【摘要】 桦甸盆地位于敦密断裂带主干断裂的北侧,是一个半地堑式盆地。受同生控盆断裂的控制,含油页岩段厚度和油页岩单层厚度均由北缘向南缘断裂(F1)方向逐渐增厚。盆地内古近系(下第三系)桦甸组为一个完整的三级层序,油页岩形成于水进体系域和高水位体系域的浅湖—深湖环境中。共发育可采油页岩13层,含油率较高(一般8%~13%),质量较好,具有很好的工业前景。更多还原

【Abstract】 The Huadian basin situated in southern Jilin Province of NE China is a half-graben basin and lies to north of the Dunhua-Mishan faults.The thickness of oil shale-bearing strata and monolayer increase gradually from north to south under the control of the contemporaneity fault（F₁）.The fault also controlled basin filling features of the Huadian basin.The whole sequence of Huadian Formation of Paleogene in Huadian basin comprises a complete 3^rd order sequence.The oil shales within the sequence were deposited in semi-deep to deep lacustrine environments,and were developed during transgressive systems tract and highstand systems tract.In Huadian basin,there are 13 oil shale layers containing high-mobile oil（commonly 8%¹3%）.These high quality oil shales may have the potential for industrial use.更多还原
