摘要

摘要: 针对前期碳酸盐岩缝洞型油藏探明储量分类评价成果无法满足油藏精细开发及提高采收率工作的需要的问题，以缝洞识别为基础，动静结合，从缝洞单元内储量的有效控制及动用状况出发，把缝洞单元储量分为未控制储量、井控未连通储量、连通难采出储量和连通易采出储量，形成了缝洞单元储量精细分类评价方法。应用缝洞单元储量精细分类评价成果，开展了完善井部署、注采调整及流道调整等综合调整工作，有效提高了储量动用效率和采收率，改善了开发效果。

Abstract: The previous classification and evaluation results of proven reserves of carbonate fracture-cavity reservoirs cannot meet the needs of detailed reservoir development and oil recovery improvement. Based on the identification of fracture and cavity, using both static and dynamic methods, we proposed a method for the detailed classification and evaluation of reserves in fracture-cavity units in view of the conditions of reserve effective controlling and producing. The reserves of fracture-cavity units were classified into uncontrolled, well controlled but unconnected, connected but difficult-to-produce, and connected and easy-to-produce reserves. The results were applied to a comprehensive strategy such as completed well deployment, injection-production adjustment and flow channel adjustment, which effectively improved production efficiency and development effect.
