| 摘 要： | 对于低渗、低孔气藏,在修井作业中,对暂堵体系有较高的要求。常规堵漏材料,膨润土固相颗粒、高分子聚合物凝胶等,不能有效进入地层进行封堵,且易造成漏失污染地层,同时也存在难于返排或者返排率低的问题。因此,研究一种适合低渗气藏的暂堵液显得尤为重要和紧迫。本文结合靖边气田地质特征及气井特点,对微凝胶颗粒新型堵剂进行室内评价,分析颗粒与低渗储层孔隙配伍性、暂堵能力、抗温抗盐能力等,探讨新型暂堵剂对于低渗、低孔气藏的适应性。 |
| 关 键 词： | 低渗透 暂堵 抗温抗盐 微粒运移 |

| Abstract: | Repair of gas well operations have some high demand for low permeability, low porosity gas reservoir. Conventional sealing materials can not meet the requirements, on the contrary will cause pollution, and the same time there is also the problem difficult to return or low of flow back rate. Therefore, a suitable polymer gel particles for low permeability gas reservoir is particularly important and urgent.On the basis of the geological characteristics of the gas field, evaluate the new type of gel particles, analyze compatibility of the particles and the low permeability reservoir pore, temporary blocking capability, Anti-temperature and salt tolerance. Explore the adaptability of new type Polymer gel particles for low permeability gas reservoir. |
| Keywords: | low permeability temporary blocking temperature and salt resistance particlemigration |
