Remarkable effects have been gained since grease static pressure system was adopted after analyzing and comparing the journal pillows between the two CNC roll grinders.
对两台磨床的工作辊辊颈托瓦的使用情况进行比较分析,对托瓦支承采用干油静压系统,并取得显著的效果。
Oil well static pressure is relevant to reservoir depth,producing fluid level,fluid density,water cut,producing fluid index and other factors.
油井静压与油层中深、动液面、流体密度、含水、采液指数等因素有关 ,运用混液密度与含水、原油密度关系式 ,流压与混液密度、油层中深、动液面关系式计算出流压。
