摘要：
随着油田勘探开发的深入，固地质、工程原因导致套变并越来题多，严重制的了油田的开发生产和施改遗。套变
井固并简内通径变小，可能造成机械分压工具无法正常通过、或青通过后工具在套变段存在遇卡风险，在分层压裂中难以实现精细改造。为此，研发了套变并精细分层压裂工具。通过对精细分层压累管程、组合流道结构的喷嘴、多获压裂滑套等关健工具的结构和材质研究，使该压裂工具具有小直径、耐磨蚀、精细分层、适应性强等优点，满足套变并压裂和精细分层的需求。现场应用效果良好，通过精细分层，提高压裂措施改造的针对性，最大程度提高了改造效果，具有进一步推广价值

Abstract: With progresses in oilfield exploration and development, more and more wells encountered casing deformation caused by geological or engineering reasons, which may seriously restrict production and EOR measures. Since diameters of borehole with casing deformation are reduced, mechanical tools for stratified fracturing operation may experience difficulties in passing through. In ad-dition, stuck risks in intervals with casing deformation are high for these tools. Under such circumstances, conventional tools can hardly be used in stratified fracturing to achieve desirable performances. Therefore tools for fine stratified fracturing operation in wells with casing deformation have been developed. Based on detailed study on the structure and material of fracturing string, nozzles in integral flowing channel structure, cluster fracturing sleeves and other key tools, these fracturing tools are determined to have minor diameters outstanding abrasion-resistance performances, high adaptability and other desirable features to fully satisfy demand for fracturing and fine stratification in wells with casing deformation. Field application results are satisfactory. Through fine stratification, EOR perfor-mances can be maximized. In the future, these tools can be applied more extensively
