【摘要】：随着潜油电泵在油田的广泛应用,对潜油电泵井进行性能监测和工况分析的需求越来越迫切。本文针对潜油电泵井位置分散、井下运行状况复杂、电泵参数不易直接测量的特点,设计了基于GPRS的潜油电泵井性能远程监测系统;鉴于目前潜油电泵井工况分析方法的不足之处,采用了电流分析法间接分析潜油电泵井的性能和工况。本文完成的主要工作有:1.设计了一套基于GPRS的潜油电泵井性能远程监测硬件系统;以VB和MATLAB混合编程方式编写了系统软件。2.在电机测试平台和潜油电泵实验井上进行了长期的运行测试,获得了大量的实验数据。3.介绍了基于齿槽谐波法、正交平均线性调频Z变换(OACZT)和消去法的电流分析法的基本原理;在油田现场的多口潜油电泵井上进行了多次数据采集试验,获得了大量生产井数据,采用电流分析法对生产井的工况进行了分析,并对1#和2#潜油电泵井进行了长期监测,对其性能和工况进行了连续分析。结果表明:电流分析法在分析潜油电泵井工况方面具有优势。4.对齿槽谐波法进行了动态仿真分析。结果表明:转速结果在一定程度上会受电网波动影响。本文设计的基于GPRS的潜油电泵井性能远程监测系统实现了油井性能的远程监测;电流分析法简单有效的判断了油井的工况,为潜油电泵井工况分析和故障诊断提供了解决方案和思路。
[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.
