| 摘 要： | 大牛地气田储层属于低压、低渗透气藏，具有钻井过程中个别井段易漏和单井产量低的特点，储层保护十分重要。通过对该气田储层物性特征的分析和敏感性评价，针对水泥浆对气层污染的机理，研究出污染程度小的水泥浆体系和固井工艺技术。大牛地气田227井次的固井施工表明，固井质量优质率迭92．7％，合格率迭100％，而且水泥浆对气层的污染深度只有5，16cm，通过射孔完全可以解除。

| Abstract: | Daniudi gas field, a low pressure and low permeability gas reservoir, has the characteristics of well circulation loss in certain section during drilling and low well productivity. Therefore the protection of the reservoir is very important. Based on the reservoir characteristic analysis and sensitivity evaluation of this gas reservoir, cement slurry with low pollution and cementing technique were obtained. The results of 277 wells cemented in Daniudi gas field indicate that 92.7% have high quality and 100% meet the specified requirement, and the most important is that the pollution depth by cement slurry is only 5.16 cm which can be removed completely by perforation. |
