摘　　要：埕北油田具有原油黏度高、油层渗透能力强和非均质性严重等特点,水驱开发效果差,剩余油储量大。目前,埕北油田综合含水90%,采出程度30%左右,而生产平台工作时间已达到设计使用寿命,急需高效、快速的开发技术。针对埕北油藏地质、流体性质和开发现状,利用室内仪器检测和理论分析方法,开展了聚合物筛选和聚合物性能评价,利用模糊综合评判方法对聚合物进行了优选,推荐使用中国石油大庆炼化公司生产"抗盐"和"超高"部分水解聚丙烯酰胺。In Chengbei Oilfeld,oil viscosity was high,permeability of reservoirs was high and anisotropy of reservoirs was serious,so the water drive development effect was not good and remaining oil reserves was much. At present, water cut of Chengbei Oilfield was about 90 % , and degree of oil recovery was 30 % , working hours of production platform has reached the design life, and advanced development technology with high efficiency was in urgent need. Taking reservoir geology, fluid property and the current development situation in Chengbei Oilfield into consideration, selection of polymer and polymer performance evaluation was carried out using indoor detection and theoretical analysis and polymer was optimized by fuzzy comprehensive evaluation method.
