油井压裂是油田重要的增产措施,如何提高压裂井质量,保证压裂效果,是提高油层动用程度,提高油田最终采收率的根本保障。本文从生产实际出发,认真分析了由于地质因素、施工质量等方面产生压裂增油低效井的原因,论述了针对不同原因,改善低效井的方法,并在有关选井、选层标准的提出界定标准,对高效益开发油田具有借鉴意义。
Oil well fracturing is an important stimulation measure for oilfields. How to improve the quality of fracturing wells and ensure the fracturing effect is the fundamental guarantee to increase the utilization of oil layers and increase the ultimate oil recovery. Based on actual production, this paper carefully analyzes the reasons for the inefficient fracturing and oil-enhancing wells due to geological factors and construction quality, and discusses the methods of improving inefficient wells for different reasons. In addition, Of the proposed criteria for the development of high efficiency oilfield with reference.
