摘要
在地震和地质条件复杂地区,利用纯地球物理方法进行储层预测,由于受到地震资料品质和预测方法多解性的影响,使得预测精度成为制约地震勘探开发的关键。为此,提出了相控储层预测技术,即利用地震相和沉积相控制地震储层预测。给出了相控储层预测技术的基本原理——综合利用地质、物探和测井资料,从地震相出发寻找储层识别模式,利用沉积相(有利地震相)控制地震储层预测。在大牛地气田D井区,应用相控储层预测技术对盒3段和山1段的有利储层分布范围进行了预测,预测结果与井的符合率在90％以上。
Reservoir prediction under the constraint of seismic or sediment phase is proposed from the view of combination of geology and geophysics in order to improve the accuracy of reservoir prediction. The sediment and seismic phase is used to control the results of reservoir prediction. The method improves the traditional methods depending on the algorithm. The accuracy of reservoir prediction in DND gas field is improved greatly by this method. The prediction result has a consistent rate of 90% with the real well data.
