摘要
石油地质学家有可能在思维定势的影响下运用鲍马序列将内潮汐水流形成的砂坝误解释成浊积扇,从而可能导致对油气圈闭要素不恰当地过高估计。系统总结了已发现的内波、内潮汐沉积的成分结构特征、沉积层序、岩相类型及沉积模式,指出了内波、内潮汐沉积对深水油气勘探的指导意义。此外,水道型内波、内潮汐沉积砂体可作为良好的储集层,可与深水背景沉积一起构成有利的地层或岩性圈闭。
Petroleum geologists under the influence of outdated thinking may get misunderstandings of explaining the sand bars formed from internal-tide water flow as turbidite fan by using Bouma sequence,which probably leads to an inappropriate overestimation of essential factors of petroleum trap.This paper reviews the composite structures,sedimentary sequences,lithofacies types and sedimentary models of discovered internal-wave and internal-tide deposits,and points out the effects of the deposits on deep water hydrocarbon exploration.Also,it suggests that the sand bodies in submarine channel internal-wave and internal-tide deposits could be as good reservoirs and form favorable stratigraphic or lithologic traps together with deposits in deep water.
