油气田进入开发阶段后,为了优化开发方案,提高开发效率,往往需要在较短时间内进行快速储层预测。利用地震属性和储层物性的相关性筛选出对某一储层物性敏感的地震属性,建立其与储层物性之间的关系,把井点储层物性外推到井间,能够快速精确地描述油藏地质特征变化,确定储层的属性分布。本文以A油气田的A1气藏为例介绍了利用地震属性进行快速储层预测的关键点和取得的良好应用效果,证明该方法在本地区具有广泛的应用前景。
After the oil and gas fields enter the development stage, in order to optimize the development plan and improve the development efficiency, rapid reservoir prediction is often required in a short period of time. By using the correlation between seismic attributes and reservoir physical properties, seismic attributes that are sensitive to the physical properties of a reservoir are screened out to establish their relationship with reservoir physical properties. Extrapolation of physical properties of well points to wells can quickly and accurately Describe the changes in reservoir geological features and determine the distribution of reservoir properties. In this paper, the A1 reservoir in A field is taken as an example to introduce the key points of quick reservoir prediction by using seismic attributes and the good application results obtained. It is proved that this method has a broad application prospect in this area.
