Embodiment 1

[0024] Dissolve 300g of methyl glucoside in 200g of water, add 0.5g of anhydrous zinc chloride, add dropwise 60g of hydrochloric acid with a concentration of 31% while stirring, after the addition is completed, heat up to 70°C, and keep the reaction in airtight heat preservation for 2 hours. Add 60g of Na to it 2 SO 3 , stir evenly, open the door and heat up to 90°C, and react for 1 hour. The methyl glucoside compounds shown in the following formula can be obtained:

[0025]

[0026] In addition, in other embodiments, as long as the amount of zinc chloride added is a catalytic amount, this is the choice of conventional technical means for those skilled in the art, and it can be obtained without any creative work, for example, making the reaction The concentration of zinc chloride in the system is at the ppm level to achieve the catalytic effect, so as to realize the smooth progress of the halogenation reaction step.

Embodiment 2 to Embodiment 4

[0028] In Example 2 to Example 4, the experimental data for the preparation of the methyl glucoside compounds are shown in Table 2 below:

[0031] Preparation of lubrication inhibitor for drilling fluid of the present invention

Embodiment 5

[0033] In this embodiment, the mass ratio of the methyl glucoside compound, bactericide and antioxidant is: methyl glucoside compound: bactericide: antioxidant=1:0.0001:0.0001. The bactericide is quaternary ammonium salt bactericide 1227, and the antioxidant is sodium bisulfite. When preparing the lubrication inhibitor for drilling fluid in this embodiment, the methyl glucoside compound, the quaternary ammonium salt fungicide 1227 and sodium bisulfite were added according to the above ratio, pulverized and mixed uniformly.

The invention discloses a methyl glucoside compound for drilling fluid, and a preparation method of the methyl glucoside compound; meanwhile, the invention provides a lubrication inhibitor containing methyl glucoside compound for drilling fluid; the lubrication inhibitor is composed of methyl glucoside compound, bactericide and antioxidant, has strong inhibitive ability and favourable lubricity, has no side effect on drilling fluid property, has no negative effect on other drilling operation programs and is capable of biodegradation.

Description

technical field [0001] The invention relates to a methyl glucoside compound, a preparation method of the methyl glucoside compound and a lubrication inhibitor for drilling fluid containing the methyl glucoside compound. Background technique [0002] With the expansion and deepening of oil and gas exploration and development, the intensity of drilling and development has been increasing, the difficulty of drilling has increased, and the complexity of drilling has become more prominent. There are more and more wells with special conditions such as deep wells, ultra-deep wells, directional wells, highly deviated wells, horizontal wells, multi-bottom wells, and slim hole wells, and the drilling speed needs to be greatly increased. Therefore, the increase in drilling difficulty also puts forward higher requirements for drilling fluid lubricants. [0003] Currently commonly used lubricants for drilling fluids include mineral oils, modified animal and vegetable oils, surfactants, ...
