摘要
辽河油区套管开窗侧钻井平均寿命仅2a左右,侧钻井寿命短一直是制约该项技术发展和推广的瓶颈。全面提高侧钻井固井质量,延长油井寿命,已成为油田中后期开发的迫切需要。本文在辽河油区侧钻井固井质量调查的基础上,分析影响侧钻井固井质量的主要因素,剖析其固井施工难点,全面阐述提高侧钻井固井质量的方法和技术措施,对保证固井质量和减少施工风险具有积极作用。
The average life of casing side-tracking wells is about 2 a in Liaohe oil province. Short life of side-tracking well restricts the development and popularization of this technology. Improving cement quality of side-tracking well and the life of oil well has been an urgent need in production tail period. Based on cement quality investigation for side-tracking wells in Liaohe oil province, this paper analyzes the main factors affecting cement quality, difficulties of cementing operation, and also expatiates the methods and technical measures for improving cement quality. This is helpful for ensuring cement quality and reducing operation risk.
