摘要
According to the performances of all common domestic high-strength ceramsites, the common domestic proppants cannot meet the requirements of the fracturing and acidizing technology in Tahe oilfield to proppant because they have bad acid-resistance, higher density and lower strength. For this reason, a new high-strength proppant H-l is developed for the oilfield. The measuring results of its performance show that, the acid solubility of the proppant is 1.6% ,the breaking rate of it is 2.1% at 86 MPa. The proppant can make formation have higher flow conductivity under high-temperature, high closure stress and acidic environment, and it can well meet the requirements of the fracturing and acidizing technology in Tahe oilfield.
