| 摘 要： | 根据排烃研究的最新成果及煤岩研究的最新进展,认为煤岩中油气运移的主要机理为生烃增压驱动下沿微裂缝的独立烃相排出,含烃饱和度和破裂压力是控制排烃的两个主要因素,据此建立了煤岩微裂缝排烃模型.将它应用到辽河盆地桃园--荣兴屯地区的排烃研究中,获得了较理想的结果,表明该模型是合理的.

| Abstract: | Based on the recent study results of hydrocarbon expulsion and recent advances made in coal study, it is suggested that the main mechanism for oil and gas migration in coal is hydrocarbon expulsion as an independent phase along the microfracture driven by the elevated pressure resulting fromhydrocarbon generation. Hydrocarbon saturation and fracturing pressure are the main controls on hydrocarbon expulsion. The model of hydrocarbon expulsion along the microfracture in coal is then developed, which proved to be reliable and valid while it was applied in the study of hydrocarbon expulsion in Taoyuan-Rongxingtun area, Liaohe basin. |
