采用非常规工艺技术,提高油砂开发效益

Improve the development benefit of the tar sands with nconventional technology

文中介绍了国内外主要油砂资源的分布简况以及常用的开发方法和油砂开发带来的技术挑战,提出了多种非常规的钻井方法和工艺技术,以减少SAGD钻井过程中的材料消耗、废物排放和总体工作量,使复杂的钻井过程更简便、更快速,更可靠,从而降低油砂开发对环境的破坏,节省开发成本。

In this paper authors introduced the brief distribution of major oil sands resources in domestic and abroad and technical challenges brought by common method and the oil sands development. A variety of unconventional drilling methods and technology was put forward in order to reduce the material consumption, waste emissions in the drilling process of SAGD and the overall work. It was made the complex drilling process easier, faster, more reliable, thus reduce the development of the tar sands to the destruction of the environment, save development costs.
