摘　　要：老君庙油田目前已进入特高含水采油期,剩余油难以得到有效驱替。分析评价老君庙L油藏地质开发特征和流体性质,认为老君庙L油藏较适宜采用泡沫复合驱方法提高采收率。在完成试验区井网建设、先导试验井组优选、油藏工程研究、驱油剂体系研究评价与优化的基础上,通过开展单井试注,明确了泡沫复合驱油具有较好的注入能力和驱油性能,配注工艺、生产组织与技术管理能够满足矿场试验需要,为先导试验方案优化设计、高效组织实施提供了有益的借鉴。Laojunmiao oi l field ha s entered the high water cut oi l product ion per iod. The remaining oi l is difficult to be effectively displaced. According to evaluat ion on geology development characteristics and fluid properties of Laojunmiao L-reservoi r, it is bel ieved that it is sui table for Laojunmiao L-reservoir to use foam combination flooding method to enhance oil recovery. After the completion of the wel l network construction, pilot testing wel l group optimization,reservoir engineering research,flooding agent evaluat ion and optimization, it is clear that the flooding system has a good injection capaci ty and oil displacement performance in flooding test. Injection technology, production organization and technical management are able to meet field test. It provides reference for optimization design and efficient execut ion of pilot test.
