由于輸油泵機組容量偏大,其流量和儲油罐液位控制均采用人為節(jié)流調節(jié)控制等因素,造成了該生產工藝系統運行效率不高、設備易損件故障頻繁和“大馬拉小車”等現象的發(fā)生,這不僅嚴重浪費了能源,而且影響油井的正常生產和原油產量的完成。為此我們于2005年初提出了在30kW的CSY11-2油氣混輸單螺桿泵上推廣應用了森蘭SB70G變頻器進行調速控制,安裝了質量可靠的變頻調速設備,以解決生產中的諸多實際問題,見到了良好的現場使用效果,取得了顯著的經濟效益和社會效益。 二、控制方案 新灘油田162油氣混輸站和191油氣混輸站油氣混輸泵機組的變頻調速技術控制方案采用了閉環(huán)控制或開環(huán)控制方式,閉環(huán)控制與開環(huán)控制方式分別如圖1﹑圖2所示,以滿足現場生產工作的需要。
2.1現場生產工藝流程 162站管理著7口油井,油井來油先進入2.7米高的40方儲油罐,經加熱后由30kW的CSY11-2油氣混輸單螺桿泵將油井產出物輸送至幾十公里外的油氣接轉站。191站生產工藝流程與162站基本相同,目前管理著5口油井,油氣輸送距離比162站更遠。 2.2閉環(huán)控制應用技術方案 在40方儲油罐上安裝帶4~20mA模擬信號輸出的浮球液位計,將液位信號給變頻器,變頻器在接收液位計信號后與變頻器設定值比較,采用PID調節(jié)控制算法,通過變頻器輸出頻率的變化來自動調節(jié)和控制儲油罐的液位高度,達到節(jié)能降耗和油井生產平穩(wěn)運行自動控制的目的。儲油罐的液位控制高度為1.6米。
