摘　　要：为了确定低产低效影响因素及挖潜措施潜力,利用灰色关联度进行低产低效井影响因素分析,优选出影响产能的主要因素,结合多元线性回归方法与数理统计理论,建立了X油田油井压裂措施增油量预测模型和堵水井降水量预测模型.有机结合油井降水措施和增油措施的经济界限模型,可以准确预测低产低效井压裂增油潜力及堵水降水增油潜力,误差5%-10%以内,有效指导低效低产井再开发.Inorder to confirmthe influence factor of low yield low-officiency oil nell and espoitation mwasure potertial By analyzing influence factor of low-yield low-efficiency oil well with grey relational degree,the principal factors of influencing capacity are optimized,the well fracturing and plugging measure effect enhanced oil prediction model of X oilfield are builded.With oil well dewatering and increased oil measure economic boundaries model,the well fracturing and plugging measure effect enhanced oil production potential is predicted accurately,and accumulated error is within 5%-10%,effectively guiding the potential redevelopment of low-yield and low-efficiency oil well.
