2023·11工艺与设备172ModernChemicalResearch当代化工研究脉冲爆燃造缝解堵工艺技术与其现场应用＊王江张雷雷黄磊*张宝劲杜金龙（中国石油集团渤海钻探井下作业分公司河北062552）摘要：目前多数油田进入了低渗透、特低渗透储层的开发阶段，油水井受到不同程度的堵塞污染，地层近井区域的渗透率下降，致使单井产量严重下降。亟需研究出一种消除和碎解射孔污染、堵塞和压实带的技术。脉冲爆燃造缝解堵技术利用火药或火箭推进剂高速燃烧的方式，使井壁地层产生多条径向裂缝，与天然裂缝沟通，提高导流能力。该技术对近井地带的污染、堵塞具有很好的解堵作用，能有效降低表皮系数，提高渗透率，实现增产增注的目的。通过在岔20-55x等井的施工作业，证明了该技术具有良好的造缝解堵效果及应用前景。关键词：脉冲爆燃；造缝解堵；推进剂；高能气体中图分类号：V512文献标识码：ADOI：10.20087/j.cnki.1672-8114.2023.11.053ResearchandApplicationofPulseDetonationCrackingandBlockingRemovalTechnologyWangJiang,ZhangLeilei,HuangLei*,ZhangBaojin,DuJinlong(CNPCBohaiDrillingDownholeOperationBranch,Hebei,062552)Abstract：Atpresent,mostoilfieldshaveenteredthedevelopmentstageoflowpermeabilityandultra-lowpermeability.Oilandwaterwellshavebeenblockedandpollutedtovaryingdegrees,andthepermeabilityofthenear-wellareaoftheformationhasdecreased,resultinginaseriousde-clineintheproductionofsinglewells.Itisurgenttodevelopatechnologytoeliminateandbreakperforationpollution,pluggingandcompactionzone.Thepulsedeflagrationcrackmakingandpluggingremovaltechnologyusesthewayofhighspeedcombustionofgunpowderorrocketpropellanttomakemultipleradialfracturesinthewellboreformationcommunicatewithnaturalfracturesandimprovetheconductivity.Thistechnologyhasagoodeffectonremovingthepollutionandpluggingnearthewell,effectivelyreducingtheskinfactor,improvingthepermeability,andachievingthepurposeofincreasingproduction.ThroughfieldapplicationinCha20-55xandotherwells,ithasbeenprovedthatthistechnologyhasgoodeffectoffractureandpluggingremovalandapplicationprospect.Keywords：pulse-detonation；slottingformingfissure；propeiiant；highenergygas前言目前，国内各大油田的开采普遍进入中后期[1]，老...
