恩平凹陷第三系文昌组异常岩性体特征
摘要
对珠江口盆地恩平凹陷下第三系文昌组大套暗色泥岩中的"异常岩性体"的分布、岩性、地质背景和地震响应等特征进行了研究,结果表明该异常体为沉积浊积体。对其形成模式和保存条件进行了探讨,运用地震和测井技术研究了其气测异常、高压异常、地温梯度小、AVO属性异常和层位下拉等现象,分析了该沉积浊积体的含油气性。珠江口盆地恩平凹陷文昌组泥岩是本区的主要油气源岩,有机质丰富,充足的油源为浊积体成藏奠定了物质基础。该浊积砂体是有利的勘探目标。
The characteristics of distribution,lithology,geology and seismic response of the lithology anomalous body in the Tertiary Wenchang Formation of Enping Sag in Pearl River Mouth Basin were studied.The lithology anomalous body is a turbid sediment body.The phenomena of gas measurement abnormity,high-pressure abnormity,smallness of ground temperature gradient,AVO attribute abnormity and stratum descend of the anomalous body were analyzed by using the seismic and log technologies.The Tertiary Wenchang Formation of Enping Sag in Pear River Mouth Basin has rich organic matters and is the main oil-gas source.The anomalous body is favorable exploration area.
