Method for construction of anti-filtration screen round vertical stem includes drilling from surface of technological and plugging wells with following pumping in through those of plugging solution. To decrease cost and labor consumption of construction of anti-filtration screen from technological well one penetrates curvilinear well in direction to center of the stem, from that one drills to depth of stem screw or straight plugging well. Type of well is determined from ratio between permitted radius of curvature of well and conditions of strength of screen against effect of hydrostatic pressure of water-bearing horizon.
