| 中文摘要:常规水泥封孔材料不能完全满足涌水含气特殊地层条件的封孔要求。以封孔水泥砂浆为研究对象,通过正交实验方法,设计封孔水泥砂浆的成分配比,得到既满足钻探质量指标要求,又适用于涌水含气地层的封孔材料配方。由室内实验得到,水灰比的改变对湿态水泥砂浆的凝结时间具有显著影响。结合通地1井,根据不同的井段要求,应用相适应配方的封孔材料进行野外应用实验。结果表明,设计的封孔材料能够满足涌水含气地层的封孔质量要求。 |

| Abstract:The conventional plain cement sealing material cannot fully meet the sealing requirements of the special geological formation with water gushing and gas bearing. Taking the sealing cement mortar as the research object, the proportion of cement mortar was designed by orthogonal experiment, the formula of the sealing material suitable for the water gushing and gas-bearing formation was obtained, and the technical requirements for borehole sealing quality are obtained. On the basis of laboratory experiments and combined with the specific formation conditions of Tongdi well1, the field application tests were carried out with the corresponding sealing material formula according to the sealing quality requirements of different well sections. The results show that the designed sealing material formula can meet the requirements of borehole sealing quality in the water gushing and gas-bearing formation. |
