文明寨地区明一块单砂体地震描述方法探讨
|
摘要
文明寨油田明一块是重要开发区块之一,针对该区目的层沙二下亚段砂岩储层单层厚度薄、横向变化大、薄砂层难预测的特点,通过地震属性敏感性分析、多种地震属性综合应用、定量分析刻画砂体等方法,描述了厚度5m以上单砂体井间变化特征,取得了较好的效果。
Block Ming1 of Wenmingzhai oilfield is one of the important development block,For the target zone S2L sandstone reservoir's characteristics of thin single-layer thickness,Large lateral changes,difficult to predict the thin sand,through the seismic attribute sensitivity analysis,a variety of integrated application of seismic attributes and quantitative analysis to portray the sand body and other methods,describes the thickness of 5 meters or more of the variation in a single sand body well and achieved good results.
