11эобрете1гие относитс к горному делу, к средствам дл отбора кериа при бурении скпажин с сохранением пластовой среды.11 the invention relates to mining, to the means for selecting keria when drilling downs with preservation of the formation medium.
Цель изобретени - повышение надежности консервации и безопасности хранени за счет увеличени стойкости покрыти к воздействию сероводорода .The purpose of the invention is to increase the reliability of conservation and storage safety by increasing the resistance of the coating to the effects of hydrogen sulfide.
Дл реализации предлагаемого способа консервации керна на поверхность керна нанос т защитный герметичный слой полимеризующегос состава . В качестве ингредиентов полимеризующегос состава примен ют крем нийоргаиический каучук,стабилизированный аэросилом, и отверждаемый катализатором в виде раствора дибутил- д лаурата олова Д1 этилси.чика 1 с-32 , в отношении по массе 1:1.In order to implement the proposed method of preserving the core, a protective hermetic layer of the polymerizing composition is applied onto the surface of the core. The ingredients of the polymerizable composition are silicon-silicone rubber, stabilized with aerosil, and catalyst-curable in the form of a solution of dibutyl-tin of laurate of tin D1 ethyl s.ch.
Необходимое условие ;.Ц1 иолучоь м требуемой прочности и стойкости покрьшающего керн сло к воздействию сероводорода достигаетс при способности состава сохран ть текучести (жизнеспособность)на прот жении от трех до дес ти часов, что обеспечиваетс количестпом катализатора, принимаемого из расчета 2,5-5 г на 100 г каучука.The necessary condition; .1 and the desired strength and durability of the core layer to the effects of hydrogen sulfide is achieved with the ability of the composition to maintain yield (viability) for three to ten hours, which is provided by the amount of the catalyst, taken at a rate of 2.5-5 g per 100 g of rubber.
Да1П{ое соотношение подтверждаетс экспериментальными датп,1ми в таблице .Yes1 {ratio is confirmed by experimental dates, 1 in the table.
Как видно из таблицы, р.аиболее оптимальным соот1Ю111ением, при котором компаунд остаетс жизнеспособным, ивпиетсл соотношение 100 г каучука и 2,5-5,0 катализатора.As can be seen from the table, the most optimal match for which the compound remains viable is a ratio of 100 g of rubber and 2.5-5.0 catalyst.
