Embodiment 1
[0060] A kind of high-efficiency rock-breaking agent (WGP) for stabilizing well walls, comprising 80 parts by mass of plant protein, 180 parts by mass of water, 50 parts by mass of phosphorus oxychloride (POCl 3 ) solution, 20 parts by mass of mercapto polyether polyol, 30 parts by mass of dioctyl sulfosuccinate, 16 parts by mass of sulfonating agent, n-hexane and a pH regulator.
[0061] A kind of manufacturing process of synthesizing this stable borehole wall efficient rock breaking agent (WGP):
[0062] 1) Weigh the vegetable protein and add it to water, let it stand at room temperature for 100 minutes, then shake it evenly at a constant temperature of 45°C;
[0063] 2) Take the above solution at 40°C, weigh the sulfonating agent, add it dropwise, and stir at constant temperature for 60 minutes;
[0064] 3) Heat the above solution in a water bath to 80° C., and adjust the pH value of the solution to 7 with a pH regulator;
[0065] 4) dissolving phosphorus oxychloride in n...
