摘要
为了弄清也门69区块侏罗系上统地层的沉积特征,评价其潜在的含油气性,运用了录井、测井及地震相分析等分析手段,分析了区内上侏罗统的地层划分、岩性特征、沉积环境及沉积相等。认为上侏罗统主要属滨浅海—半深—深海沉积环境,扇三角洲前缘环境次之,沉积特征可划分为深海槽盆相、槽盆边缘斜坡相、半深海相、陆棚混积相、滨海潮坪相、扇三角洲前缘相及蒸发泻湖等相。同时认为上侏罗统自身具有较好的生储盖组合条件,具有较好的油气勘探前景。
For making clear Yemen 69 block jurassic upper series stratigraphic depositional feature, evaluating its potential oil and gas bearing character, by the exercise of logging, well logging and seismic facies analysis, this paper analyzes instrument, Upper Jurassic stratigraphic division ,lithologic characteristic, depositional environment and depositional faices in the area. Upper Jurassic chiefly belonges to shore shallow sea-bathyal environment-deep-seated deposit environment,the fan-delta front environment takes the second place.These environment could be divided into oceanic trench basin facies, gutter basin fringe slope facies, bathyal facies, shelf mix-accumulated facies, offshore tidal-flat facies, the fan-delta front facies and evaporation lagoon isofacies .At the same time we think Upper Jurassic itself can possess better source-reservoir-caprock association condition, so it will possess better oil and gas exploration perspective.
