DETAILED DESCRIPTION

[0056] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0057] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0058] Embodiment 1:

[0059] A geological drill pipe antifreeze formula, comprising: 40-50% ethylene glycol, 10-15% propylene glycol, 5-10% calcium chloride, 5-10% magnesium chloride, 5-10% organic antifreeze, 1-3% preservative, 1-3% rust inhibitor, 1-3% stabilizer, 0.1-0.5% nanoparticles, 0.1-0.5% antimicrobial agent, 0.1-0.5% corrosion inhibitor, 0.1-0.5% defoamer, and the balance of deionized water;

[0060] Wherein, the nanoparticles are graphene oxide or multi-walled carbon nanotubes, and the organic antifreeze agent is polyethylene glycol or polypropylene glycol;

[0061] The preservative is sodium benzoate, the rust inhibitor is sodium nitrate, the stabilizer is EDTA, the antimicrobial agent is isothiazolinone, the corrosion inhibitor is benzotriazole, and the defoaming agent is silicone oil.

[0062] This antifreeze formula, by adding nanoparticles, can increase the thermal conductivity of the liquid, help the antifreeze to transfer heat at low temperatures, and reduce the possibility of freezing; by adding organic antifreeze, these high molecular weight organic compounds have low toxicity and good biodegradability, which can improve the environmental performance of the antifreeze; by adding antimicrobial agents, it can prevent the growth of microorganisms during long-term storage or use.

[0063] In order to better evaluate the performance of antifreeze, the following experiment is designed:

[0064] Experimental steps:

[0065] ①Sample preparation:

[0066] According to the improved formula, 5 groups of antifreeze samples with different proportions were prepared, with a total volume of 1 liter in each group. The proportions of other ingredients were kept unchanged, and the proportions of the main antifreeze agents ethylene glycol and propylene glycol, as well as the proportion of graphene oxide were adjusted.

[0067] ② Freezing point test:

[0068] Place each sample in a low temperature thermostat, set different temperatures (-20℃~-50℃), and keep each temperature for 24 hours. Observe and record the freezing of each sample at different temperatures to determine the freezing point.

[0069] ③ Thermal conductivity test:

[0070] Use a thermal conductivity meter to measure the thermal conductivity of each sample at room temperature. Record the data and compare the effects of different ratios on thermal conductivity.

[0071] ④Corrosion test:

[0072] Immerse the metal sheet (iron, copper, aluminum) in each sample and keep it at the set temperature for 72 hours. Observe the mass change and surface condition of the metal sheet to evaluate the degree of corrosion.

[0073] ⑤Microbial growth test:

[0074] The sample is inoculated with microorganisms and cultured at room temperature for a certain period of time. The growth of microorganisms is observed and counted under a microscope to evaluate the antimicrobial effect.

[0075] ⑥Foam performance test:

[0076] Use a stirring device to generate foam under high-speed stirring, and observe the speed and stability of foam generation. Record the time it takes for the foam to disappear and evaluate the effect of the defoamer.

[0077] Reference Figure 9-11 , the experimental data are as follows (data rounded):

[0078] Sample No. Ethylene glycol (%) Glycerol(%) Graphene oxide (%) Polyethylene glycol (%) Freezing point(℃) Thermal conductivity (W / mK) Corrosion weight loss (mg) Microbial growth Foam disappearance time(s) A 50 5 0.1 5 -38 0.6 2 No significant growth 28 B 45 10 0.4 10 -47 0.62 1 Slight growth 24 C 40 15 0.5 10 -49 0.65 0 No growth 20 D 45 10 0.3 10 -43 0.58 3 Slight growth 32 E 40 10 0.2 8 -39 0.55 4 Significant growth 35

[0079] From the above, it can be seen that the formula with sample number C has better effect, so preferably, the addition ratio of ethylene glycol is 40%, the addition ratio of propylene glycol is 15%, the addition ratio of graphene oxide is 0.5%, and the addition ratio of polyethylene glycol is 10%.
