The invention provides a sand prevention screen tube hydraulic test apparatus. The apparatus is used for testing the outer pressure resistance of a sand prevention screen tube, and the sand prevention screen tube hydraulic test apparatus comprises: a test cylinder having a closed cavity for accommodating the sand prevention screen tube; a bearing assembly comprising an elastic sealing sleeve surrounding the side direction of the sand prevention screen tube, and screen tube plugs sealing two ends of the sand prevention screen tube; and a strain test assembly comprising a strain sensor arranged on the inner side surface of the sand prevention screen tube. The sand prevention screen tube hydraulic test apparatus allows the uniform radial force to be applied to the whole sand prevention screen tube and a test method to be highly scientific; and a hydraulic value obtained in the invention is the practical outer pressure resistance of the screen tube, and does not need conversion. The sand prevention screen tube hy
