| 摘 要： | 塔河油田托普区块二叠系地层承压能力低,裂缝较发育,易破碎、垮塌,严重影响着三开中途完井固井质量。针对该区块地层特点,优选了雷特堵漏剂作为主要堵漏材料,该堵漏剂以颗粒架桥、楔入承压、封门加固相结合的方式进行堵漏,并具有片状易楔入、耐高温不易变形等特点,特别适合深井及恶性漏失井的堵漏。实验筛选了堵漏浆配方并进行评价,制定了堵漏方案及施工工艺。在塔河油田4口井的二叠系漏失地层进行了承压堵漏施工,取得了良好的效果,应用井一次堵漏成功率为100%,均达到工程设计要求的承压值,堵漏施工周期由平均9.53 d缩短至2 d以内。 |

| Abstract: | The challenge of mud loss is often encountered in Permian Tuofu block of Tahe oilfield,because the formations are fractured and caving happens frequently,which does harm to the cement quality of the third hole.Applying the Neotor sealing products as the main plugging material,it is fit for the serious mud loss in deep wells.Through the experiments,formulations of sealing mud are optimized,and the applications in 4 wells show that the first success rate is 100%,and the sealing operation period decreases from... |
