flow bottom hole pressure 中文意思是什麼
flow bottom hole pressure
解釋
井底流動壓力-
In consideration of the characteristics of big pressure changes in near wellbore area of low permeability reservoirs, based on experimental result, a single well percolation mathematical model that the reservoir physical property changed with effective stress was established, equations were given for calculating the elastics and elastoplastic reservoirs under the condition of oil and water flow and an analytical equation was also given for calculating the reservoir production and bottom - hole flowing pressure
摘要針對低滲油藏近井地帶壓力變化幅度大的特點,以試驗結果為基礎,建立了考慮儲居物性隨地層有效應力變化的單井滲流數學模型,給出了油水兩相流動下的彈性和彈塑性儲層的數值解計算公式,以及彈性儲層的產量和井底流壓解析表達式。 -
The results indicate that the flow velocity is lower and the pressure is high in majority of the step cylinder, the distinct variations of the flow field occur in the threshold of the step cylinder at the bottom and the abrupt transition sections, the holes in the inner and outer tubes and the exhaust hole
結果表明:步進缸內大部分區域流體流速較小,壓力較高,且變化不大,發生明顯變化的部位主要分佈在步進缸底部水管入口及截面突變處、內外套對孔處和排氣孔處。
