System and method for perforated well sand control

摘要

In one embodiment, a system includes a cased wellbore disposed in a formation of interest. The system includes an emulsion positioned in the wellbore at a depth of the formation of interest. The emulsion includes an oil external phase and an aqueous internal phase. The oil external phase includes particles having calcium hydroxide. The aqueous internal phase includes insoluble silica particles. The system further includes a perforating tool that generates perforation tunnels through the cased wellbore into the formation of interest. The system further includes a well flow control device that shuts in the wellbore for a specified period of time. The emulsion breaks during contact with the formation in the perforation tunnels, and the calcium hydroxide and silica particles form a cementitious material that consolidates the perforation tunnels.
