    Abstract
  • In underbalanced well completion with gel valve, gel breaking has always been performed with drill bit or by injecting gel breaker through the drill pipe. In this gel breaking operation, a delayed gel breaker is not available right now. If gel breaking can be performed automatically after well completion, time spent in tripping the drill pipe can be saved. To realize automatic gel breaking, a delayed gel breaker has been developed through sol-gel method, with tetraethyl orthosilicate (TEOS) as the precursor, SiO2 as the shell and ammonium persulfate as the core. Study on the effects of concentrations of TEOS, water and acetone, reaction temperature and pH on the coat effect showed that delayed gel breaker that satisfies the need of delaying gel breaking for 5 days at 120 ℃ can be obtained in the following conditions: molar ratio of TEOS, water, acetone and ammonium persulfate of 3：30：10：1, temperature of 40 ℃, pH of 6 and reaction time of 12 h. Characterization of the delayed gel breaker obtained with SEM has proved the existence of the coating SiO2.
