有杆抽油系统诊断方法研究与应用

以有杆抽油系统动力学行为分析为基础，将基础理论研究和应用技术有机地结合起来，建立了考虑悬挂系统弹性的直井和定向井有杆抽油系统诊断模型，研究了基于B/S（Brower/Server）模式的有杆抽油系统故障诊断方法，利用Internet技术和Web技术开发了相应的软件系统, 通过浏览器即可实现对有杆抽油系统快速、准确的故障诊断，并给出了诊断算例，诊断结果验证了该系统的有效性。基于B/S模式的有杆抽油系统故障诊断对避免井下作业的盲目性，提高系统效率，降低采油成本，实现油田企业信息化和提高油井的科学管理水平具有重要意义。

Study of the Method to Diagnose Suker Rod Pumping System and It's Application

Based on the analysis of dynamics behavior of sucker rod pumping system,the model for fault diagnosis of sucker rod pumping system in directional and straight wells in consideration of flexibility of hanging system is established.A method to diagnose the fault of sucker rod pumping system based on B/S Mode is studied.Fault diagnosis system of sucker rod pumps which is based on B/S mode software by using Internet and Web technology is developed.The diagnosis system can diagnose fault of sucker rod pumping system by browsing swiftly and accurately.And then the paper gives an calculation example,the result proves the validity of this system.The fault diagnosis based on B/S mode has great significance for preventing blindness of underground operation,improving the system efficiency,reducing the oil production cost and raising scientific management level of oil well.Meanwhile,it improves enterprise′s information based degree of oil field,lays the foundations of realizing Digital Oil Field.
