Description
(54) СПОСОБ ДОЗИРОВАНИЯ РЕАГЕНТА В СКВАЖИНУ(54) METHOD FOR DOSING THE REAGENT TO THE WELL
II
Изобретение относитс к нефтегазодобывающей промышленности, в частности к способам дозировани подачи в нефт ные и газовые скважины жидких химпродуктов с целью предотвращени коррозии оборудовани , отложени парафина и солей, образовани стойких эмульсий нефти и воды и т.д.The invention relates to the oil and gas industry, in particular to methods for metering the supply of liquid chemical products to oil and gas wells in order to prevent equipment corrosion, deposition of paraffin and salts, formation of stable emulsions of oil and water, etc.
Известен способ ввода реагента в скважину , включающий закачку реагента в насосно-компрессорные трубы 1.A known method of entering the reagent into the well, including the injection of reagent into the tubing 1.
Наиболее близким к- изобретению вл етс способ дозировани реагента в скважину, включающий закачку реагента в полость, образованную кольцевым надпакерным пространством между внутренней поверхностью обсадных труб и наружной поверхностью насосно-компрессорных труб, и дозированную подачу реагента через циркул ционный клапан в насосно-компрессорные трубы 2.The closest to the invention is a method of dispensing a reagent into a well, including pumping a reagent into a cavity formed by an annular nadpaknerny space between the inner surface of the casing and the outer surface of the tubing, and metering the reagent through a circulation valve into the tubing 2 .
Недостатком способа вл етс сложность управлени работы циркул ционного клапана.The disadvantage of the method is the difficulty of controlling the operation of the circulating valve.
Цель изобретени - упрощение осуществлени способа.The purpose of the invention is to simplify the implementation of the method.
Указанна цель достигаетс тем, что подачу ингибитора осуществл ют путем продавливани его в подпакерную полость незамерзающей жидкостью.This goal is achieved by supplying the inhibitor by pushing it into the sub-packer cavity with an antifreeze liquid.
На чертеже изображено устройство, реализующее способ, общий вид.The drawing shows a device that implements the method, General view.
В обсадной колонне 1 скважины уплотнена пакером 2 колонна насосно-компрессорных труб 3. Пакер имеет дроссельный клапан 4, настроенный таким образом, что перепад давлени дл его открыти больще In the casing string 1 of the well, the tubing string 3 is sealed with a packer 2. The packer has a throttle valve 4 configured so that the pressure drop to open it is more
to давлени столба жидкости реагента над пакером. В затрубном пространстве установлена трубка 5 малого диаметра, выведенна на поверхность и снабженна вентилем 6. Затрубное пространство через задвижку 7to reagent liquid column pressure over packer. A small-diameter tube 5 is installed in the annular space, brought to the surface and provided with a valve 6. The annulus through the valve 7
55 и трубопровод 8 соединено с дозатором 9, а дозатор - с резервуаром 10. Дозатор имеет байпасную линию с вентилем 11. Резервуар снабжен указателем уровн 12 и заполнен инертной жидкостью, не замерзающей при низких температурах и имеющей меньщую плотность, чем реагент, например чистой нефтью или дизельным топливом . Затрубное пространство скважины через трубку 5 заполнено реагентом.55 and the pipeline 8 is connected to the dispenser 9, and the dispenser is connected to the reservoir 10. The dispenser has a bypass line with the valve 11. The tank is equipped with a level indicator 12 and is filled with an inert liquid that does not freeze at low temperatures and has a lower density than the reagent, for example, pure oil or diesel fuel. The well annulus through tube 5 is filled with reagent.
