Description
Изобретение относитс к нефтегазодобывающей промышленности, в частности к составам креплени призабойной зоны скважины.The invention relates to the oil and gas industry, in particular to the compositions of the wellbore bottomhole zone.
Известен состав дл креплени призабойной зоны скважины, содержащий фенолформальдегидную смолу и отвердитель 1 .A known composition for securing the well bottom zone contains phenol-formaldehyde resin and hardener 1.
Недостатком этого состава вл етс то, что он характеризуетс высокой коррозионной активностью.The disadvantage of this composition is that it is characterized by high corrosivity.
Наиболее близким к предлагаемому техническому решению вл етс состав дл креплени слабосцементированного продуктивного пласта, содержащий фенолформальдегидную смолу, воду и отвердитель - сол нокислый анимен 2.Closest to the proposed technical solution is a composition for attaching a weakly cemented productive formation, containing phenol-formaldehyde resin, water, and a hardener — hydrochloride animene 2.
Недостатком известного состава вл етс то, что его применение не обеспечивает сохранени проницаемости призабойной зоны продуктивного пласта.A disadvantage of the known composition is that its use does not ensure the preservation of the permeability of the bottomhole zone of the reservoir.
Целью изобретени вл етс получение состава дл креплени слабосцементированного продуктивного пласта, применение которого обеспечивает сохранение призабойной зоны продуктивного пласта.The aim of the invention is to obtain a composition for attaching a weakly cemented productive formation, the use of which ensures the preservation of the bottomhole zone of the productive formation.
Эта цель достигаетс тем, что состав , содержащий фенолформальдегидную , или мочевиноформальдегидную смолы , воду и отвердитель, содержит в качестве отвердител сол нокислый гидроксиламин при следующем соотно-. шении компонентов, вес.%: Фенолформальдегидна This goal is achieved by the fact that a composition containing a phenol-formaldehyde resin, or a urea-formaldehyde resin, water and a hardener, contains hydroxylamine hydrochloride as a hardener in the following ratio. Component weight, wt.%: Phenol formaldehyde
в 45-55 смола или мочевиноформальдегидна смола Сол нокислый гидрок10 силамин0 03-0,Ь ВодаОстальное Предлагаемый состав готов т следующим образом.45-55 resin or urea formaldehyde resin. Hydroxide 10 hydroxylmine 0 03-0, Ь Water Remaining The proposed composition is prepared as follows.

Изобретение провер лось в лабораторных услови х и сравнивалось с известным составом.The invention was tested under laboratory conditions and compared with a known formulation.
Основные результаты проведенных сравнительных испытаний приведены в The main results of the comparative tests are given in
30 таблице.30 table.
П йведенные данные свидетельствуют о тан, что применение предлагаемого состава, содержащего в качестве отвердител сол нокислый гидроксил- амин,обеспечит по Сравнению с известным повышение проница:ёмости призабойной зоны слабосцементированного продуктивного пласта до двух раз. The data indicate that the use of the proposed composition, containing hydroxyl amine hydrochloride amine as a hardener, will provide, in comparison with the known increase in permeability: the capacity of the bottomhole zone of the weakly cemented reservoir is up to two times.
Крепление призабойной зоны скважины предлагаемым составом осуществл етс по известной технологии.The mounting of the well bottom-hole zone by the proposed composition is carried out according to a known technology.
Сохранение более высокой проницаемости укрепл емой зоны обеспечивает, в свою очередь, повышение дебита продуктивного пласта в 2-3 раза, за счет чего ориентировочный экономический эффект от внедрени изобретени составит 3,7-6,2 тыс. руб на сквс1жину операщио.The preservation of higher permeability of the reinforced zone, in turn, increases the flow rate of the productive formation by 2-3 times, due to which the approximate economic effect from the implementation of the invention will be 3.7-6.2 thousand rubles per squire.
