Problems solved by technology

[0003] At present, the price of bentonite in the market varies according to the geographical location, and is basically maintained between 1000-2000 yuan / ton. The anti-seepage walls of large reservoirs and hydropower stations are products made of slurry made of sodium-based bentonite plus sodium hydroxide. Relatively high, about 60-100 yuan / m 3 , the price is high

Embodiment 1

[0025] A composite chemical mud material, comprising clay and chemical mud, the components of the chemical mud and their mass fractions are: 1 part of squash gum, 1 part of pregelatinized starch, 0.3 part of xanthan gum, 0.2 part of borax, and sodium hydroxide 0.3 part and preservative 0.1 part. Preservatives include one or more of paraformaldehyde or Blobber.

[0026] A preparation method of a composite chemical mud material, the steps are as follows:

[0027] (1) Add 1000g of water into 1000g of high-speed stirring device and add 1000g of squash gum, 1000g of pregelatinized starch, 300g of xanthan gum, 200g of borax and 300g of sodium hydroxide successively, and carry out high-speed stirring while adding materials;

[0028] Step (1) The speed of the high-speed stirring device for high-speed stirring is 2880 rpm.

[0029] Step (1) stirring time is 5min.

[0030] (2) Add 800g of clay and 100g of preservative successively to the agitated material obtained in step (1), and st...

Embodiment 2

[0034] A composite chemical mud material, comprising 0.4 parts of clay and chemical mud, the components of the chemical mud and their mass fractions are 0.6 part of squash gum, 1.1 part of pregelatinized starch, 0.1 part of xanthan gum, 0.1 part of borax, hydrogenated Sodium 0.2 part, preservative 0.3 part and water 1000 part.

[0035] The preparation process of the composite chemical mud material is the same as the first embodiment.

Embodiment 3

[0037] A composite chemical mud material, comprising 1.3 parts of clay and chemical mud, the components of the chemical mud and their mass fractions are 1.5 parts of squash gum, 1.8 parts of pregelatinized starch, 0.45 parts of xanthan gum, 0.3 part of borax, and Sodium 0.5 part and preservative 0.5 part and water 1000 part.

[0038] The preparation process of the composite chemical mud material is the same as the first embodiment.

[0039] Therefore, the present invention adopts the composite chemical mud material with the above structure and its preparation method, which has low cost and extremely low water loss rate and meets the needs of construction parties.

Abstract

The invention discloses a composite chemical slurry material. The composite chemical slurry material comprises clay and chemical slurry. The chemical slurry comprises sesbania gum, pregelatinized starch, xanthan gum, borax, sodium hydroxide and preservatives. The composite chemical slurry material has the advantages that by the composite chemical slurry material and a preparation method thereof, bentonite slurrying can be replaced, cost is low, water loss rate is extremely low, and requirements of constructors are met.

Description

technical field [0001] The invention relates to the technical field of mud production methods, in particular to a composite chemical mud material and a preparation method thereof. Background technique [0002] Bentonite is a kind of clay. Its main component is montmorillonite, which is a layered structure of hydrous aluminosilicate minerals. Bentonite gradually disperses in fresh water to increase the viscosity and shear force of the mud. The main function of bentonite is to increase the plastic viscosity, static shear force and dynamic shear force of the system, so as to enhance the suspension and carrying capacity of drilling fluid to cuttings; at the same time, reduce the filtration loss, form dense mud cake, and enhance wall building. Bentonite and water make up the mud used in the horizontal directional drilling process. During the horizontal directional drilling process, the mud has the functions of carrying and suspending cuttings, stabilizing the well wall, cooling a...
