Description
Изобретение относитс к производству тампонажных смесей, в частности дл цементировани высокотемпературных скважин , и может быть использовано в нефт ной и газовой промышленности.The invention relates to the production of cement mixtures, in particular for the cementing of high temperature wells, and can be used in the oil and gas industry.
Известны тампонажные смеси дл указанных целей, содержащие в качестве основы цемент и химическую добавку-замедлитель , например КМЦ 1.Known cement mixtures for these purposes, containing as the basis of cement and chemical additive-retarder, for example CMC 1.
Однако указанна добавка-замедлитель, удлин сроки схватывани смеси, при высоких температурах в скважине неэффективна .However, this moderator additive, lengthening the setting time of the mixture, is not effective at high temperatures in the well.
Наиболее близкой по составу из уже известных тампонажных смесей вл етс тампонажна смесь, содержаща цемент и добавку-замедлитель - виннокаменную кнслоту 2.The closest in composition of the already known cement mixtures is the cement mixture containing cement and the inhibitor additive - the tartar cell 2.
Однако данна смесь характеризуетс удлиненными сроками схватывани , имеет при высоких температурах низкую прокаливаемость .However, this mixture is characterized by an extended setting time, has a low hardenability at high temperatures.
Целью изобретени вл етс создание тампонажной смеси дл применени при температуре 75-150° С, котора в этих услови х имела бы удлиненные сроки схватывани и нормальную прокачиваемость.The aim of the invention is to create a grouting mixture for use at a temperature of 75-150 ° C, which under these conditions would have an extended setting time and normal pumpability.
Это достигаетс применением тампонажной смеси на основе цемента (99,70-99,99 вес. %) и добавки-замедлител - солей 1-оксиэтилиденфосфановой кислоты, например тринатриевой или трикалиевой солиThis is achieved by using a cement-based cement mix (99.70-99.99 wt.%) And a retarding additive — salts of 1-hydroxyethylidenephosphanic acid, such as trisodium salt or tri-potassium salt.
1-оксиэтилиденфосфановой кислоты (0,01 - 0,30 вес. %).1-hydroxyethylidenephosphonic acid (0.01 - 0.30 wt.%).
Дл получени тамнонажных смесей беретс 500 мл воды и 1 кг цемента дл «гор чих скважин (например, Новороссийского завода), добавл етс 0,01-0,3% солей 1-оксиэтилиденфосфановой кислоты или 0,1-0,3% солей синтетической винной кислоты (дл сравнени ), перемешиваетс , затем замер етс плотность и растекаемостьTo obtain the cement mixtures, 500 ml of water and 1 kg of cement are taken for "hot wells (for example, Novorossiysk plant), 0.01-0.3% of salts of 1-hydroxyethylidenephosphanic acid or 0.1-0.3% of salts of synthetic tartaric acid (for comparison), stirred, then the density and flow
и ставитс в автоклав дл определени сроков схватывани .and placed in an autoclave to determine the setting time.
Полученные результаты приведены в таблице.The results are shown in the table.
Как видно из таблицы, соль 1-оксиэтилиденфосфановой кислоты вл етс более эффективным замедлителем сроков схватывани цементного раствора, чем известна , улучшает прокачиваемость цементного раствора и повышает прочность цементного камн .As can be seen from the table, 1-hydroxyethylidenephosphonic acid salt is a more effective time setting agent for cement slurry than is known, improves the pumpability of the cement slurry and increases the strength of the cement stone.
Внедрение предложенной добавки позвол ет значительно улучшить крепление нефт ных и газовых скважин.The introduction of the proposed additive can significantly improve the fixing of oil and gas wells.
