摘　　要：本文记述了首次在西准噶尔布龙果尔地区发现的古油藏基本地质情况,探讨古油藏产出的地质层位及时代归属,对古油藏油源问题进行了初步分析,在此基础上提出古油藏成藏预测模式。认为上古生界古油藏所在的和布克河组一段地质时代为晚泥盆世法门期,中生界古油藏产出层位为下侏罗统八道湾组;推断和布克河组古油藏油源可能来自中泥盆统呼吉尔斯特组上亚组陆相烃源岩生成的油气,八道湾组古油藏油源可能来自上古生界海相烃源岩生成的油气;布龙果尔地区具有多期多源油气成藏特点,断层、不整合面和裂隙是油气运聚和调整的主要通道;和布克河组是北疆地区目前发现的最古老含油层系,对拓展该区油气勘探领域具有十分现实的指导意义。This study described the basic geologic situation of ancient reservoir discovered firstly in Bulongguoer area of West Junggar Basin.Based on the research of the geologic horizon,age,and oil source of the ancient reservoir,a prediction model for ancient reservoir formation was established here.The geologic age of the ancient reservoir of Neopaleozoic and Bukehe Formation was identified as Famen Stage of Late Devonian,and the production pay of Mesozoic ancient reservoir was determined as Badaowan Formation of Lower Jurassic.It can be inferred that the oil sources of ancient reservoir of Hebukehe Formation probably came from the generating oil and gas of continental source rocks of Shangya Member of Hujiersite Formation of Middle Devonian,and the oil sources of ancient formation of Badaowan Formation might came from the generating oil and gas of Neopaleozoic marine source rocks.The play of oil and gas in the Bulongguoer area is characterized by multi-stages reservoir formation.Faults,uncomformities and fractures were the main passages for migration and adjustment of oil and gas.The Hebukehe Formation is the oldest oil-bearing series found yet in north Xinjiang area,and this will give practical guide to expanding the oil and gas exploration domains in this area.
