摘　　要：“十三五”期间,长庆油田累计实施6.4万井次油井间抽作业,抽油泵效、系统效率等关键机采指标保持了低渗透油田较好水平。为了适应数字化转型、智能化发展趋势,克服油井传统人工间抽方式的局限性,在已有完备的物联网配套基础上,探索形成适用于长庆油田的智能间抽技术模式,以较低成本对间抽井进行集中管理和控制。研发油井间抽软件平台,实现油井生产制度确定、优化调整、启停控制、指标监控4个方面的智能化。间抽技术智能化促使间抽制度的制定依据更加合理,技术效果更加明显,同时降低了间抽作业对人工的依赖,降低了人力成本。Changqing Oilfield has conducted intermittent oil extraction service cumulatively for 64000 well times during the 13th Five-year Plan period.The key indexes of artificial lifting,such as pumping efficiency and system efficiency,were kept at a relatively high level in terms of a low-permeability oilfield.To meet the development trends of digitalization and intelligence and break the bottleneck of traditional artificial intermittent oil extraction,an intelligent intermittent oil extraction technology suitable to Changqing Oilfield was developed on the basis of the established Internet of things so that the intermittently-extracted oil wells could be brought under concentrated management and control at a relatively low cost.The software platform for intermittently-extracted oil wells was studied and developed to bring about intelligence in four areas–determination of production system for oil wells,optimization and adjustment,control over turn-on/turn-off,and supervision of indicators.Thanks to the intelligent intermittent oil extraction technology,the basis for formulation of the intermittent oil extraction system became more reasonable while the technological results were more prominent.Meanwhile,the intelligence technology also reduced dependence of intermittent extraction service on manpower and cost of workforce.
