Description

technical field [0001] The invention relates to a device and method for measuring the tensile properties of high elastic materials, in particular to a device and method for quickly measuring the tensile properties of high elastic materials, belonging to the technical field of petroleum exploitation. Background technique [0002] In recent years, the experimental and theoretical research on flexible plugging agents has become a hot spot. This plugging agent is mainly aimed at the problems of bulky granular plugging agents, such as fast water absorption, poor deformation, low strength after expansion, easy to break, and unfavorable for deep profile control. And developed a highly elastic granular material. [0003] It is generally believed that such highly elastic particles have super strong deformation ability, and can be arbitrarily squeezed and stretched to produce deformation. This performance ensures that the highly elastic particles can produce temporary plugging, defor...
