摘　　要：河南油田为解决调整井固井质量问题，与总公司工程技术研究院共同研制出J─2B防窜降失水剂，经现场7口井试验，施工顺利，固井质量合格率100％，优质率42．9％，取得了良好的经济效益。实践证明：J─2B防窜降失水剂一方面降低了水泥浆的失水，满足了对水泥浆低失水的要求；另一方面使水泥浆具有防窜性，减轻了地层流体对水泥环的侵蚀。J－2B channeling－preventing filtration control agent was innovated by the joint efforts of Henan Oilfield and Engineering Technology Research Institute of CNPC. The rig-site applications of 7 wells shown that up to standard cementing quality rate was 100%, super cementing quality rate was 42. 9 %. A good beneficence was achieved. It can reduce cement slurry filtration, provide a channeling－preventing effect and mitigate corrosion of formation fluids on cement ring.
