Abstract:

Low-density proppant is a kind of high performance proppant prepared by chemical modification, physical modification and other methods. It has the characteristics of low-density and low settling rate. In this paper, based on the research of literature, according to the different modification methods,low-density proppant could be divided into low density porous uncoated ceramic proppant, porous inorganic coated low-density proppant, porous resin coated low-density proppant. We compared the different types of low-density proppant preparation system composition, density and pressure performance and summarized the mechanism of preparing different types of low-density proppant, the main influence factors and the proppant application. According to different preparation methods, ultra-light weight proppants(ULWP) were divided into two categories: conventional preparation and new technology preparation. The author suggested combining with various additives, optimizing the firing process, exploring the crystal structure such as corundum and mullite phase to realize effective combination of low-density and high strength of proppant. Hydrophobic modification and structure modification methods could be used to develop multi-functional, high performance proppant. All these were provided as reference for related research.

Key words: proppant, preparation, low-density, high strength, ultra-light weight

摘要:

低密度支撑剂是通过化学改性、物理改性等方法制备得到的高性能支撑剂,具有密度低、沉降速度低等特性。本文在调研大量文献基础上,根据改性方法不同将低密度支撑剂分为多孔无包覆陶瓷低密度支撑剂、多孔无机物包覆低密度支撑剂、多孔树脂包覆低密度支撑剂,对比了不同类型低密度支撑剂制备体系组成、密度以及承压性能,总结了制备不同类型低密度支撑剂的机理、主要影响因素及应用情况。根据制备方式不同将超低密度支撑剂(ultra-light weight proppants, ULWP)分为常规方法制备、新技术制备两类。提出未来可通过结合使用多种添加剂、优化烧制工艺等方式探索莫来石相、刚玉相等晶体结构,实现支撑剂超低密度与高强度的有效结合,利用疏水改性、结构改性等方式向多功能、高性能发展,为相关研究提供借鉴和参考。
