摘　　要：喇萨杏油田进入特高含水期开采阶段后，针对多层非均质油层的特点及其在多种驱替方式、多套井网开发下的主要矛盾，立足于精细挖潜和综合调整，发展了层系井网调整、单砂体注采关系评价及调整、区块开发效果评价和综合调整等特高含水期开发调整技术。通过对这些技术及应用效果的系统总结与概括，明确了改善特高含水期开发效果的思路和对策，有力地推进了老油田进一步提高采收率的步伐。After La-Sha-Xing oilfield entering into ultra-high water cut stage, regarding to the characteristics of multi-layer heterogeneous reservoir and major contradictions under multiple displacement patterns and multiple well patterns, and aiming at tapping the latent power and for the purpose of integral adjustment, the development and modification technologies were formed and developed, mainly including the well pattern modification for layer system, the evaluation and modification of injection-production system for single sand-body, the development evaluation and integral modification for blocks. Through the systematic conclusion and generalization of these technologies and application effects, this paper presents the thoughts and strategy for improving the development effects during ultra-high water cut stage, which accelerates the process of improving oil recovery in mature oilfield.
