Изобретение относитс к тампо- нажным растворам, используемым дл креплени нефт ных, газовых и паро- нагнетательных скважин при температурах до 200 С..The invention relates to tamper solutions used to mount oil, gas and steam injection wells at temperatures up to 200 ° C.
Цель изобретени - увеличение сроков схватьшани в интервале температур 160-200 С и увеличение прочности цементного камн .The purpose of the invention is to increase the time of skvvshan in the temperature range of 160-200 C and increase the strength of the cement stone.
Готовили тампонажный раствор пу- тем тщательного перемешивани цемента с водой затворенй , в которую предварительно введено необходимое количество реагента. По конусу АзНИИ определ ли растекаемость раст вора. Готовый раствор помещали в автоклав и определ ли его сроки схва- тьюани при определенных услови х.The cement slurry was prepared by thoroughly mixing the cement with shutter water, in which the required amount of reagent was preliminarily introduced. According to the AzNII cone, the spreadability of the plant was determined. The prepared solution was placed in an autoclave and its timing was determined under certain conditions.
Из этого же раствора готовили образцы в виде призм 2«2«10 см. Ко- торые твердели в течение суток. После 24 ч твердени образцы испытывали на прочность.- Сравнительные результаты приведены в таблице.From the same solution, samples were prepared in the form of prisms 2 2 2 10 10 cm. Which hardened during the day. After 24 hours of hardening, the samples were tested for strength. - Comparative results are shown in the table.
Пример 1. Дл приготовле- ни предлагаемого тампонажного раствора 730 г цемента затвор ли 267 мл воды, в которой предварительно раствор ли 3 г СДБ. Помещали раствор в автоклавы и определ ли сроки схваты вани . Через сутки твердени в заданных УСЛОВИЯХ определ ли прочностExample 1. For the preparation of the proposed cement slurry, 730 g of cement was sealed with 267 ml of water, in which 3 g of DMB was previously dissolved. The solution was placed in autoclaves and the timing of the vanilla was determined. After one day of hardening, under specified conditions, the strengths were determined

Остальные опыты проводили аналогично .The rest of the experiments were carried out similarly.
Пример 2. 730 г ШПЦС-200 затвор ли 267 мл воды, в которой предварительно раствор ли 3 г щелока . Результаты испытаний приведены в таблице.Example 2. 730 g of SHPSS-200 were shut off with 267 ml of water, in which 3 g of lye was previously dissolved. The test results are shown in the table.
Лигносульфоновые щелока - это жидкость темно-коричневого цвета плотностью 1,26-1,28 г/см.Lignosulfonic liquor is a dark brown liquid with a density of 1.26-1.28 g / cm.
Лигносульфоновые соединени известны как замедлители, но наличие в щелоках Сахаров и их производных с фурфуролом преп тствует сбраживанию Сахаров, в результате чего наблюдаетс эффект.термостойкости реагента , увеличени замедл ющей способности и повышени прочности тампонажного камн с применением щелоков. Кроме того, резкое замедление сроков схватьшани и уменьшение расхода 4зеагента наблюдаетс видимо, за счет комплексных соединений, которые образуютс при взаимодействии реагента с веществами, составл ющими в жущее . Количество сульфоновых щелоков , приход щихс на 1т целлюлозы, составл ет 8-9 м и вл етс неутилизируемым .Lignosulfonic compounds are known as moderators, but the presence of Sugars in liquors and their derivatives with furfurol interferes with the digestion of Sugars, as a result of which the thermal resistance of the reagent is observed, an increase in the retarding ability and an increase in the strength of the cement stone with the use of liquors. In addition, a sharp deceleration of the time of skvdashan and a decrease in the consumption of 4th agent is observed, apparently, due to the complex compounds that are formed during the interaction of the reagent with the substances that make it up. The amount of sulphonic liquors per 1 ton of cellulose is 8-9 m and is non-utilizable.
