| 摘 要： | 砂砾岩体为近物源、快速堆积近岸水下扇沉积,扇体厚度大,横向变化快,巨厚砂砾岩体内部精细地层划分对比为勘探难点.通过三维地震资料时频分析技术,砂砾岩体内幕岩性划分结果与岩心资料、成像资料吻合率较高,为该区厚层砂砾岩体内部地层精细划分与对比提供可靠地质依据,对隐蔽油气藏勘探具良好实用性及应用前景.

| Abstract: | Sand-gravel rock body is a kind of near shore sub-sea apron deposit with characteristics of close source,quick accumulation,heavy thickness and rapid late ralvariation.The technology for correct division and comparison of the strata was inadequate and immature in the past the subdivision and comparison of the inside of the thick sand-gravel rock body is a difficulty for oil geologic research of such reservoirs.Therefore,the geologic strata layer preface which aims at a rock oil to hide identifies a difficul... |
