Abstract
The utility model relates to onshore underground petroleum recovery equipment, in particular to a tandem type water conservancy cyclone oil water separator capable of realizing instability prevention and fine separation. At present, most of the common underground oil water separators in various large oil fields in China are formed by connecting multi-stage swirlers in series, as a result, on one hand, long and thin axial structures of the oil water separators are formed due to the multi-stage series connection of the swirlers, and accordingly, large underground space is occupied and the stability is relatively poor; on the other hand, the separation effect is not good as the diameter of a cylindrical section of a secondary swirler selected by a traditional method is equal to that of a primary swirler selected by the traditional method. The oil water separator provided by the utility model overcomes the defects that the axial length of the traditional swirlers are relatively long, the possibility of instability is high, and the secondary separating efficiency is lower, and has the following advantages: the axial length of the overall traditional cyclone separator is reduced to a half, the underground space is reduced, the stability, reliability and safety of the system are greatly improved; parallel swirler groups with small flux are adopted at the second stage, so that the separating efficiency of the secondary swirler group is greatly improved.
