现代油藏描述技术及其应用

油藏描述就是对油藏的各种参数进行三维空间的定量描述和表征,也就是要建立反映油藏构造、沉积、成岩、流体等特征的三维油藏地质模型.油藏描述技术的发展和应用使我国油藏研究由定性和半定量走向定量化,由传统的油藏地质研究转入多学科一体化综合的系统研究.但是,如何针对不同勘探、开发阶段我国陆相高度非均质复杂油藏进行描述,仍然是对我国石油地质工作者的一种挑战.在近十年的油藏描述实践中,通过对胜利、大港、辽河、中原、华北等油田的油藏进行描述,逐步形成了具有中国陆相油藏特色的油藏描述技术路线,提出了一些新观点、新技术和新方法.并将其用于指导油藏描述研究.实践表明,这些理论、方法和技术,在油田勘探与开发的早期可预测油气的富集区、高产区,降低成本,提高勘探成功率;在油田的开发阶段,则对油田开发先导实验区的选择,开发方案的制定、调整、油田的综合治理具有指导意义,并能从根本上改善油田的开发效果,提高采收率.

THE MODERN RESERVOIR DESCRIPTION TECHNIQUE AND ITS APPLICATION IN CHINA

The aim of reservoir characterization is to bulid accurate 3-D reservoir models which reflect the reservoir parameters distribution,structure,sedirnentary,diagenesis and fluids distribution through integrated and multi-disciplinary approaches.The development and application of reservoir characterization in China has made a great progress since 1980s.However,due to extreme reservoir heterogeneity,reservoir characterization still remains as greatchallenges.After near ten years reservoir characterization of different phase,type reservoirs in China,some new methods and new theories are put forward and are applied to direct reservoir studies.Practices show that these theories and methods are of value to reservoir modeling and greatly enhance the exploration and reservoir development.
