Abstract
Изобретение относитс к области нефтедобывающей промышленности, в частности к составам, используемым дл изол ции водопритоков в скважины . Цель изобретени - повьшгение устойчивости состава за счет снижени микробиологической деструкции в пластах, насьщенных микрофлорой. Дл этого в состав ввод т диалкилметилбензиламмоний хлорид (ДАМБАХ).. Состав имеет следующее соотношение компонентов , мае. %: гидролизованный полиакриламид 0,3-1,0; калийхромовые квасцы 0,001-0,030, ДАМБАХ 0,02-0,5, вода - остальное. Состав приготавливают путем растворени гидролизованного полиакриламида и калийхромовых квасцов в однопроцентном растворе ДАМБАХ. Данный состав позвол ет 1сл сократить потери прочности за счет .деструкции его реагентов под действием микрофлоры.The invention relates to the field of the oil industry, in particular, compositions used to isolate water inflows into wells. The purpose of the invention is to improve the stability of the composition by reducing microbiological destruction in the formations filled with microflora. For this purpose, dialkylmethylbenzylammonium chloride (DAMBAH) is introduced into the composition. The composition has the following ratio of components, May. %: hydrolyzed polyacrylamide 0.3-1.0; potassium chrome alum 0.001-0.030, DAMBAH 0.02-0.5, water - the rest. The composition is prepared by dissolving hydrolyzed polyacrylamide and potassium chrome alum in a 1% DAMBAH solution. This composition allows one to reduce the loss of strength due to the destruction of its reagents under the action of microflora.
Description
Изобретение относитс к нефтедобьшающей промышленности, в частности к составам дл изол 1щи водопритоков в скважины.The invention relates to the oil industry, in particular to compositions for isolating water inflows into wells.
Целью изобретени вл етс повышение устойчивости состава за счет снижени микробиологической деструкции в пластах, насыщенных микрофлорой .The aim of the invention is to increase the stability of the composition due to the reduction of microbiological destruction in reservoirs saturated with microflora.
