为此,采用自行研制开发的JHT-02高温高压固井质量评价仪(物理模型按10∶1缩小,并制作了相应的缩小换能器),模拟高压深层井段不同孔隙度与渗透率的砂岩与泥岩,进行了水泥与不同岩性地层胶结性能的试验,对比试验结果及现场测井曲线,发现:对于深井中存在异常高压的井段,地层岩性和孔渗性能影响水泥与地层的胶结强度,随着孔渗性能的变化,水泥与泥岩和砂岩地层的胶结强度变化规律一致,随孔隙度与渗透率的增加胶结强度下降;在高压常温环境下,水泥与砂岩地层的胶结强度要低于水泥与泥岩地层的胶结强度;对于相同渗透率的泥岩地层,高压带较低压带胶结更理想;建议在高压常温井段选择合适的钻井液体系,防止水泥浆在高渗地带过多失水,以提高固井质量。
