| The raw material of ceramic proppant is sintered from bauxite and other additives, and its mineral composition, is aluminum oxide, silicate and iron - titanium oxide, it is round, and has high strength, suitable for the fracturing of deep oil and gas stratum with high closure pressure, for the middle and deep well, it can be used to enhance the conductivity as the trailing proppant.
?Fracturing fluid and additive mix together and then are pumped into the stratum, after that it will produce cracks at the same time which will carry the fracturing proppant inside, after flowback fracturing proppant will keep cracks open. The corresponding cost ratio is: pumping fluid 46%, fracturing proppant 25%, fracturing chemicals materials 19%, acid 10%.
?Fracturing proppant's role is to keep created cracks open after there have cracks, so its strength is essential, fracturing proppant must enough to withstand closure pressure. |
