Abstract

See full text

The present invention discloses a shale stress sensitivity testing device and method. The testing device comprises a support table. The left and right ends of the upper surface of the support table are respectively provided with a left side plate and a right side plate. The top of the left and right side plates are connected with the left and right ends of the top plate. The chucks of the clamps are capable of reciprocating motion in the horizontal direction and circular motion in the front-rear direction. The present invention can change the intensity and direction of the effective stress of the rock sample, and determine the permeability of the rock sample under different effective stresses, thus enabling comprehensive testing of the stress sensitivity of shale in different directions and enhancing the accuracy of shale stress sensitivity testing.
