摘　　要：通过将封隔器多层压裂的投球滑套技术引入到了水力喷射压裂工艺中,在国内外现有的常规水力喷射分段压裂技术基础上创造性地开发出了不动管柱滑套水力喷射分段压裂技术。该工艺结合了水力喷射技术和滑套多层压裂的优点,在不动管柱的情况下,不使用封隔器就能实现分层改造。根据该工艺的特点,对现场实施关键控制技术进行了优化,确保了工艺的成功应用。Through an introduction of pitching sliding sleeve technology in the multi-fracturing of packer to the hydraulic jet fracturing technology,the sliding water jet staged fracturing technology for fixed columns has been creatively developed based on the current conventional water jet staged fracturing technology at home and abroad.Combined with the advantages of water jet technology and sliding sleeve multi-fracturing technology,this technology has realized the staged reform without the use of packers under the situation of fixed columns.Therefore,according to the characteristics of this technology,the key controlling techniques used in the field are optimized,which guarantees the successful application of this technology.
