Abstract
The invention provides mud bentonite for well drilling, which comprises the following steps: the method comprises the following steps: screening and purifying bentonite raw materials mined from bentonite ores to remove impurities; step two: crushing a bentonite raw material, adding the crushed bentonite into the crushed bentonite for stirring, and adding sodium hydroxide into water for pH detection when the water is added to ensure that the pH value reaches 8-12 to obtain bentonite paste with the granularity reaching clay level; step three: adding an acidifier into the bentonite paste for acidification modification; step four: washing and filtering the acidified bentonite paste; step five: adding a sodium agent into the bentonite paste, stirring for sodium treatment, and keeping the temperature at 100 ℃ all the time; step six: filtering and drying the sodium-modified bentonite; step seven: and (4) crushing, grinding and packaging the filtered and dried bentonite. Thereby reducing the production cost, improving the quality of the produced product and improving the modification effect.
Description
Technical Field
The invention relates to the field of bentonite manufacturing, in particular to mud bentonite for well drilling.
Background
The bentonite is a layered clay material and has unique mineral structure and crystallization chemical property, the natural bentonite mainly takes calcium-based montmorillonite as a main material, the sodium-based montmorillonite is relatively less, and the sodium-based montmorillonite has a plurality of excellent properties such as good suspension property, high dispersibility, higher cation exchange capacity and the like compared with the calcium-based montmorillonite. The existing mud bentonite has high production cost and is not strict during production, thereby reducing the production quality and the modification effect. Therefore, there is a need to provide a mud bentonite for well drilling to solve the deficiencies of the prior art.
Disclosure of Invention
Aiming at the problems, the mud bentonite for well drilling provided by the invention adopts acrylic acid carbonate as a sodium treatment agent, so that the production cost is reduced, the quality of a produced product is improved by detecting the pH of added water, filtering the product for many times and controlling the temperature during production, and the modification effect is improved by adopting benzoic acid as an acidifier.
In order to solve the problems, the invention provides mud bentonite for well drilling, and the preparation process of the bentonite comprises the following steps:
the method comprises the following steps: screening and purifying bentonite raw materials mined from bentonite ores to remove impurities;
step two: crushing a bentonite raw material, adding the crushed bentonite into the crushed bentonite for stirring, and adding sodium hydroxide into water for pH detection when the water is added to ensure that the pH value reaches 8-12 to obtain bentonite paste with the granularity reaching clay level;
step three: adding an acidifier into the bentonite paste for acidification modification;
step four: washing and filtering the acidified bentonite paste;
step five: adding a sodium agent into the bentonite paste, stirring for sodium treatment, and keeping the temperature at 100 ℃ all the time;
step six: filtering and drying the sodium-modified bentonite;
step seven: and (4) crushing, grinding and packaging the filtered and dried bentonite.
The further improvement lies in that: the sodium reagent is acrylic acid carbonate.
The further improvement lies in that: the acidifier is benzoic acid and the addition amount is 15-25 parts.
The further improvement lies in that: 5-15 parts of alkyd resin is added before the acidifier is added for stirring.
The invention has the beneficial effects that: the sodium treatment agent adopts acrylic acid carbonate, so that the production cost is reduced, the quality of the produced product is improved by detecting the pH of the added water, filtering the product for many times and controlling the temperature during production, and the acidifying agent adopts benzoic acid, so that the modification effect is improved.
Detailed Description
For the purpose of enhancing understanding of the present invention, the present invention will be further described in detail with reference to the following examples, which are provided for illustration only and are not to be construed as limiting the scope of the present invention.
