在油田开发初期, 隔夹层的描述仅是通过隔夹层密度和隔夹层频率来表征, 但进入开发中后期的油田调整阶段, 隔夹层的定量描述技术显得尤为重要, 特别是井间精确预测技术尤为关键。该文以鄂尔多斯盆地B 油田厚层砂岩研究为例, 通过岩电关系分析和测井识别模式, 并应用随机储层建模技术, 建立了三维精细隔夹层分布模型, 在指导油田内部挖潜调整、提高水驱储量动用程度方面发挥了积极作用。

At the early stage of the oilfield development, it only used density and frequency to describe the interbeds. The quantitative description method, especially the inter-well prediction method for interbeds becomes significant in the later period. Taking the thick sandstone reservoir in Ordos Basin as an example, the recognition method for interbeds is analyzed. The stochastic modeling techniques combining with lithology and logging are applied to establish a 3D interbed model. This model takes a significant part in guiding the potential excavation and increasing oil recovery.
