| 摘 要： | 在分析现有堵水技术存在问题的基础上,提出了既能堵水又能疏油的新思路。通过室内实验获得了具有选择性渗透性能的堵水疏油的水泥浆体系配方;用试验研究了其水泥石强度、渗透率、选择性渗透性能随组分及其加量的变化规律;并分析了该水泥浆体系堵水疏油的机理。试验表明,这种水泥石抗压强度可达7.6~21.65 MPa,油相渗透率可达0.69μm2,油、水相渗透率比值可达4.28~16.48。 |

| Abstract: | Based on the analysis of problems existing in some conventional technology for water plugging, a new idea has been presented. A cement slurry system that has selective permeability,both water plugging and oleophobic property has been obtained by laboratory experiments. Meanwhile, some factors such as crushing resistance and permeability of the cement, the influence of the components and their dosage on the selective permeability have been studied. Results show that the compression strength can reach 7.6-21.65MPa after WOC, its permeability 0.69μm2, and the ratio of kerosene to distilled water permeability 4.28-16.48. |
| Keywords: | water plugging cement slurry phase permeability oleophobic |
