发明名称 Down-hole gas anchor device
摘要 The present invention is used to separate gas from liquid while being placed downhole in a hydrocarbon producing well. It essentially comprises a means to divert hydrocarbon production fluid from within a tubing string into the annulus of the well. This diversion turbulently mixes the fluid and releases free gas from the liquid. Thereafter, the liquid migrates downward while the free gas migrates upward to a gas collection apparatus. The liquid is reuptaken at an intake spot below the point at which it was diverted. It travels upward through a concentric chamber and subsequently reenters the tubing string at a point above that which it was diverted.
