Power umbrella device for testing horizontal water injection well

The invention provides a power umbrella device for testing a horizontal water injection well. The power umbrella device comprises a testing sleeve, a cable channel, an elastic deforming part and a driving assembly. The elastic deforming part is arranged at the upper end of the testing sleeve in a sleeving manner, the cable channel successively penetrates the elastic deforming part and the testingsleeve and stretches out of the testing sleeve, and the lower end of the testing sleeve is connected to a testing instrument; the driving assembly is located in the testing sleeve, is connected to theelastic deforming part and is used for driving the elastic deforming part to move axially along the testing sleeve, so that the elastic deforming part extruded by the driving assembly expands, and therefore, the cross section area of the elastic deforming part is increased. According to the power umbrella device for testing the horizontal water injection well, the elastic deforming part extrudedby the driving assembly exp
