摘　　要：对于处于开发中后期注水油田,如何提高水驱采收率成为技术攻关要点。本文以L区块为例,在明确注水开发过程中存在问题基础上,开展技术对策研究,主要包括精细刻画剩余油分布规律、优选各套储层开发方式、注水井段细分重组及油井措施挖潜增油等,现场应用取得较好效果,区块日产油量、综合含水、递减率、水驱储量控制及动用程度、水驱最终采收率等指标均得到明显改善,实现剩余可采储量有效动用。For water injection oilfields in the middle and late stages of development,how to improve water drive recovery has become a key technical focus.This article takes Block L as an example,based on clarifying the problems existing in the water injection development process,carries out technical countermeasures research,mainly including fine characterization of residual oil distribution patterns,optimization of various reservoir development methods,subdivision and restructuring of water injection well sections,and oil well measures to tap potential and increase oil production.The on-site application has achieved good results,including daily oil production,comprehensive water content,decline rate,water drive reserve control and utilization degree of the block The final recovery rate and other indicators of water flooding have been significantly improved,achieving effective utilization of remaining recoverable reserves.
