盐家-永安地区位于东营凹陷北部东段,北为陈家庄凸起,南临民丰洼陷、永安镇隆起,区域形态向南倾没。通过对该地区储层的精细描述,明确该地区储层储层发育类型。然后通过地震反射特征分析,进行深度域与时间域地震反射特征对比,认为叠前深度偏资料更准确的反应了砂砾岩体的形态,可以有效的识别砂砾岩体速度陷阱,精细落实砂砾岩体构造,大大提高了圈闭预测精度。
The Yanjia-Yong’an area is located in the eastern part of the northern part of the Dongying Sag, with the northern part of the Chenjiazhuang uplift, Minfeng Sag to the south and Yong’an Town uplift. The regional shape is notched southward. Through the detailed description of the reservoirs in this area, the types of reservoir reservoirs in this area are clearly defined. Then, by comparing the characteristics of seismic reflection and seismic reflection in depth and time domain, it is considered that the prestack depth data more accurately reflect the morphology of glutenite body, which can effectively identify the velocity trap of glutenite body and finely implement the conglomerate body Structure, greatly improving the prediction accuracy of traps.
