【摘要】：潛油直線電機作為一種新型的采油技術，目前還處于研發(fā)階段，以大慶為例，，先導井試用中出現(xiàn)了有待進一步完善的現(xiàn)象，存在一定的不適應性。分析功圖是判斷抽油機井工況的基本方法。目前生產中所投入使用的示功儀為地面示功儀，而潛油直線電機舉升工藝是一種無桿舉升工藝，現(xiàn)有地面示功儀無法滿足其測試要求。因此，本文針對潛油直線電機舉升工藝開發(fā)了一套井下泵功圖的直接測試系統(tǒng)，可獲取泵況的一手資料，為進一步研究潛油直線電機的工作狀態(tài)提供重要的數(shù)據(jù)支持。 本文首先分析了潛油直線電機抽油工藝原理，建立了直線電機抽油機懸點動力分析數(shù)學模型，提出了直線電機抽油機的懸點載荷大小的計算方法。確定該舉升工藝動態(tài)參數(shù)測試的工程難點后，提出采集系統(tǒng)總體設計方案。示功儀采用存儲短接方式設計其鋼體，采用載荷傳感器直接測量運動負荷，采用加速度傳感器通過二次積分間接測量運動位移，從而構成完整功圖，核心處理器為32位STM32F103RE。上位機軟件采用C#語言開發(fā)，集成了數(shù)據(jù)提取、數(shù)據(jù)處理、圖形化顯示以及保存功能。所開發(fā)的示功儀系統(tǒng)投入使用后，有效獲取了潛油直線電機舉升工藝的井下泵功圖。通過分析可知，原有工藝泵啟動瞬間負荷過大，導致運行不平穩(wěn)等現(xiàn)象。對驅動系統(tǒng)的啟動進行優(yōu)化設計，提供了系統(tǒng)運行的平穩(wěn)性，并可定量的減小整機功率，間接提高效率。
[Abstract]:As a new type of oil recovery technology, the submersible linear motor is still in the research and development stage. Taking Daqing as an example, there is a phenomenon to be further improved in the pilot well trial, and there is some inadaptability. Power diagram analysis is the basic method to judge the working condition of pumping well. At present, the dynamometer used in production is a ground dynamometer, but the lifting process of submersible linear motor is a kind of rodless lifting process, and the existing ground dynamometer can not meet its test requirements. Therefore, this paper develops a direct testing system of pump power diagram for the lifting process of submersible linear motor, which can obtain the primary data of pump condition and provide important data support for further study on the working state of submersible linear motor. In this paper, firstly, the principle of submersible linear motor pumping technology is analyzed, the mathematical model of suspension point dynamic analysis of linear motor pumping unit is established, and the calculation method of suspension point load of linear motor pumping unit is put forward. After determining the engineering difficulty of the dynamic parameter test of the lifting process, the overall design scheme of the collection system is put forward. The dynamometer designed its steel body by means of short storage connection, used load sensor to measure moving load directly, and used acceleration sensor to measure motion displacement indirectly through quadratic integration, thus forming complete work diagram. The core processor was 32 bit STM32F103RE. The upper computer software is developed with C # language, which integrates the functions of data extraction, data processing, graphical display and storage. After the developed indicator system is put into use, the underground pump power diagram of the submersible linear motor lifting process is obtained effectively. Through analysis, the original process pump start-up load is too large, resulting in unsteady operation and other phenomena. The optimal design of the drive system provides the stability of the system operation, and can reduce the power of the whole machine quantitatively and indirectly improve the efficiency.
