Experimental Study of New Sealing Material for Hydraulic Fracturing Drilling
Abstract：According to the status that the current sealing materials can not meet the requirement of high-pressure sealing for hydraulic fracturing drilling,it developed the high pressure sealing material that is suitable for hydraulic fracturing technology.Through the contrast with performances of expansion cement and polyurethane,this modified resin solves the problem that expansion cement can not seal the level hydraulic fracturing drilling depends on expanding equably.In addition,the compressive strength of the modified resin is higher than polyurethane significantly,so it could meet the requirement of resisting high-pressure.
