Abstract
The invention discloses a preparation method of special trenchless mud bentonite. The method comprises the following steps: drying natural magnesium aluminum silicate mineral serving as a raw material; grading the dried material; removing impurities such as stone blocks and the like; adding inorganic salt containing monovalence metal ions and mixing; carrying out smashing and modified treatment on the mixed raw material; adding a mixed additive formed by a plurality of organic and inorganic substances into the powder material; fully homogenizing and mixing; and packaging a finished product. According to the method, the production process is simplified and the mixed additive is added, so that the product can be directly used for the trenchless engineering and can adapt to different stratigraphic geology structures; and the adding of any other additive for performing adjustment actions is not required. As a result, the smooth proceeding of the trenchless engineering is guaranteed.
Description
Technical field
The present invention relates to the special-purpose mud preparation method for bentonite of a kind of non-excavation.
Background technology
The special-purpose mud wilkinite of non-excavation is take wilkinite as raw material, and the wilkinite raw ore is carried out being equipped with the composite additive processing after modification.This product have mud yield high, consider vector low, contain that sand is few, the with slurry dissolving is fast, need not add any other auxiliary agent in use procedure, be adapted at using in different geo-logical terrains.Can play and protect the borehole wall, equilibrium strata pressure, cooling and lubricating drilling tool, carry the effects such as drilling cuttings in the no-digging drilling process.
The mud wilkinite that uses in present domestic trenchless engineering mainly take the oil field with the mud wilkinite as main.Sodium modification has just been carried out to wilkinite usually with the mud wilkinite in the oil field, in use need to carry out the scene allotment by professional mud engineer by the stratum.And the common quantities of trenchless engineering is less, and operation in the open air mostly, seldom has to be equipped with professional mud engineer, and the present invention uses and mud wilkinite production technique angle from the scene, developed the special-purpose mud preparation method for bentonite of a kind of non-excavation.
Summary of the invention
The object of the present invention is to provide the special-purpose mud preparation method for bentonite of a kind of non-excavation, the present invention simplifies production technique and has added adding of mixed additive, product can directly be used in trenchless engineering, can be fit to the Different Strata geologic framework, do not need to add again any other additive and adjust, for trenchless engineering provides guarantee smoothly.
The present invention adopts following technical scheme to achieve these goals:
The special-purpose mud preparation method for bentonite of non-excavation take the natural magnesium aluminium silicate mineral as raw material, follows these steps to be prepared:
(1) the natural magnesium aluminium silicate mineral are carried out the drying fragmentation, dry rear material moisture is controlled at 2%-20%;
(2) with Impurity removals such as stones in the material of drying, control the dried material granular size at 2-50mm;
(3) add the inorganic salt of monovalent metallic ion to mix, the consumption of the inorganic salt of monovalent metallic ion is for doing the 0.5%-10% in ore deposit;
(4) this mixture is pulverized modification, the fineness of controlling the mixture pulverizing is controlled at 200 order content and reaches 80-97%;
(5) will be added by multiple inorganic, mixed additive that organism forms and process in powder fully homogenizing and mix, add-on is for processing the 0.1-5% of powder weight;
(6) finished product packing, the finished product.
The special-purpose mud preparation method for bentonite of non-excavation, the inorganic salt of described monovalent metallic ion comprise Li

The special-purpose mud preparation method for bentonite of non-excavation, the mixed additive in described the 5th step is that in Xylo-Mucine, polyacrylamide, magnesiumcarbonate, magnesium oxide, silicon-dioxide, aluminum chloride, modified starch, hydroxypropylcellulose, Sodium salts humic acids, tackifier for drilling fluid 80A-51, polyvinyl alcohol, the 2-6 kind forms.
Beneficial effect of the present invention:
The present invention simplifies production technique and has added adding of mixed additive, product can directly be used in trenchless engineering, can be fit to the Different Strata geologic framework, not need to add again any other additive and adjust, for trenchless engineering provides guarantee smoothly.
