页岩油作为一种重要的非常规资源类型,拓展了油气勘探开发的新领域。中国东部断陷盆地古近系湖相泥页岩分布范围广、有机质丰度高、厚度大、埋藏较浅、普遍处于生油高峰阶段,具有巨大的页岩油资源潜力。在与北美典型页岩油产区对比的基础上,对中国东部断陷盆地古近系页岩油地质条件进行综合分析,根据富有机质泥页岩的沉积相带、岩石组合、储集空间类型、烃源条件等特征,将页岩油藏划分为深凹区纯泥页岩型、盐间型(盐间高压泥页岩裂缝型、盐间泥页岩夹薄砂岩裂缝型、盐间泥质云岩裂缝型)和泥页岩夹脆性层型(泥页岩夹薄砂岩型、泥页岩夹灰岩型、云质泥岩夹白云岩型)3大类页岩油藏类型,并对其分布特征进行了探讨。在此基础上,对东部断陷盆地古近系页岩油的勘探潜力进行了初步分析,并预测了页岩油有利区。
頁巖油作為一種重要的非常規資源類型,拓展瞭油氣勘探開髮的新領域。中國東部斷陷盆地古近繫湖相泥頁巖分佈範圍廣、有機質豐度高、厚度大、埋藏較淺、普遍處于生油高峰階段,具有巨大的頁巖油資源潛力。在與北美典型頁巖油產區對比的基礎上,對中國東部斷陷盆地古近繫頁巖油地質條件進行綜閤分析,根據富有機質泥頁巖的沉積相帶、巖石組閤、儲集空間類型、烴源條件等特徵,將頁巖油藏劃分為深凹區純泥頁巖型、鹽間型(鹽間高壓泥頁巖裂縫型、鹽間泥頁巖夾薄砂巖裂縫型、鹽間泥質雲巖裂縫型)和泥頁巖夾脆性層型(泥頁巖夾薄砂巖型、泥頁巖夾灰巖型、雲質泥巖夾白雲巖型)3大類頁巖油藏類型,併對其分佈特徵進行瞭探討。在此基礎上,對東部斷陷盆地古近繫頁巖油的勘探潛力進行瞭初步分析,併預測瞭頁巖油有利區。

Shale oil is one of the important unconventional petroleum resources ,and its exploration and development has greatly expanded the traditional domain of the industry .The lacustrine shale in the faulted basins of East China has been considered as having great potential for shale oil based on the facts that it has large coverage ,high organic matter content , and considerable thickness matched well with shallow buried depth , and that most of it is still within the oil-generating peak stage .Based on comparison with the typical shale oil producing plays in the US ,the paper analyzes geological condi-tions of shale oil in these basins in accordance with their sedimentary facies belt , lithology combination , reservoir space types ,hydrocarbon source condition of the organic-rich mudstone and shale .Based on the results ,the paper explores char-acteristics of these reservoirs and classifies three main types of shale oil reservoirs ,i.e.pure shale reservoir in deep de-pression ,shale reservoirs within salt layers , and shale reservoirs with thin brittle interbed such as thin sandstone , lime-stone and dolomite .A preliminary analysis of the exploration potential for shale oil in these basins is also carried out and favorable zones for its exploration are identified .
