油藏描述技术发展及启示

通过回顾油藏描述的发展并结合油田研究实例,阐述油藏描述的特点和给人们的启示。结果表明:该技术是为解决油气田勘探和开发过程中的生产实际问题而产生的,不断出现的油田开发生产实际问题为其发展提供了驱动力;直接面向复杂油藏"迎难而上",针对具体复杂油藏形成"因油藏而异"的配套技术,依靠技术创新发展解决复杂油藏开发难题;体现多学科联合攻关特点,与其相关学科的理论和技术的发展不断推动了油藏描述理论、方法和技术的发展,依靠学科交叉形成边缘新学科,组成联合攻关小组是该技术获得成功的最关键因素;油藏描述以油藏非均质性表征为核心,以改善开发效果、提高采收率为主要目的,抓住了油田开发遇到的主要矛盾;该技术实用性强,广泛应用于油气田(藏)的勘探、评价和开发各个阶段,应用效果显著,形成"实际难题-技术开发-实际应用-解决难题"的良性发展循环。

Development of reservoir characterization and its stimulation

The features of reservoir characterization were discussed through reviewing reservoir characterization history and oil field real case examples. The results show that reservoir characterization technology was developed and improved in order to solve the production problems in petroleum exploration and development. New technologies were developed in response to complications in individual reservoir problems. Development of related disciplines has advanced the theory and technology, which in turn also leads to development of new disciplines. The multi-discipline collaboration is the key to development of reservoir characterization. Reservoir heterogeneity characterization is the emerging challenge in reducing oil development costs and improving oil recovery ratio. The technology can be widely used in exploration, evaluation and development phases of oil and gas fields. The applications of the technology show that a healthy development cycle of "practical problems-technology development-practical application-solve problems" has come into being.
