| 利用流体包裹体综合分析技术，研究东营凹陷不同构造区带油气成藏方式。结果证明，不同构造区带成藏期古压力及成藏方式具差异性：北部陡坡带沙四段烃源岩上储层油气成藏主要分3期，成藏方式以间歇的幕式充注为主；中央背斜主要分2期，成藏方式以突发式的幕式充注为主；南部缓坡带仅1期，早期成藏方式以持续性充注为主。在凹陷南部缓坡带孔店组的储层中发现沸腾包裹体，分析认为成藏晚期发生过幕式充注，推测在沙四烃源岩下存在新的成藏体系。东营凹陷不同区带成藏模式的确定，可为在高勘探程度地区寻找隐蔽油气藏提供理论依据。 |

| Abstract: |
| The author studied the episodic reservoir-formation of different tectonic zones in Dongying depression with fluid inclusion technology. The results demonstrated that the accumulation period and ancient pressure accumulation mode were different during different tectonic zones. The intermittent episodic reservoir-formation was the dominant pattern for lithologic reservoir in northern steep slope in Dongying depression, the burst episodic reservoir-formation was the dominant pattern in the central anticline zone with fault development, the durative episodic reservoir-formation was the dominant pattern in south slope zone. In addition, the fluid inclusion evidence of episodic reservoir-formation was discovered in early Tertiary. The bubble inclusion was discovered in Kongdian Formation of south slope zone and bubble inclusion was the favorable evidence of episodic reservoir-formation. The high waxy oil of Wangjiagang area was different from the upper source rocks, which indicated that the new accumulation system might exist in underneath source rocks. The result provided a new object for further exploration. The determination of different episodic reservoir-formations in Dongying depression provided theoretic evidence for the search of subtle reservoirs in mature exploration regions. |
