摘要
注水是目前油田开发中应用最广泛的二次采油技术,也是目前高产稳产的重要手段。但在油田注水过程中,由于各种原因造成注水地层吸水能力下降,影响了油田注水开发的效果。本文利用等级权衡法和灰色模糊综合评判法对东辛油田2002年～2005年注水井206井次解堵措施进行了分析,并与实际应用后的效果进行了对比,符合率高,可以用于预测处理措施的效果。对实现东辛油田注水井处理措施决策的及时化和科学化、提高工作效率与工作质量具有重要的指导作用。
Water flooding is the most popular technique of secondary oil recovery and important method for high and stable production.However,the descendent injectivity influences development result during the process of waterflooding.In this paper,the applications of field are analyzed based on grade weighing and fuzzy-gray judgment,results of the calculation are basically identical with those of the application.Therefore scientific measurements can be made in time,and efficiency and quality of work can be improved.
