PROPPANTS AND ANTI-FLOWBACK ADDITIVES INCLUDING KAOLIN CLAY |
摘要 |
A method of making a sintered ceramic proppant may include providing a kaolin clay. The kaolin clay may include an Al203 content no greater than about 46% by weight, and a K20 content no greater than 0.1 % by weight. The kaolin clay may have a particle size distribution such that greater than 70% of the particles have an equivalent spherical diameter of less than 0.5 microns as measured by Sedigraph, and a shape factor less than about 18. The method may further include blunging the kaolin clay, agglomerating the kaolin clay, and sintering the agglomerated kaolin clay to produce a sintered ceramic proppant. The kaolin clay may have an A-bob Hercules viscosity of at least about 3,300 rpm at 18 kilodyne-cm and 70% solids. |
