SAND CONTROL USES PHENOLIC RESIN AND SAND CONSOLIDATION USES MODIFIED RESIN

This paper has discussed characteristics of phenolic resin covered sand and modified resin sand consolidation agent in details. Phenolic resin covered sand is through physical method to make the surface of quartz sand overlapped by phenolic resin, when the temperature get to a fixed temperature, the resin at the surface of covered sand began to softened and consolidated.The compression strength and permeability of the consolidated resin covered sand will be influenced by concentration of resin, diameter of quartz sand and consolidating temperature and so on.The test show when the concentration of resin is 12% and temperature is above 60℃, both the compression strength and permeability of resin covered sand are high.The resin covered sand is adaptable for some voidage formation, it has been used in 50 wells in Jidong Oilfield on site, the effect is good.the modified resin sand consolidation agent for sand control is double flow sand control, tests indoors and on site show modified resin sand consolidated agent can be fit for wider temperature scope and consolidated strength is higher, which can be used in primary period of sand control.
