摘要： Wellbore plungers with non-metallic tubing-contacting surfaces and wells including the wellbore plungers. The wellbore plungers are configured to be utilized within a tubing conduit of the downhole tubing. The downhole tubing includes a non-metallic tubing material that defines a non-metallic tubing surface. The non-metallic tubing surface at least partially defines the tubing conduit. The wellbore plungers include an uphole region, which defines an uphole bumper-contacting surface, a downhole region, which defines a downhole bumper-contacting surface, and a plunger body. The plunger body extends between the uphole region and the downhole region and defines a downhole tubing-contacting surface. The downhole tubing-contacting surface is configured for sliding contact with the non-metallic tubing surface, defines a sealing structure configured to form an at least partial fluid seal with the downhole tubing, and is at least partially defined by a non-metallic tubing-contacting material.
