| titleOfInvention | A kind of polymerization species barium strontium calcium antisludging agent and preparation method thereof |
| abstract | The invention discloses a kind of polymerization species barium strontium calcium class antisludging agents and preparation method thereof, by three kinds of itaconic acid, vinyl sulfonate, acrylamide substances polymerization reaction occurs for the polymerization species barium strontium calcium antisludging agent, and be prepared by initiation reaction and cross-linking reaction, then the polymerization species barium strontium calcium antisludging agent powder is obtained through drying, granulation.The polymerization species barium strontium calcium class antisludging agent antiscaling effect is good, the inorganic compounding dirt for the solubility very little being precipitated from water can effectively be prevented, it is environment-friendly and low-toxicity, solves the inorganic scale on Oilfield Pipelines surface, equipment surface, surface of stratum deposition, it has important practical significance to the recovery ratio for improving oil well, and the polymerization species barium strontium calcium antisludging agent preparation method is simple, and it is extensive to prepare raw material sources, reduces production cost. |
