A ccording to the poor cond ition o f the h igh o i-l gas ratio
in o il w e lls, a set o f o i-l g as separating lab instrum ents are
built and tw o types o f sepa rato rs􀀁 separating e ffects are
tested. A new h igh effic ient separator is des igned after
analyzing the inner struc ture o f the separator. Design ing
double class structu re, add ing one c lass separa tion round,
adopting im pe ller and the structure o f h igh pressure resisted
round, a ll of these aspec ts result in a h igh separating effect.
The application of the o il w e ll env ironm ent a t the h igh gasliqu
id ratio m akes the ratio increase from the o rig ina l GLR
0. 3 cubicm e ter per ton to GLR 0. 6 cubicm eter per ton. The
w ho le separa tion effec t under the env ironment o f GLR 0. 6 is
im proved from the or ig ina l 75% to 95%. The result is very
good after compar ing the e ffects.
