【摘要】：隨著潛油電泵在油田的廣泛應用,對潛油電泵井進行性能監(jiān)測和工況分析的需求越來越迫切。本文針對潛油電泵井位置分散、井下運行狀況復雜、電泵參數(shù)不易直接測量的特點,設計了基于GPRS的潛油電泵井性能遠程監(jiān)測系統(tǒng);鑒于目前潛油電泵井工況分析方法的不足之處,采用了電流分析法間接分析潛油電泵井的性能和工況。本文完成的主要工作有:1.設計了一套基于GPRS的潛油電泵井性能遠程監(jiān)測硬件系統(tǒng);以VB和MATLAB混合編程方式編寫了系統(tǒng)軟件。2.在電機測試平臺和潛油電泵實驗井上進行了長期的運行測試,獲得了大量的實驗數(shù)據(jù)。3.介紹了基于齒槽諧波法、正交平均線性調(diào)頻Z變換(OACZT)和消去法的電流分析法的基本原理;在油田現(xiàn)場的多口潛油電泵井上進行了多次數(shù)據(jù)采集試驗,獲得了大量生產(chǎn)井數(shù)據(jù),采用電流分析法對生產(chǎn)井的工況進行了分析,并對1#和2#潛油電泵井進行了長期監(jiān)測,對其性能和工況進行了連續(xù)分析。結(jié)果表明:電流分析法在分析潛油電泵井工況方面具有優(yōu)勢。4.對齒槽諧波法進行了動態(tài)仿真分析。結(jié)果表明:轉(zhuǎn)速結(jié)果在一定程度上會受電網(wǎng)波動影響。本文設計的基于GPRS的潛油電泵井性能遠程監(jiān)測系統(tǒng)實現(xiàn)了油井性能的遠程監(jiān)測;電流分析法簡單有效的判斷了油井的工況,為潛油電泵井工況分析和故障診斷提供了解決方案和思路。
[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.
