摘　　要：安塞油田数字化油田的建成，实现了对采油井示功图和光杆载荷的实时监控和采集．在运用油井数字化功图和载荷曲线中发现，油井光杆载荷的变化与动液面变化有一定的对应关系．根据油井光杆载荷变化计算油井动液面，建立油井数字化液面监控程序；同时结合油井井筒工况的实时采集，有效判断油井井筒是否生产正常，及时发现问题油井，保障油田正常生产。该项技术的应用，为后期利用油井数字化液面监控系统代替人工测试提供了理论依据，减轻了劳动力，可实现油井基础资料录取的智能化，提升油田生产效率.With the construction of digital Ansai Oilfield, the indicator diagrams and the polished rod loads of oil production wells have been realized real-time monitoring and data acquisition. While applying the digital indicator diagrams and load curves of oil wells, it has been fouml that the variations of polished rod loads of oil wells have some corresponding relationship with dynamic liquid level change. In this paper, the variations of polished rod loads in oil wells were used to calculate dynamic liquid levels in oil wells, and then to make the software for monitoring dynamic liquid levels in oil wells. Moreover, aeeordiug to the real-time acquisition of oil well bore conditions, it can effectively judge whether the oil well bores are at normal production status, so as to timely find out the abnormal oil wells anti assure normal production of oil fields. The application of this technology provides a theory basis lot utilizing the digitized fluid level monitoring system in oil wells to replace artificial testing in the future. This technology can effectiveiy reduce labor, realize intellectualization of acquiring basic data of oil wells, and improve the efficiency of oi]field production.
