摘　　要：随着注水开发的深入，大庆长垣外围低渗透、低丰度、低产油藏的开发矛盾逐渐暴露出来：中高含水区块采出程度高，剩余油分布零散，注水开发调整挖掘剩余油难度大；特低渗透裂缝发育区块含水上升快、产量递减快，控水稳油难度大；超低渗透裂缝不发育区块启动压力梯度大，注水受效程度低，开发调整提高有效动用程度难度大。为此，借鉴大庆长垣喇萨杏油田油藏精细描述及其剩余油分布研究技术思路和方法，结合长垣外围已开发油田地质特征和注水开发特点及开发调整实践，研究形成了包括低渗透油藏分类评价、油藏精细描述、剩余油描述、井网加密调整、注采系统调整及微生物驱油和蒸汽驱油在内的综合调整技术，为外围油田注水开发调整提供了技术支持。Integral adjustment technology for water flooding was developed, including classified evaluation of low- permeability reservoirs, fine reservoir description, remaining oil description, adjustment for infill drilling and injection-production system, as well as MEOR （ microbial enhanced oil recovery） and steam flooding, based on the thoughts and methods for fine reservoir description and remaining oil distribution researches in La-Sa-Xing oilfield in Daqing Placanticline for reference and combined with the geologic features, water flooding characteristics and practical development adjustment. This technology provides technical support for the adjustment of water flooding in peripheral reservoirs.
