摘要
从基础资料研究入手,分析了新近系馆上段曲流河沉积砂岩与围岩速度变化的内在规律,提出了砂岩速度低于围岩速度的观点;明确了储层地震反射特征,探索并总结了储层预测、描述、油气检测的新方法,在垦东北部、孤东周边等地区应用,取得了良好效益。
Based on the studies of the fundamental data,the paper analyzes the intrinsic rule of the velocity variety of the upper Guantao Group sandstone which is of meandering river face and the velocity variety of its surrounding rock,concludes the view point that the velocity of the surrounding rock is lower than it of the sandstone,makes clear the seismic reflecting characteristics of the sandstone reservoir,probes into and summarizes the new techniques of reservoir predicting,reservoir depicting and hydrocarbon detecting.The techniques achieved a satisfying benefit in its applying in regions of the north Kendong area and the adjacent area of Gudong.
