Description

This invention relates to the stabilization of clay and other suspensions, in particular drilling fluids.

The purpose of the invention is to increase the effectiveness of starch-containing reagent to reduce the water loss of the drilling fluid while reducing the cost of the reagent.

The composition for the preparation of starch-containing reagent includes grain basis and agrimus - waste of furfural production from corn cobs in the following ratio of ingredients, wt.% (Calculated on dry weight):

Grain base 70-Q5 Agrimus waste from the production of furfural from corn cobs 5-30 Agrimus contains, in wt.% (Calculated on the dry matter): Modified cellulose45 Lignin30 Free furfurol 0.5 Nitrogen0.6 PhosLor3.0 Capium1, 5 Calcium1.9

Organic acids (in terms of acetic acid) 3.0 Reducing substances 3.9 pH 3.0 In composition, it is a chiologically active mineral-organic additive that can intensively borrow with components of rich raw material.

The introduction of up to 30% of agrimus (dry matter) significantly changes the composition of the raw material being processed by comparing} 5 with the composition of the starting material used in the production of extrusion starch reagent ECR. (Table 1).

From these data of Table 1, it can be seen that the marketing composition of the composition substantially differs from the traditional one — a low content of starch, nitrogenous substances, fat, carbohydrates and an increased content of ash elements, incl. bi-and polyfunctional, capable of interacting with polysaccharides and nitrogenous substances (calcium and phosphorus). The increased content of potassium compounds activates the chemical transformation of polysaccharides.

A change in the composition of the composition to obtain a starch-containing reagent does not require a significant change in its processing technology as compared with the ERS technology. Additionally, only the agrimus feeder is included in the processing line. Mixing it with the starch-containing material 40 is carried out during their joint transportation and grinding.

The production of the reagent is carried out as follows.

not 350 mm and the diameter of the die aperture is 2.5 mm, the screw rotation frequency is 40 and 100 rpm. The resulting extrudate was crushed, sieved through a sieve with cells of 0.5 xO, 5 mm and subjected to analysis.

Data illustrating the effect of the obtained reagent on the technological parameters of a water-based mud mud is given in Table 2.

Analysis of the data presented in Table 2 shows that the introduction of agrimas into the starch-containing material makes it possible to obtain a reagent that is capable of actively reducing the yield of clay suspensions. At the same time, the introduction of agrimus below 5% by weight of the starch-containing material slightly changes the physicochemical properties of the extrudate. On the other hand, adding it in an amount of more than 30% makes it difficult to process the mixture in an extruder due to a sharp decrease in its plasticity and an increase in the load on the electric motor. In connection with this, the limits of the addition of agrimus to the cereal base should be from 5 to 30% (previously 20-25%).
