| description | The invention belongs to the technical field of natural gas extraction, and particularly provides an anti-freezing corrosion inhibition foam drainage scale inhibitor and a preparation method thereof.The anti-freezing corrosion inhibition foam drainage scale inhibitor is prepared from the following components by mass: 15-20% of an organic phosphoric acid corrosion inhibitor, 15-20% of an organic phosphine corrosion inhibitor, 25-30% of a quaternary ammonium salt corrosion inhibitor, 4-10% of a scale inhibitor, 3-5% of an emulsifier, 15-20% of an ampholytic surfactant, and 5-10% of a dispersingagent. The problems that when a large gas field aims at the problems of wellbore scaling, wellbore corrosion, gas well drainage gas recovery and the like, injected traditional scale inhibitors, corrosion inhibitors and foam drainage agents are single in agent performance, tedious in injection system and large in agent injection workload and do not have the anti-freezing effect are solved, the functions of scale prevention |
