Abstract One of the most important inputs for hydraulic fractures is the proppant. Although silica, ceramic, resin coated sands are used, the ultra-light weight proppants are preferred in some applications since they reduce settling, require low fluid viscosity to transport and allow an increased propped length. In this sense, we synthesized, characterized, and evaluated the performance of polymer proppants obtained from suspension polymerization in presence of micro- or nanofillers. The results obtained from resistance to organic solvents and from crush tests, showed that the composites prepared in presence of carbon black were the most promising. It is important to highlight the good performance with respect to the requirements for a hydraulic fracture: the results from the conductivity and permeability tests were similar to those of commercial polymeric and natural sand, and no generation of fines was observed in the crushing test.

超轻质支撑剂：新型支撑剂的合成、表征和性能。

摘要 水力压裂最重要的输入之一是支撑剂。尽管使用了二氧化硅、陶瓷、树脂涂层砂，但在某些应用中还是首选超轻质支撑剂，因为它们可以减少沉降，需要低流体粘度才能运输并允许增加支撑长度。在这个意义上，我们合成、表征和评估了在微米或纳米填料存在下悬浮聚合获得的聚合物支撑剂的性能。从耐有机溶剂和压碎试验中获得的结果表明，在炭黑存在下制备的复合材料是最有前途的。重要的是要强调在水力压裂要求方面的良好性能：
