| titleOfInvention | A kind of water-based fracturing fluid gelatinizer and its production method |
| abstract | The invention discloses a kind of water-based fracturing fluid gelatinizer and its production method, and in particular to a kind of high temperature resistance reaches 250 DEG C of water-based fracturing fluid gelatinizer and its production method.The technical problem to be solved is that conventional water-based fracturing fluid gelatinizer endurance of cutting is poor, and salt tolerance is poor, and cull absorption blocks serious, it is impossible to superhigh temperature resistant.The present invention is prepared from by the raw material of following mass percent：（a）13 28% acrylamide；（b）8 10% PAA；（c）2 10% methyl propane sulfonic acid of 2 acrylamide 2；（d）1 2.5% fat of acrylic acid 18；（e）Surplus is water.Using the present invention after such technical scheme, high temperature resistant, soluble, pollution-free, fanout free region, take that husky performance is good, especially resistance to elevated temperatures is good, can be resistant to 250 DEG C of high temperature, be adapted to the pressure break of high-temperature stratum, with higher endurance of cutting, sand is taken and without residue with high. |
