Abstract
1. ТАМЮНАЖНАЯ СМЕСЬ, включающа портландцемент и карбонатную добавку, отличающа с тем, что, с целью увеличени прочности цементного камн , снижени водоотдачи и плотности приготавливаемого раствора, она в качестве карбонатной добавки содержит карбонатно полимерный шлам, вл ющийс отходом туковой промьшшен- ности, при следующем соотношении компонентов, мас.%: Портландцемент 70-50 Карбонатно-1. TAMUNA MIXTURE, including Portland cement and carbonate additive, characterized in that, in order to increase the strength of the cement stone, reduce the water loss and density of the prepared solution, it contains carbonate polymer slime as carbonate additive, the following ratio of components, wt.%: Portland cement 70-50 Carbonate
Description
1 Изобретение относитс к технологии креплени нефт ных и газовых скважин, в частности к тампонажным смес м, примен емым при тампонировании скважин. Целью изобретени вл етс умень шение .значений плотности и водоотдачи цементно-меловых тампонажных растворов и увеличение прочности получаемого камн . Дл приготовлени смеси используют карбонатно-полимерный шлам, вл ющийс отходом производства при тфрцессах очистки воды и регенерации каустической соды. Тампонажный раствор готов т затворением цемен8 та на заранее приготовленной карбонатно-полимерной суспензии. При приготовлении тампонажного раствора из названной смеси с соотношением в ней цемент: карбонатно-полимерный шлам 70:30, 60;40, 50:50 и воды, вз той в отношении к смеси соответственно 0,6; 0,7 и 0,8 получают раствор удовлетворительной плотности с низкой водоотдачей. В табл.1 и 2 представлены сравнительные данные свойств раствора и камн из предлагаемой и известной смесей на базе цементов дл холодных и гор чих скважин соответственно . 1 The invention relates to the technology of mounting oil and gas wells, in particular to cement mixtures, used in well packing. The aim of the invention is to reduce the values of density and yield of cement-chalk cement slurries and increase the strength of the resulting stone. For the preparation of the mixture, carbonate-polymer sludge is used, which is a waste product during water purification processes and caustic soda regeneration. The cement slurry is prepared by mixing cement on a preformed carbonate-polymer slurry. When preparing the cement slurry from the mixture with a ratio of cement: carbonate-polymer slurry 70:30, 60; 40, 50:50 and water taken in relation to the mixture, respectively, 0.6; 0.7 and 0.8 get a solution of satisfactory density with low yield. Tables 1 and 2 present comparative data of the properties of the solution and stone from the proposed and known mixtures based on cements for cold and hot wells, respectively.
