Software Development Of Efficiecy Monitoring Evaluation And Optiization Of Rod Pumping System

Rod pumping is a very popular means of mechanical oil production. Using the computer technology to monitor and evaluate the condition of rod pumping system is important for improving the efficiency of oil production. In this paper, according to actual requirement, a set of software is developed for this purpose. The main content is in the following:First, the function of this software is determined after collecting and analyzing the requirements from oil field. Then, the methods of implementing above function are discussed, and the whole framework of the software is established.The way of collaboration between numerical simulation process and GUI (Graphics User Interface) process is designed. Based on the working principle of rod pumping system, first, the single-well simulation method for single-scheme and multi-scheme is provided, then, this method is extended for multi-well simulation.Several storage formats of measurement data are analyzed, the data reading methods for program are achieved and corresponding conversion tools are developed. Considering the basic parameters of rod pumping system, an analytical arithmetic of single-group measurement data is given. The function dealing with continuous measurement data during a fixed time range is realized and trends of the output data are obtained.For the convenience of obtaining the final report, an automatic report generation function is realized. Basic parameter database of rod pumping system is built, the access to database by means of program is accomplished. The function of database management is designed with SQL. Considering the security and stability of the software system, a mode of multi-user with different operation grades is designed. Finally, help documents for this software are developed.
