摘要
为降低水泥浆受污染程度,提高钻井效率及固井质量,近几年不断有新型胶塞被研制应用。介绍了国外4种新型固井胶塞,即,套管固井防转固井胶塞、尾管固井多胶塞系统、尾管悬挂-分级注-封隔器联合固井4塞系统、深海套管固井海底释放塞系统的结构特点和工作原理,可为国内胶塞的研制、改进和创新提供参考。
Recent years, many new patterns of plug have been designed and applied to minimize the contamination of cement slurry, improving drilling efficiency and cement job quality. In this paper, Four different patterns of plug for cementing will be introduced and analyzed for future study and improvement, including anti-rotation plug for casing; liner-wiper plug for casing; liner hanger-multi staged cementing-packer four-plug system; subsurface release cementing plug system.
