压裂支撑剂新进展与发展方向

压裂支撑剂是油气储层改造中用来支撑压裂人工裂缝的一种关键材料，是提高压裂成功率和大幅提高改造效果的关键。国外近年来研发了一系列新型支撑剂，值得我们学习借鉴。笔者分析了压裂支撑剂的应用现状，总结了压裂支撑剂的最新进展及现场实验情况，包括高强度低密度支撑剂、高导流支撑剂、多功能支撑剂和智能支撑剂。结合我国油气勘探开发趋势，提出了压裂支撑剂的科技攻关和技术发展方向。围绕这些方向进行研究，尽快形成适应于我国油气储层的压裂支撑剂技术，对于提高油气产量，保障国家能源安全具有重要意义。 

Proppants for Fracturing Fluids: New Progress Made and Direction of Future Development

Proppant is a key material used in fracturing fluids to prop up artificial fractures for reservoir stimulation. It plays a key role in increasing the success rate of fracturing job and in improving the results of reservoir stimulation. A series of new proppants have recently been developed abroad and the ideas of the new proppant development is worth studying by us. In this paper the status quo of proppant application is analyzed and the newest progresses made in developing new proppants and field experiment of new proppants (including high strength low density proppant, high flow-conductivity proppant, multi-function proppant and intelligent proppant etc.) are summarized. Direction of scientific research and technical development is presented in this paper in connection with the trend of oil and gas exploration and development in China. Researches performed in this direction to develop proppant technologies suitable for fracturing oil and gas reservoirs in China is of great importance to the security of national energy resources.
