摘　　要：针对中低渗透油藏存在高渗透条带或微裂缝，在堵调治理过程中易发生堵调剂漏失的问题，以聚硅成胶液和交联稳定液为原料，研制开发出XNJG堵漏剂。其易在地层中滞流，耐温80-160℃、耐盐3000—50000mg／L。该堵漏剂热稳定性好、耐冲刷、对非均质严重的岩心具有很强的调剖改流能力。将该堵漏剂在孤岛油田进行3口井4井次调剖试验，获得较好效果。A plugging agent XNJG was prepared with polysilicone gelling solution and crosslinking stabilizing solution as materials for resolving the problems of profile modification agent losing during plugging and modifying high permeable zone or tiny crack in middle and low permeable reservoir. XNJG settled easily in stratum and resisted temperature 80 - 160℃ and salinity 3 000 - 5 0000 mg/L. It showed the performances of good hot resistance,good outwash resistance and strong profile modification to anisotropic cores. The results of the application tests in Gudao Oilfield were satisfying.
