在油藏开发的初期,进行储层特征研究来预测砂体和有效储层的分布规律,由于井网稀疏,井资料的匮乏,所以依靠地震资料进行储层预测,但是地震体资料的分辨率无法达到单砂层的级别,不能相对准确的预测砂体分布,因此应用三维地质建模技术对开发初期的储层根据沉积相模型约束和地震属性预测结果通过参数的设定进行确定性模拟,通过变差函数的设定赋予地质意义,比直接使用地震体资料进行储层预测的结果更加符合实际。
In the early stage of reservoir development, reservoir characteristics were studied to predict the distribution of sand bodies and effective reservoirs. Due to sparse well pattern and lack of well data, reservoir prediction was based on seismic data. However, the resolution of seismic data So it can not reach the level of single sand layer and can not predict the distribution of sand body relatively accurately. Therefore, by using 3D geological modeling technique, the initial reservoir is determined by the parameter setting based on the sedimentary facies model constraints and the seismic attribute prediction. The geological significance is given by the setting of variogram, which is more realistic than the result of reservoir prediction by directly using seismic volume data.
