修井機為油田生產油氣井的穩定、高效產出發揮著重要作用,其通過起下管柱、井內循環及旋轉等操作,完成沖砂、清蠟、檢泵、打撈、堵漏、防砂、修套及開窗等一系列作業。隨著節能減排、環保等新政策的推廣以及油田穩產增產壓力的加大,開發新型修井機的需求日益增長。
1 設計特點
新型XJ1800DBZ電動修井機在傳統柴油機配置的基礎上,集成了變頻控制及液氣電控制,可采用電機或柴油機進行修井作業,滿足最大鉤載不超過1 800kN的修井作業。新型XJ1800DBZ電動修井機設計特點如下。
①控制性好。動力系統采用變頻調速技術,使用變頻器控制變頻調速電機為絞車及轉盤提供主動力,能夠實現速度無級控制,滾筒轉速在設定范圍內連續可調,減少了頻繁換擋,可根據作業情況靈活掌握絞車轉速及大鉤載荷?!?br>
