摘　　要：(目的意义)绒囊流体自2009年首次应用于磨溪气田老井侧钻水平井以来,密度低于以油水为连续相的工作流体,体系比泡沫更稳定,以及作业后能够提高油气产量、降低产水,被广泛应用于钻井、修井等石油工程的六个领域。但由于业内缺乏系统的应用报道,导致部分从业者仅了解单一领域的应用情况,难以借鉴以往经验解决实际难题并推动绒囊流体技术进步,通过文献统计法预测绒囊流体应用方向,明确其技术热点与潜在价值,促进其更广泛、更高效的工程应用。(方法过程)回顾绒囊流体十年来的现场应用过程,结合文献统计法和时间序列法,用热点率对比过去应用的分布,用待定系统的大小预测未来应用的领域。(结果现象)绒囊流体文章在钻井、修井、压裂、稳油控水、酸化、聚合物驱替领域中的热点率分别为33%、23%、19%、13%、6%和6%,钻井领域热点率较高主要得益于绒囊流体在井壁稳定、防漏堵漏等方面的粘接提高岩石强度特征。利用时间序列法拟合的线性方程斜率在钻井、修井、压裂、稳油控水、酸化、聚合物驱替领域中的线性方程斜率分别为-0.20、-0.10、0.11、-0.05、-0.09和-0.10,只有压裂是正值。反映目前石油工程的工作重点,也明确了绒囊流体在压裂领域具有较大的发展潜力。(结论建议)文献统计定量化方法,不仅克服传统方法识别热点领域多依赖经验,准确性和科学性较弱的问题,还指明了文献综述的一种方法,为研究者提供一种预测未来发展方向的可选择途径。Since it was first used in sidetracking horizontal wells of old wells in Moxi Gas Field in 2009,the working fluid with density lower than oil-water as the continuous phase,the system is more stable than foam,and it can increase oil and gas production and reduce water production after operation.It is widely used in six fields of petroleum engineering,such as drilling and workover.However,due to the lack of systematic application reports in the industry,some practitioners only understand the application situation in a single field,making it difficult to learn from past experience to solve practical problems and promote the progress of velvet sacfluid technology.By using literature statistical methods to predict the application direction of velvet sac fluid,clarify its technical hotspots and potential value,and promote its wider and more efficient engineering applications.Reviewing the field application process of velvet sac fluid over the past decade,combined with literature statistics and time series methods,comparing the distribution of past applications using hotspot rates,and predicting future application areas using the size of the undetermined system.The hot spot rates of velvet sac fluid in the fields of drilling,well repair,fracturing,oil stabilization and water control,acidification,and polymer displacement are 33%,23%,19%,13%,6%,and 6%,respectively.The high hot spot rate in the drilling field is mainly due to the adhesive properties of velvet sac fluid in wellbore stability,leak prevention and plugging,which improve rock strength characteristics.The slope of the linear equation fitted by time series method in the fields of drilling,well repair,fracturing,oil and water stabilization,acidification,and polymer displacement is-0.20,-0.10,0.11,-0.05,-0.09,and-0.10,respectively,with only fracturing being positive.Reflecting the current focus of petroleum engineering work,it also clarifies the significant development potential of capillary fluid in the field of hydraulic fracturing.The quantitative method of lit
