摘要
精细油藏描述是油田开发最重要的基础工作,贯穿油田开发的始终。开发中后期的精细油藏描述研究内容与开发初期相比,发生了明显变化,体现出重点性、深入性和精细性的特征。将开发中后期精细油藏描述重点研究内容总结为8方面,分别是:小断层和微构造精细研究、高分辨率层序地层学等理论指导下的地层精细划分与对比、沉积微相研究基础上的储层构型表征、储层微观孔隙结构定量评价、储层流体非均质性研究、油藏开发过程中的储层变化规律分析、多点地质统计学等地质建模方法探索和多信息综合剩余油描述技术。开发中后期精细油藏描述应该针对油田生产实践中出现的关键瓶颈问题,开展针对性的重点攻关,为老油田剩余油挖潜和提高石油采收率提供依据。
Fine reservoir description is the most important foundational work and should be going on with the development of oilfield. Compared with the initial stage of oilfield development, the research content of fine reservoir description in the middle and late stages usually changes significantly and reflects the characteristics of emphasis, profundity and accuracy. The key researches on fine reservoir description in the middle and late stages of development are summarized into eight aspects： fine researches on small faults and microstructures, fine stratigraphic division and comparison under the guidance of high-resolution sequence stratigraphy and other theories, reservoir architecture characterization based on sedimentary microfacies, quantitative evaluation of reservoir microscopic pore structure, reservoir fluid heterogeneity, reservoir changing laws during development, geological modeling based on multi-point geostatistics, and comprehensive remaining oil description based on multiple information. Fine reservoir description in middle and late stages should focus on targeted solutions to key bottlenecks arising out of actual oilfield development and try to provide basic data for developing the potential of remaining oil and increasing oil recovery in old oilfields.
