| 摘 要： | 本文通过对塔中地区现今工业性油气、稠油及储层沥青的微观今貌特征的研究,结合宏观地质背景,探讨了塔中地区油气成藏及演化模式。研究表明,本区现今油气藏主要形成于喜山成工藏期,而早期成藏的油气因受不同程度的破坏仅以储层沥青和氧化残留油的形态保存下来。来自西北方向海相为主的混源油和来自东北方向海相为主的凝析气、于气形成了现今的油气藏。

| Abstract: | Based on a combination of the microcosmic characteristics of present industrial oil and gas,viscous crude oil and reservoir bitumen,and the macroscopic geological settings in the middle area of Tarim basin,the authors studied the models for petroleum pool-forming and evolution in that region. It is indicated that the present oil reservoirs there had formed mainly in the Himalayan pool-forming stage,however,the oil and gas in the early-formed pools were preserved only in the forms of reservoir bitumen and redox residual oil,as they being damaged to different extents. The present oil/gas reservoirs mainly consist of marine oils of miscible sources from the northwest and marine condensate gas and dry gas from the northeast. |
