Title:
DYNAMIC FRACTURE PLUGGING EVALUATION EXPERIMENT APPARATUS AND EXPERIMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/099785
Kind Code:
A1
Abstract:
A dynamic fracture plugging evaluation experiment apparatus and an experiment method therefor. The dynamic fracture plugging evaluation experiment apparatus comprises a fracture simulation experiment instrument (1), a liquid storage container (3), a recovery tank (4), a hydraulic pump (5), a hand pump (6), a liquid weighing electronic scale (7), an inlet pressure gauge (8), an outlet pressure gauge (9), a first back pressure valve (10) and a second back pressure valve (400), the fracture simulation experiment instrument (1) being provided with a dynamic fracture simulation mechanism. The dynamic fracture plugging evaluation experiment apparatus can simulate a dynamic change process of the fractures from closing to opening, realize the simulation of the plugging process of the dynamic fractures, and monitor in real time and evaluate the plugging effect and plugging position in the dynamic fractures.
