摘　　要：东营凹陷东部古近系与三角洲沉积体系相关的浊积岩油藏广泛分布,具有较大的勘探空间和资源潜力。但随着勘探程度的提高,埋藏深、个体小、厚度薄的浊积岩油藏成为主要勘探对象,受埋藏深度、储层厚度、围岩屏蔽作用及灰质影响等因素控制,浊积岩地震识别难度大。本文总结了3个浊积岩地震识别难点,提供了相应的针对性技术,同时,为了提高浊积岩描述的精度,提出了合理的浊积岩储层描述思路和预测流程,以期对浊积岩油藏勘探具有一定的指导作用。The turbidite reservoirs of the Paleogene System related with and the delta sedimentary system in the east of Dongying Sag are distributed widely, and have greater exploration space and resources potential. The deep, small and thin turbidite reservoirs have become the main exploration targets along with the depeening of the explo- ration. The turbidite reservoirs are difficult to be identified as the factors such as the depth of the buried reservoir, thickness of reservoir, shielding effect of the surrounding rock, and grey matter etc. the paper generalizes three dif- ficulties on the seismic identification of the turbidite reservoir and provides some appropriate techniques to identify the reservoirs. To improve the precision of the turbidite reservoir description, the paper proposes reasonable clues and prediction flow charts of the turbidite reservoir description to guide further turbidite reservoirs exploration.
