摘要
欢喜岭油田欢26块和新欢27块是注水开发的低渗透油藏。对于低渗透区块,注入水的水质是影响注水井吸水能力、保持地层压力和油井产量的关键因素。本文根据对储集层敏感性的评价,尤其是对现场注入水水源的分析和室内岩心流动实验的一系列测试,为以欢26块和新欢27块为代表的欢北低渗透油藏的注水开发提供重要的理论依据。
Block Huan 26 and Xinhuan 27 in Huanxiling oilfield are water flooding low permeability reservoirs. Injected water quality is the key factor affecting water absorbing capacity and maintenance of formation pressure and oil production. This study evaluates reservoir sensitivity , tests fluid properties, analyzes injected water, and conducts a series of tests for flow in cores. This paper provides theoretical basis for water flooding in Huanbei low permeability reservoirs like block Huan 26 and Xinhuan 27.
