A kind of preparation of water-soluble Cementing phenolic resin material, preparation process are as follows：
A, it feeds intake：The phenol, catalyst or formaldehyde that are weighed by quantitative number are put into reaction kettle, starting blender makes benzene
Phenol, catalyst or formaldehyde are mixed evenly, and are opened steam valve and are begun to warm up；
B, dropwise reaction：When reactor temperature is warming up to 80-90 DEG C, start that quantitative catalyst or formaldehyde is added dropwise,
Time for adding is 1-3.5 hours or so；If temperature in the kettle is warming up to 100-105 DEG C, answers steam off, continue to stir；
C, polycondensation reaction：After being added dropwise, material in kettle should be observed at any time, when finding that material starts emulsification, opened again
It opens preventing trace amount of steam to be kept the temperature, the reaction was continued at a temperature of 100-120 DEG C 2-4 hours；
D, after insulation reaction, increase steam is heated, temperature in the kettle heating, until stop stirring at 140-150 DEG C,
Steam off valve adjusts pipeline valve, starts the dehydration of nature normal pressure, should observe the flowmeter of wastewater storage tank at this time, and dehydrating amount is
The 8-10% of input material total amount；
E, it after reaching dehydration terminal, is then turned on stirring, opens cooling water valve, carry out chuck cooling, treat material temperature in kettle
After degree is less than 60 DEG C, stirring, cooling water valve are closed, carries out blowing, finally obtains the naval stores of light brown liquid state.

By the water-soluble Cementing phenolic resin product that the embodiment above 1-5 and preparation method are obtained through surveying
Examination obtains technical indicator listed in Table：
Naval stores prepared by the present invention is after tested：Appearance：Thick liquid, the active ingredient of light brown：40% aqueous solution,
Viscosity：15,000-25,000cp、pH：7.0-8.0, free phenol：5.5-6.5%, melt water are than 1:7-8, molecular weight 3500-
6000.Batch test is carried out through research, in terms of mud fluid and the oil-well cement mortar well cementation thickener added outside all
Accreditation, the thickening that alternative traditional acrylate polymer by with synergistic effect is formed with bentonite mixtures are arrived
Agent or non-ionic polyurethane class thickener, the sedimentation stability of mixture, pumpability and filling process is more preferable, and cost
Lower, using more convenient, solidification effect is significantly improved with efficiency, the oil-well cement solidification intensity higher after well cementation.
