Abstract: Water shutoff work for fracture-vuggy carbonate reservoirs in Tahe Oilfield encounters some difficulties, including difficult water shutoff agent optimization, serious agent leaking, and unmatched leakage plugging treatment. To solve the problem, the paper analyzed the present status of the water shutoff technique for fracture-vuggy carbonate reservoirs, and conducted the anticipation and cause analysis on agent leaking. And it also summarized the temporary plugging and leakage plugging agents, including three kinds of temporary plugging agents, which were middle density solidified particles, expansion particles and soluble silicate gel, and two kinds of water plugging techniques, which were composite density selective plugging with bridging particle and multistep composite slugs plugging with guanidine gum liquid as preflush. Field tests proved that the temporary plugging and leakage plugging techniques showed good effect for different leakage degree wells.
