Description
Изобретение относитс к бурению нефт ных и газовых скважин на нефть и газ, в частности к реагентам дл обработки буровых растворов.The invention relates to the drilling of oil and gas wells for oil and gas, in particular to reagents for the treatment of drilling fluids.
Наиболее близким к предлагаемому составу вл етс состав, содержащий 5,0- 20,0% полиакрилонитрила и 95-80% щелочного раствора гуматов натри или кали .Closest to the proposed composition is a composition containing 5.0-20.0% polyacrylonitrile and 95-80% alkaline solution of sodium or potassium humates.
Недостатком известного состава вл етс высока фильтраци в услови х высокой температуры.A disadvantage of the known composition is high filtration under high temperature conditions.
Цель изобретени - уменьшение фильтрации при сохранении флокулирующих свойств реагента.The purpose of the invention is to reduce filtration while maintaining the flocculating properties of the reagent.
Цель достигаетс тем, что компоненты реагента вз ты в следующем соотношении, мас.%:The goal is achieved by the fact that the components of the reagent are taken in the following ratio, wt.%:
Полиакрилонитрил0,3-4Polyacrylonitrile0,3-4
Щелочные гуматы натри Alkaline sodium humates
или кали Остальноеor Kali Else
Реагент дополнительно содержит лигносульфонаты или лесохимические смолы или терпеновый полимер при следующем соотношении компонентов, мас.%:The reagent additionally contains lignosulfonates or wood-chemical resins or terpene polymer in the following ratio, wt.%:
Полиакрилонитрил0,3-4,9Polyacrylonitrile0,3-4,9
Лигносульфонаты илиLignosulfonates or
лесохимические смолыwood chemical resins
или терпеновый полимер0,5-5or terpene polymer 0,5-5
Щелочные гуматы натри Alkaline sodium humates
или кали Остальноеor Kali Else
Изобретение иллюстрируетс следующими примерами.The invention is illustrated by the following examples.
Пример 1. В емкость загружают 0,3% полиакрилонитрила или побочных продуктов промышленности, содержащих полиакрилонитрил и 99,7% щелочных гуматов натри или кали . Затем ведут гидролиз полиакрилонитрила при температуре 85- 100°С до получени однородного раствора.Example 1. 0.3% polyacrylonitrile or by-products of industry containing polyacrylonitrile and 99.7% alkaline sodium or potassium humates are loaded into a container. Then polyacrylonitrile is hydrolyzed at a temperature of 85-100 ° C until a homogeneous solution is obtained.
Остальные примеры получени состава в соответствии с изобретением и результатов его испытани в сравнении с известным представлены в таблице.Other examples of the preparation of the composition in accordance with the invention and the results of its testing in comparison with the known are presented in the table.
