摘　　要：井底酸化是油井增产、水井增注的重要措施。理论上分析了现场部分油水井酸化后，油井产液量下降、注水井注水量下降的原因。提出了防止酸化失效的措施，并列举了实例。Bottom-hole acid treatment is an important measure to stimulate injection wells and production wells. Theoretical analysis is made on the cause of the decline of fluid production and water injection amount after acid treatment prohibition, and examples are given.
