植物胶冲洗液的性能及新型植物胶QM的开发研究

Studies on the Properties and Development of Natural-Vegetable-Gum Drilling Fluids

摘要:

植物胶作为钻探冲洗液已有多年的历史，主要在第四系覆盖层、松散地层、砂卵石层勘探取心有独特的效果。近年来，随着环境保护意识的加强，野生植物资源的开发受到了极大的限制，急需寻求新的可持续利用的植物胶。从常用植物胶化学组分以及冲洗液的粘度特性入手，研究植物胶的特性和改性效果，并对某种新型植物胶QM的开发与应用前景做了初步探讨。

Abstract:

Natural-Vegetable-Gum (NVG) drilling fluids have been long used. But the application of NVG has largely been restricted in the recent years because of environmental and vegetable protections. Therefore, it is urgently necessary to find further natural vegetables suitable for drilling purposes. This paper it firstly analyzes the chemical compositions and then rheological properties of regularly used NVG drilling fluids. The application prospect of a new NVG-QM is also discussed at the end of this paper.
