堵剂优选困难、堵剂漏失严重、堵漏措施难以配套，是塔河油田碳酸盐岩缝洞型油藏堵水亟待解决的难题。为解决这些难题，针对碳酸盐岩缝洞型油藏的堵水现状，开展了堵剂漏失的预判和原因分析，分析研究了适合塔河油田特色的暂堵和堵漏工艺，主要包括中密度固化颗粒、颗粒型体膨堵剂、可溶性硅酸盐凝胶3项暂堵工艺；复合密度选择性堵水、瓜胶液前置多级复合段塞堵水2项堵漏工艺。经现场应用表明，针对不同漏失程度的井，3项暂堵和2项堵漏工艺应用效果较好。

Water shutoff work for fracture-vuggy carbonate reservoirs in Tahe Oilifeld encounters some dififculties, including dif-ifcult 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 solidiifed 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 prelfush. Field tests proved that the temporary plugging and leakage plugging techniques showed good effect for different leakage degree wells.
