陶粒压裂支撑剂研究进展

Research Progress on Ceramic Fracturing Proppants

水力压裂是应用于石油天然气行业中的一种有效增产措施。随着非常规油气藏的发展,其已成为我国亟待攻克的技术难点之一。而压裂支撑剂是水力压裂过程中的关键材料,即用于支撑裂缝从而提高油气藏渗透率的球形颗粒。文章综述了国内外陶粒支撑剂的研究现状及发展趋势,重点介绍了铝矾土基和高岭土基压裂支撑剂的研究进展以及压裂支撑剂的制备工艺。

Hydraulic fracturing is an effective technique applied to the petroleum and gas industry. With the development of untraditional reservoir, hydraulic fracturing has become one of the technical difficulties for our country to overcome urgently. Fracturing proppants are small spherical particles used to improve the reservoir permeability, which prop fractures and then improve the oil and gas fracture permeability. This paper reviews the current situation and prospect of ceramic proppants with an emphasis on the research progress of bauxite-based and kaolinite-based fracturing proppants and the preparation processes of fracturing proppants.
