摘　　要：非常规油气资源丰富,开发潜力巨大。但因其渗透率低、渗透阻力大导致水平井单井产量低,难以满足经济开发要求。为提高储层改造效率实现有效增产,中外形成了水平井分段压裂的主体技术。作为水平井分段压裂的新兴技术,套管固井滑套分段压裂具有井眼适应性强、过流面积大、适合大排量压裂的优点。概述了各类套管固井滑套分段压裂工具现状,指出了工艺技术背后的缺陷与难点。通过对各类工具优缺点对比分析,提出了套管固井滑套未来的发展建议。Unconventional oil and gas reserves are abundant and have great potential for development.However,due to its low permeability,high permeability resistance and inferior connectivity,the single well production of horizontal wells is low,which is difficult to meet the requirements of economic development.In order to improve the efficiency of reservoir stimulation and achieve effective production increase,the main technology of horizontal well segment fracturing has been formed at home and abroad.As an emerging technology of horizontal well segmentation fracturing,casing cementing sliding sleeve segment fracturing has the advantages of strong borehole adaptability,large flow area and suitable for large displacement fracturing.The current status was summarized of various casing cementing and sliding casing stage fracturing tools,and pointed out the defects and difficulties behind the technology.Through the comparative analysis of the advantages and disadvantages of various tools,suggestions for the future development of casing cementing sliding sleeves were put forward.
