用于从携带固体的钻井流体分离固体的设备和方法
Abstract:
种用于将固体从携带固体的钻井流体分离并且选择性地将所述固体进行筛分的设备和方法,所述设备包括篮(312),振动机构(314),第筛板(318b)及安装在所述第筛板下方的第二筛板(318c),和导向装置,其用于选择并联操作模式或串联操作模式,在并联操作模式中,携带固体的钻井流体流在所述第筛板和所述第二筛板之间分开,在串联操作模式中,携带钻井流体的固体导向到所述第筛板,然后由第筛板筛过的钻井流体被导向到所述第二筛板上,其中,所述设备还包括可动分流器盘,用于选择并联操作模式或串联操作模式,其中,所述可动分流器盘(320)能滑动地布置在导轨(320a)中,所述导轨包括可膨胀元件(320p,320s),用于选择地将所述可动分流器盘(320)固定在所述导轨(320a)中。
Abstract(English):

An apparatus and method for separating solids from solids laden drilling fluid and selectively sizing the solids, the apparatus comprising a basket (312), a vibratory mechanism (314), a first screen deck (318b) and a second screen deck (318c) mounted below said first screen deck and a directing device for selecting a parallel or series mode of operation in which flow of solids laden drilling fluid is divided between the first deck and the second deck and a series mode of operation in which solids laden drilling fluid is directed on to the first screen deck and then drilling fluid screened thereby is directed on to said second screen deck, wherein the apparatus further comprises a moveable diverter tray for selecting parallel or series mode of operation, wherein said moveable diverter tray (320) is slideably arranged in rails (320a) having an expandable element (320p,320s) to selectively fix said moveable diverter tray (320) in said rails (320a).
