Abstract

With the commercial extraction of hydrocarbons in shale and tight reservoirs, efficient methods are needed to accelerate developing process. Supercritical CO₂ (SC-CO₂) jet has been considered as a potential way due to its unique fluid properties. In this article, a new setup is designed for laboratory experiment to research the SC-CO₂ jet's characteristics in different jet temperatures, pressures, standoff distances, ambient pressures, etc. The setup is composed of five modules, including SC-CO₂ generation system, pure SC-CO₂ jet system, abrasive SC-CO₂ jet system, CO₂ recovery system, and data acquisition system. Now, a series of rock perforating (or case cutting) experiments have been successfully conducted using the setup about pure and abrasive SC-CO₂ jet, and the results have proven the great perforating efficiency of SC-CO₂ jet and the applications of this setup.
