摘要
就调整井固井的技术难点、影响因素、水窜的根源和防窜材料的作用机理进行了讨论、分析 ,对中国各油田采取的防窜工艺措施和现用抗水窜水泥浆体系的固井效果和存在问题进行了分析和评价。
In resent years,the water channeling is a serious problem during cementing of adjustment well in China which affects cementing quality and oil-gas recovery.The paper discusses the technical difficulty of cementing of adjustment well,influence factors,causes of water channeling and anti-channeling material.The anti-channeling technology,and cementing result of the cement slurry system used for anti-channeling are analysed and evaluated.Finally,the properties of the anti-channeling additives and technical demands of cement slurry system used for anti-channeling are proposed.
