    • A novel inlet and baffle structure for a drilling and degasser is provided. Gas-cut mud is fed into the degasser vacuum chamber through a horizontal inlet pipe having a long slot cut in its bottom wall. The mud flow is formed into a thin curtain as it passes through this slot. At the same time, its rate of movement is accelerated, with a consequent increase in shear and drop in viscosity. The mud immediately contacts a generally horizontal baffle. The flow is divided into two turbulent, thin layers. It is then conducted through a system of baffles. Due to the change in mud viscosity, induced turbulence and the forming of the mud flow into thin layers of large area, the vacuum within the chamber is able to effectively separate the entrained gas from the mud.
    • 提供了一种用于钻孔和脱气机的新型入口和挡板结构。 气体切割泥浆通过其底壁中具有长槽切割的水平入口管进入脱气器真空室。 泥浆流通过这个槽时形成一个薄的窗帘。 同时,其运动速度加快,随之而来的剪切和粘度下降。 泥浆立即接触一个大致水平的挡板。 流动分为两层湍流薄层。 然后通过挡板系统进行。 由于泥浆粘度的变化,引起的湍流和泥浆流形成大面积的薄层,室内的真空能够有效地将夹带的气体与泥浆分离。
