Review of the theory System research on flexible continuous steel sucker Rod Pumping System
Oil Field Equipment, 2002Co-Authors: Zhang Si-weiAbstract:This paper describes the main methods, conclusions and views of current research on flexible continuous steel sucker Rod Pumping System as well as main problems in current research, presents the preliminary idea and solution to establish a theory System of flexible continuous steel sucker Rod. Currently, theoretical analysis of flexible continuous steel sucker Rod Pumping System usually adopts traditional methods used in rigid steel Rod Pumping System. The dynamics model in flexible continuous steel sucker Rod Pumping System hasn't reflected its constructional and physics characteristics. It copies the Rod's vibration damping coefficient of conventional steel sucker Rod completely. It's hard to make proper analysis of actual performance of flexible continuous steel sucker Rod Pumping System only according to the result from this vibration equation, and hard to properly explain the actual dynamics diagram, its output and reasons that make Pumping efficiency increase. So it's in need to establish a working theory, which can reflect the characteristics of flexible continuous steel sucker Rod string completely, objectively and Systematically.

Optimization design of wire rope sucker Rod Pumping System
Acta Petrologica Sinica, 2005Co-Authors: Tan Chao-dongAbstract:A optimization method for design of wire rope sucker Rod Pumping System in wellbore was developed by means of System engineering nodal analysis.This design method can be used to quantitatively calculate the coordination point of inflow and outflow in wells,scientifically select Pumping parameters and taper of Rod,analyze force profile of compound Rod comprised of wire rope,sucker Rod and weight bar and also used to predict dynamic working states including output,stroke efficiency,Pumping efficiency and downhole System efficiency affected by key Pumping parameters such as Pumping depth,stroke,frequency of stroke and pump piston size.The software worked according to this method was innovated.The calculation result by the software can provide theoretical references to the optimization of Pumping parameters in wire rope sucker Rod Pumping System.The better benefits have been achieved in practice.

A Fault Diagnosis of Suck Rod Pumping System Based on SVM
Applied Mechanics and Materials, 2013Co-Authors: Yu Zhou, Hang Xin WeiAbstract:Aiming at the defects of fault diagnosis in the traditional method for sucker Rod pump System, a new method based on support vector machine (SVM) pump fault diagnosis is proposed. Through studying the theory of invariant moment and the shape characteristics of pump indicator diagram, seven invariant moments is extracted from the indicator diagram as a Pumping unit well condition of the characteristic parameters. Then these parameters are pretreatment, and it makes up seven eigenvector which are regarded as the input eigenvector of the SVM. The experiment indicates that the method can not only detect the fault of the Pumping oil well but also can recognize the fault type of it, which is very effective for safety protection and fault diagnosis of the Pumping oil.

a fault diagnosis of suck Rod Pumping System based on wavelet packet and rbf network
Advanced Materials Research, 2011Co-Authors: Wen Li Sun, Hang Xin WeiAbstract:In order to diagnose the fault of the pump oil well, a fault diagnosis method based on the wavelet packet and the neural network is intRoduced. Firstly, the dynamometer card of the Pumping well is gathered and normalized, then these data are decomposed by using three layers of wavelet packet. It makes up eight energy eigenvectors which are regarded as the input eigenvector of the RBF network. The experiment indicates that the method can not only detect the fault of the Pumping oil well but also can recognize the fault type of it. It shows that the method is very effective for safety protection and fault diagnosis in the Pumping oil well.

Selection of Pumping model for wire rope sucker Rod Pumping System
Acta Petrologica Sinica, 2004Co-Authors: Tan ChaoAbstract:The Pumping model of wire rope sucker Rod Pumping System was developed by means of predicting calculation.This model can be applied to determine the optimum Pumping parameters,taper of Rod and Pumping devices in middle or low-pRoduction deep well.The analysis results show that when applying this Pumping System in middle or low pRoduction deep well,the best Pumping model is the compound Rod comprised of longer length stroke,lower Pumping speeding,middle or small pump diameter,tubing being anchored and small diameter wire rope sucker Rod with larger-diameter weight bar.This Pumping model is suitable for enhancing the effective stroke and efficiency of Pumping System and reducing the consumption of energy.Moreover,it is pointed that application of hydraulic Pumping unit is propitious to exert fully the effective stroke of wire rope sucker Rod,while sucker pump of heavy oil with large diameter makes against the exertion of the merit of the Rod.
