【摘要】 近年来新兴的各种储层预测技术在油气勘探开发中发挥着越来越重要的作用。应用测井约束三维地震反演技术,在廊固凹陷琥珀营油田泉44断块河流相隐蔽油气藏的滚动勘探开发中做了有益的尝试。针对下第三系沙二段纵向上呈多套砂泥岩互层沉积、储层横向变化大、油气成藏规律复杂的地质条件,对薄砂体储层的空间展布进行了测井约束地震反演预测,定量描述了油砂体的分布范围,拓展了新的含油层系并落实了有利的含油气圈闭,为琥珀营油田泉44断块的滚动突破提供了有力的决策依据,也为今后勘探开发柳泉构造带薄砂体隐蔽油气藏提供了新的思路。更多还原

【Abstract】 In recent years, new various reservoir prediction techniques play more important roles in oil and gas exploration and development. The authors applied 3D seismic inversion constrained by well logging in the progressive exploration and development of subtle fluvial reservoir in Hupoying Oil field, Langgu sag. In the second member of Shahejie Formation , many stages of sand-shale sequences in vertical orientation and reservoir of great lateral variation result in complicated regularity to oil pool formation. We quantitatively predicted spatial distribution of the thin oil layer and oil domain using the inversion method and discovered new oil-bearing series and also fixed prospective oil traps, which are not only important decision support for the progressive breakthrough in the district, but also new thought of future exploration and development for subtle reservoir of thin layer in Liuquan structural zone.更多还原
