Heavy oil reservoirs are widely scattered across China with proved reserves over 10 billion tons, most of which are unconsolidated sandstone reservoirs. As a consequence, some problems are encountered as to the choice of production stimulation and stabilization process. This paper attempts to provide a summary of the geological characteristics of heavy oil unconsolidated sandstone reservoirs and the difficulties of production stimulation reconstruction process, in order to preferably choose the system for cleaning, viscosity reducing, acidizing and unplugging, optimize the construction process of viscosity reducing and acidizing, guarantee that service fluids can enter reservoirs uniformly, and improve the deliverable of chemical production stimulation, which would be taken as a good reference for chemical production stimulation construction of heavy oil unconsolidated sandstone reservoirs.
