[Abstract]:With the wide application of submersible electric pump in oil field, it is more and more urgent to monitor the performance and analyze the working condition of submersible electric pump well. In this paper, a remote monitoring system of electric submersible pump well performance based on GPRS is designed, aiming at the characteristics of scattered well position, complicated downhole operation and difficult to measure directly the parameters of electric submersible pump. In view of the deficiency of current analysis method of submersible electric pump well, the performance and working condition of electric submersible pump well are analyzed indirectly by current analysis method. The main work accomplished in this paper is as follows: 1. A hardware system for remote performance monitoring of electric submersible pump wells based on GPRS is designed, and the software of the system is programmed by mixed programming of VB and MATLAB. Long-term running tests have been carried out on motor test platform and submersible electric pump test well, and a large number of experimental data have been obtained. 3. The basic principle of current analysis based on slot harmonic method, orthogonal average linear frequency modulation Z transform (OACZT) and elimination method is introduced. A number of data acquisition tests have been carried out on many submersible electric pump wells in the oil field, and a large number of production well data have been obtained. The working conditions of production wells have been analyzed by using current analysis method, and long-term monitoring has been carried out on 1 # and 2 # submersible electric pump wells. The continuous analysis of its performance and working conditions is carried out. The results show that the current analysis method has the advantage in analyzing the working conditions of submersible electric pump wells. 4. The dynamic simulation analysis of the slotted harmonic wave method is carried out. The results show that, to a certain extent, the results of rotational speed will be affected by the fluctuation of the power grid. The remote monitoring system of electric submersible pump well performance based on GPRS designed in this paper realizes the remote monitoring of oil well performance. The current analysis method is a simple and effective method to judge the working conditions of oil wells, which provides solutions and ideas for working conditions analysis and fault diagnosis of submersible electric pumps.
