高水速凝材料用于石油工程的室内研究

LABORATORY STUDY OF AQUEOUS ACCELERATED MATERIAL IN PETROLEUM ENGINEERING

  • 摘要: 高水材料是一种能够在高水灰比 2.0~3.0情况下迅速凝固,并形成具有一定强度水泥石的无机胶凝材料。测试了普通高水材料与石油工程有关的性能。首次对高水材料在石油工程上应用的可行性进行了分析。研制了适合石油工程使用的高水材料,这种材料配制的水泥浆密度可达 1.2~1.3g/cm3,2 4h强度达 3.0MPa,稠化时间可调整到 2 0 0~4 0 0min,可用于低压和易破裂地层固井。同时还可用于MTC技术和废弃钻井液的固化,由于流动时稠化时间长,静止时迅速凝固,因此,可用于堵漏和堵水;在控制粉磨粒径的基础上还可用于防砂。

     

    Abstract: The aqueous material is a kind of inorganic gelling material that can rapidly get solidificated under high water to cement ratio of 2.0~3.0, and then forms the cement bond with certain strength. Its performances that related to the petroleum engineering are tested, and the feasibility of using this material in petroleum engineering is also investigated.A kind of petroleum used aqueous material is developed, and the cement slurry mixed with this material can be used in the cementing operations of low formation pore pressure and in fragile formations, as its density reaches 1.2~1.3g/cm3, and strength after 24h is 3MPa, thickening time can be adjusted to 200~400mins. This material can also be used in MTC technology, to convert the waste drilling fluid into cement slurry. For its feature of long thickening time in flowing and fast solidification in static, it can be used in lost circulation plugging and water plugging. Sand control by this material is also possible when the particle size is controlled.
