The invention relates to a crown shaped gas anchor for realizing downhole gas-liquid separation, which relates to an air anchor for realizing downhole gas-liquid separation. The utility model solves the problem that the existing oil field separator can not effectively realize gas-liquid separation in the downhole. Separator joint set in the center pipe, a separator is arranged between the adjacent joint separator, settlement cup set on the central tube, two sedimentation cup inserted together adjacent, embedded multi prismatic sedimentation cup across the bowl, cup is a crown shaped settlement, settlement cup bottom of the cup for polygonal shape, angle formed between the settlement cup bottom of the cup convex edge and a horizontal line on the upper edge of the cup body sedimentation cup for cup bottom and zigzag shape corresponding to the settlement cup seat and the center pipe is arranged between the annular space of the annular space corresponding to the center tube is provided with a liquid inlet hole, multi prismatic shape insulation bowl the bottom of the cup and settlement cup, multi prismatic bowl with liquid channel isolation. The utility model is used for downhole gas-liquid separation.
