摘要/Abstract

摘要： 利用模拟实验数据,建立并标定了研究区沙三段泥岩有机质成油、成气的化学动力学模型。由此出发,评价了源区车西洼陷的生排烃剖面,并对生油门限、生油高峰、排油门限的概念进行了深入讨论。在此基础上,对车西洼陷3套可能源岩的生排烃史进行了定量评价,认为潜山区主力油源车西沙三段的排烃期为东营组沉积后的晚近期,这与由包裹体的均一化温度确定的区内流体运聚成藏期完全一致,从而相互佐证了生排烃期和成藏期研究的认识。

Abstract: A chemical kinetic model is developed for calibrating organic matter-generating oil and gas of Sha-3 member shale in Jiyang depression by using data from thermal simulation experiments. The profiles of hydrocarbon generation and expulsion in Chexi sub-sag are analyzed, and the concepts of threshold of oil generation, peak oil generation and threshold of hydrocarbon expulsion are discussed in detail. Based on these, the quantitative evaluation of the history of hydrocarbon generation and expulsion for three possible source rocks in Chexi sub-sag is conducted, indicating that the hydrocarbon expulsion time took place mainly in late or recent period since the deposition of Dongying formation in Chexi Sha-3 member that is the dominant oil sources in buried hill area. This is completely consistent with the period of fluid migration and accumulation determined by inclusion's uniform temperature. Thereby, the cognitions about the periods of hydrocarbon generation, expulsion and accumulation are validated one another.

Key words: Jiyang depression, organic matter, source rock, hydrocarbon expulsion, inclusion
