可膨胀筛管作为一种先进的井下完井工具,特色鲜明,应用越来越广泛。国外威德福公司、哈里伯顿公司、贝克休斯公司和斯伦贝谢公司等知名油服企业进行了深入的研发。通过对比分析四家企业的可膨胀筛管产品及应用特点,结合国内的产品研发现状,为国内的可膨胀筛管的发展提供建议:首先要多投入、早研发,打破国外产品及技术垄断;其次,要研发针对我国地质条件的产品和技术;最后,研发应朝着膨胀工艺简单、材料高性能、产品多样化方向发展。
Expandable screen as an advanced downhole completion tools, distinctive features, more and more widely used. Foreign Weidefu company, Halliburton company, Baker Hughes and Schlumberger companies and other well-known oil service enterprises carried out in-depth research and development. By comparing and analyzing the characteristics of expandable screen products and application features of four enterprises and combining with the current situation of domestic product research and development, we provide suggestions for the development of expandable screen tubes in our country. First, we must invest more and research and develop earlier to break the monopoly of foreign products and technologies. Secondly, it is necessary to develop products and technologies that are geologically targeted at China’s geological conditions. Finally, research and development should be directed toward the expansion process, material high performance and product diversification.
