Technicans are trying to find out a more reasonable point to describe work state of pump for some reasonless factors of this model , the key technology of developing ads is on adopting a means by using theoretical calculation and curve fitting to build a reasonable pump state graph model , the model " s rationality based relations between pump efficacy and sinking depth is illustrated by restrict programme argumenting 抽油增效輔助決策系統(tǒng)的開發(fā),其關(guān)鍵技術(shù)在于采用理論計(jì)算及曲線擬合的辦法,建立合理的泵況圖模型,通過嚴(yán)格的方案論證闡明基于泵效-沉沒度關(guān)系的泵況圖模型的合理性。通過實(shí)際數(shù)據(jù),檢驗(yàn)?zāi)P偷挠行浴?
