第8期滕先林.四川威远地区页岩气藏储层纵向可动用程度分析57Analysis of Vertical Producing Degree for Shale GasReservoirs in Weiyuan Area,SichuanTeng Xianlin(Geology Research Institute of PetroChina Great Wall Drilling Company,Panjin Liaoning 124000)[Abstract]The shale gas development practice in Weiyuan area of Sichuan Province in the past eight yearsshows that there is a positive corrrelation between the production of shale gas wells and the drilling rate ofLongyi sublayer,so the target location of horizontal wells in Weiyuan area is preferred in Longyi sublayer.However,due to the thinness of Longyi,sublayer,it is impossible to achieve profitable development only byexploiting the reserves of this sublayer.Therefore,how to accurately obtain the fracture height after stimulatedreservoir volume is crucial to further evaluate the vertical producing degree and remaining gas distribution ofshale reservoirs in this area.However,there is no direct and effective method to obtain the fracture height atpresent.Through direct observation and prediction means such as core analysis and micro-seismic monitoring,production and monitoring data analysis means such as platform producing reserves analysis and fracturingprocess analysis,and simulation means such as numerical simulation and fracturing simulation,the fractureheight of shale reservoirs in Weiyuan area is about 15m after various methods are combined and verified forcomprehensively analyzing and predicting.The vertical produceability layers are Longyi'-Longyin sublayers.How-ever,Longyi sublayer,which is almost unproductive,is the main horizon of remaining gas distribution at pre-sent,and can be selected as the target horizon for the next tridimensional development.[Keywords]shale gas reservoir;fracture height;producing degree;micro-seismic monitoring;platform producingreserves fracturing simulation我国生物燃料发展潜力国际能源暑2023年中期石油市场报告称，随着加快清洁能源转型，未来几年全球石油雪求增幅显著效缓。报告预测，在石化和航空那门强劲雪求的支持下，全球石油雪求2022~2028年将增长6%，达到日均1.057×10bl。但年均雪求增幅将在未来几年放缓。重要原因是，随着电动汽车发展、生物燃料用量增加以及燃料经济性提高，2026年开始运输业石“十四五”时期，我国生物技术和生物产业加快发展，生物经济成为推动高质量发展的强劲动力。生物经济正在勾勒人类社会未来发展的美好蓝图。国际能源署和国际粮农组织的综合研究表明，生物液体燃料能在一定程度上减少温宝气体排放。以生物燃料乙醇为例，2008年以来，根据可再生燃料标准（要求使用的乙醇和其他生物燃料已使美国交通运输温室气体排放减少了9.8×10帆：仅在2021年，生物燃料乙醇的使用就减少了5450x101温室气体排放。我国经过20多年的发展，我国生物燃料乙醇已实现部分汽油替代，为绿色交通提供了支撑。在交通领城应用方面，生物液体燃料具有巨大的发展潜力。以生物柴油为例，它不仅可完全替代普通柴油，而且可在不占用土地、不与人争粮的情况下，通过植物戏废弃物的碳汇形成闭环，进而实现碳排放“零增长”，是降低交通运输领城碳排放直接、有效的手段之一。生物液体燃料作为可再生能源的重要组成部分，可为交通领城碳减排开拓新途径。据预测，从2021年到2030年左右，生物燃料乙醇和生物柴油将是公路运输重要减排方式之一，生物航空燃油也会逐渐在航空领城使用。预计2030年后，生物液体燃料总用量将达到7000x10叶，为交通领城减排二氧化碳的4×10%。（供稿舟丹）(C)1994-2023 China Academic Journal Electronic Publishing House.All rights reserved.http://www.cnki.net
