在系统梳理准噶尔盆地石油地质理论、勘探领域及勘探成果的基础上,通过准噶尔盆地勘探历程回顾和钻井、地震、储量等历史数据分析,将准噶尔盆地勘探历程划分为南缘地面地质调查与钻探(1954年以前)、克拉玛依油田发现和扩展(1955—1977年)、东部油气田勘探战略展开(1978—1989年)、腹部沙漠油气田快速突破(1990—2002年)和盆地富烃凹陷规模发展(2003年至今)5个阶段。以油气勘探各阶段重大勘探成果和里程碑式的勘探事件为依据,系统总结了各个阶段的勘探启示以及对勘探产生重要影响的油气成藏模式:逆掩断裂带构造含油模式、源外沿梁断控阶状成藏模式、源内自生自储型火山岩成藏模式、凹陷区源上扇控大面积成藏模式和南缘上、中、下3套成藏组合模式,期望对以后勘探工作具有启迪意义。

Abstract:

To write the book of Petroleum Geology of China, first we summarize the petroleum geological theory, exploration targets and results, review the exploration history and analyze the drilling, seismic, reserves and other historical data, then divide the exploration history of the Junggar basin into five stages — surface geological survey and drilling in the southern margin (before 1954), discovery and expansion of Karamay oilfield (1955-1977), strategic development of eastern oil and gas fields (1978-1989), fast breakthrough to desert oil and gas fields in the hinterland (1990-2002) and large-scale development of hydrocarbon-rich sags (2003-), and finally based on the important exploration results and milestone data of all stages, point out the exploration enlightenment and accumulation models that have important influences on exploration, including structural oil-bearing model in overthrust fault zones, large-area above-source and fan-controlled accumulation model in sags, stepped outer-source, along ridge and fault-controlled accumulation model, inner-source self-generation and self-preservation accumulation model of volcanic rocks, and accumulation models with upper, middle and lower assemblages in the southern margin. These findings are expected to have important enlightenment for future exploration.

Key words: Junggar basin, exploration history review, exploration stage division, accumulation model, exploration enlightenment
