本文针对大民屯凹陷构造复杂、薄互层储层横向变化快等特殊地质条件,应用精细地质分析、属性分析、地震相、测井相、沉积相分析、多井约束反演等技术对大民屯凹陷西斜坡Es4段岩性油气藏进行了整体解剖,有效地识别了地下复杂地质构造及地震异常反射体,综合岩性解释、定量预测和描述了单层砂岩空间分布及变化规律,在油田的勘探开发中取得了良好的效果。 In this paper, according to the special geological conditions such as the complex structure of the Damintun depression and the rapid horizontal change of thin interbedded reservoirs, fine geologic analysis, attribute analysis, seismic facies, logging facies, sedimentary facies analysis and multi-well constrained inversion are applied to large The lithologic reservoirs in Es4 section of western slope of Minitun Sag were anatomized in an integrated way, and the complex underground geological structures and seismic anomalous reflectors were identified effectively. Comprehensive lithological interpretation was used to quantitatively predict and describe the spatial distribution and variation of single sandstone. Oilfield exploration and development has achieved good results.
