高18块为高升油田稠油区块,经历了天然能量、蒸汽吞吐和注水开发三大阶段,目前处于低速开采阶段,2011年以来,以沉积学、油藏工程、数值模拟等学科和技术为指导,综合运用岩心、测井、化验分析、生产动态等资料开展研究工作。通过对静态的地质研究结果与动态生产资料相结合,开展储层特征研究,进一步明确剩余油分布特征。为二次开发方案的设计提供坚实的技术基础,并最终达到提高油藏动用程度,提高采收率的目的。
High 18 is a heavy oil block of Gaosheng Oilfield. It has undergone three major stages of natural energy, steam stimulation and water injection development. It is currently in a low-speed exploitation stage. Since 2011, with the disciplines and technologies of sedimentology, reservoir engineering and numerical simulation as Guidance, integrated use of core, logging, laboratory analysis, production dynamics and other information to carry out research work. Through the combination of static geological results and dynamic production data, reservoir characteristics are studied to further clarify the remaining oil distribution characteristics. This will provide a solid technical foundation for the design of the secondary development program and eventually achieve the purpose of improving reservoir utilization and oil recovery.
