泌阳凹陷陡坡带砂砾岩体预测

在对泌阳凹陷陡坡带砂砾岩体空间展布预测中,以层序地层学研究为基础,依据古地貌沟扇对应理论,利用地震属性分析技术和地震反演技术,寻找砂砾岩扇体并确定其分布边界.预测结果,在陡坡带边界断层附近发现了新的砂砾岩扇体,在深凹区过渡带发现了浊积砂体,均为有利的油气聚集区,经钻探获得了良好效果,对陡坡带砂砾岩体的勘探起到 较好的指导作用.图3参10

In the prediction of the space distribution of the glutenite body of steep slope zone in the Biyang Sag, seismic attribute analysis and seismic inversion techniques, based on the sequence stratigraphy researches and the corresponding relationship between palaeo-geomorphologic channel and fan, were utilized to determine the glutenite body and its distributing boundary. The prediction result shows that new gutenite bodies are found near the boundary fault of the steep slope, and turbidities bodies are found in the transition zone of the deep depression. They are favorable accumulation areas, and the drillings in the areas have got abundant oil.
