Замедл ющее действие этих реагентов на и.ементны {})створы неоднозначно, т.е. они моrj T как замедл ть, так и ускор ть сроки схватывани растворов. Известен способ обработки глини . буровых и цементных растворов г|утем введени реагентов-понизителе в зкости 2 .

Реагент имеет высокую стоимос Целью изобретени вл етс повышение эффективности обработки за счет повышени разжижаю щх свойств растворов. Поставленна цель достигаетс тем, что согласно способу обработки глинисных буровых и цементных растворов путем введени реагента-понизител в зкости, в качестве последнего растворы содержат кубовые остатки производства синтетического глицерина, содержащие, мас.%: Полиглидерины 60-67 Хлористый натрий 8-13 ВодаОстальное в количестве 0,1 - 0,5 % к массе раствора. Причем полиглицерины содержат следующие компоненты, мас.%: Глицерин8,0-15,0 Диглицерин80,0-85,0 Триглицерин 3,0-4,0 Тетраглицерин 1,5-2,0 Пентаглицерин 0,5-1,0 Основным активным компонентом полиглицеринов вл етс диглицерин, что подтверждаетс результатами сравнительной оценки вли ни различ ных глицеринов на свойства растворов . В табл. 1 представлены свойства глинистого раствора, содержащего 40% глины и 60% воды, плотностью ,1,32 г/см без добавок (исходный раствор) и с добавками глицерина, диглицерина и полиглицерина. Как видно из табл. 1, снижение относительной в зкисти исходных глинистых растворов происходит в основном за счет добавки диглицерина. Добавки остальных компонентов в тех же концентраци х оказывают незначительное вли ние на снижение в зкости бурового раствора. В табл. 2 представлены свойства цементных растворов с В/Ц 0,5 без добавок и с добавками глицерина, диглицерина и полиглицерина. Из данных табл. 2 следует, что основное вли ние на снижение растекаемости цементного-раствора оказывает диглицерин. / Отход - это густа жидкость теМ но-коричневого цвета, хорошо раствор юща с в воде.

Результаты обработки глинистого раствора высокой в зкости ОПГ и ПФЛХ в табл. 5, I Как видно из данных табл. 4 и 5, отходы производства синтетического глицерина более эффективно повышают растекаемость, замедл ют сроки загустевани и схватывани цементных и снижают в зкость глинистых растворов , чем полифенолы. Цементный камень , содержащий полиглицерин, имеет более высокую прочность. При добавках предлагаемого реагента образуетс мало пены, о чем можно судить по плотности растворов. Так при добавках ОПГ плотность растворов снизилась по сравнению с исходными на 0,02-0,04 г/см, а плотность растворов с добавками полифенолов на 0,02-0,10 г/см.

There are known methods for treating clay drilling and cement mortars by introducing viscosity reducing agents (sulfite alcohol bar, condensed bard sulfite, nitrolignin, etc.) However, in this method of processing sulfite alcohol bard and condensed sulfite alcohol bard, they do not effectively reduce the viscosity of liquids . The retarding effect of these reagents on i.ementny {}) cross sections is ambiguous, i.e. they can both slow down and accelerate the setting time of the solutions. A known method of processing clay. drilling and cement mortars r | we thaw the introduction of reagents viscosity 2. However, the addition of PFLH does not effectively increase the flowability, slows down the setting time of cement and reduces the viscosity of clay solutions. When preparing rast | orov with this additive is formed. abundant foam, therefore additional scavengers should be added to the solution. To prepare the PFLC solution, prolonged mixing (1.0-1.5 h) in clay mixers or cementing aggregates is necessary. The reagent has a high cost. The aim of the invention is to increase the processing efficiency by increasing the diluting properties of the solutions. The goal is achieved by the fact that, according to the method of processing clay drilling and cement mortars by introducing a viscosity reducing agent, the latter solutions contain bottom residues of synthetic glycerin production, containing, in wt%: Polygliderine 60-67 Sodium chloride 8-13 Water the amount of 0.1 - 0.5% by weight of the solution. Moreover, polyglycerols contain the following components, wt.%: Glycerin 8,0-15,0 Diglycerol 80,0-85,0 Triglycerol 3,0-4,0 Tetraglycerol 1,5-2,0 Pentaglycerin 0,5-1,0 The main active The component of polyglycerols is diglycerin, which is confirmed by the results of a comparative assessment of the effect of various glycerols on the properties of solutions. In tab. 1 shows the properties of the mud solution containing 40% clay and 60% water, density, 1.32 g / cm without additives (initial solution) and with the addition of glycerin, diglycerin and polyglycerol. As can be seen from the table. 1, the decrease in the relative viscosity of the original clay solutions occurs mainly due to the addition of diglycerin. Additions of the remaining components at the same concentrations have a negligible effect on reducing the viscosity of the drilling fluid. In tab. 2 presents the properties of cement mortars with a / C 0.5 without additives and with the addition of glycerol, diglycerin and polyglycerol. From the data table. 2, it follows that diglycerol has the main effect on reducing the flowability of cement mortar. / Waste is a thick, brown-colored liquid that dissolves well in water. Depending on the method of isolation, the solution of polyglycerol has a pH from 10 to 4. For a comparative evaluation of the effectiveness of the known and proposed additives, cement slurries were prepared that differ from each other in the content of additives in each solution (Table 3). The tests were carried out under the same conditions. according to GOST 1581-78. Solutions; tested for conditions of cold (T) and hot (T 75 ° C) wells. The test results of cement mortars are presented in table. 4. The results of processing the high viscosity mud solution of OPG and PFLH in table. 5, I As can be seen from the data table. 4 and 5, waste products from the production of synthetic glycerin more effectively increase the flowability, slow down the time of thickening and setting of cement and reduce the viscosity of the clay solutions than polyphenols. Cement stone containing polyglycerol, has a higher strength. With the addition of the proposed reagent, little foam is formed, which can be judged by the density of the solutions. So with the addition of OPG, the density of solutions decreased by 0.02-0.04 g / cm compared to the initial ones, and the density of solutions with the addition of polyphenols decreased by 0.02-0.10 g / cm. The reagent dissolves well in water and is significantly cheaper than polyphenols. upif cementing cold wells is not recommended to introduce the proposed additive in an amount of more than 0.1 wt.%, because the setting time of cement slows down dramatically.
