摘要
东海西湖凹陷位于浙东坳陷东部,其平湖组海陆过渡相地层中,保留有许多海进潮道砂体,系平湖组主要储层。本文综合西湖凹陷区域地质资料以及平湖组海进潮道砂体的测井资料、岩芯描述,探讨了海进潮道砂体的成因机制及分布、保存受控因素。
Xihu Trough located at the eastern Zhedong Depression, the East China Sea, developed transitional Pinghu Fm. which shows a series of transgressive tidal channels (dominant reservoirs in Pinghu Fm.). Based on regional geological data of Xihu Trough, logs and cores of transgressive tidal channels of Pinghu Fm, this paper discusses the genesis of transgressive tidal channels and these factors influencing the distribution, preservation of these sandbodies.
