Description
Изобретение относитс к области изучени фильтрационных свойств горных нород в нолевых услови х.The invention relates to the field of studying the filtration properties of mountainous gases under zero conditions.
Известны способы гидрогеологических откачек жидкости из малодебитных скважин, заключающиес в том, что в скважину устанавливают перфорированную колонну труб с отверсти ми на отметках динамического уровн .There are known methods for hydrogeological pumping of liquid from low-yield wells, which consist in installing a perforated string of pipes with openings at dynamic level levels into a well.
Предлагаемый способ отличаетс тем, что в колонну ииже перфорационных отверстий устанавливают мерный сосуд, фиксируют момент его заиолнени , и извлекают сосуд на поверхность.The proposed method is characterized in that a measuring vessel is installed in the column and below the perforations, the moment of filling is fixed, and the vessel is removed onto the surface.
Это позвол ет повысить точность измерени дебита.This makes it possible to increase the accuracy of the flow rate measurement.
Предлагаемый способ по сн етс чертежом.The proposed method is illustrated in the drawing.
В скважииу / опускают колонну труб 2, нижнее отверстие которых закрывают водонепроницаемой заглушкой 3. Трубы устанавливают таким образом, чтобы отверсти 4 раснолагались на отметках динамического уровн 5.In the well, the column of pipes 2 is lowered, the lower opening of which is closed by a waterproof plug 3. The pipes are installed in such a way that the openings 4 are located at elevations of the dynamic level 5.
Мерный сосуд 6 опускают в скважину на каротажном кабеле 7 так, чтобы верхний край его был ниже отверстий колонны.Measuring vessel 6 is lowered into the well on the logging cable 7 so that its upper edge is below the holes of the column.
Перед началом опыта прп помон ц мерного сосуда воду из скважины откачпвают до динамического уровн . Вода из скважины стекает через отверсти неиосредственно в. мерный сосуд, в верхней части которого закрепл ют датчик электроуровиемера 8, которым определ ют момент заполнеии сосуда водой. Датчик соединен с сигнальным фибором 9, указывающим момент заиолнени мерного сосуда .Before the start of the experiment, the well water is pumped out to the dynamic level. Water from the well flows through the holes directly in. a measuring vessel, in the upper part of which a sensor of electrical leveling device 8 is fixed, by which the moment of filling the vessel with water is determined. The sensor is connected to the signal fiber 9, indicating the moment of filling the measuring vessel.
После заполнени сосуд извлекают на поверхность , удал ют воду и снова опускают в скважину.After filling, the vessel is removed to the surface, the water is removed, and again lowered into the well.
Предмет изобретенн The subject invented
Способ опытпых гидрогеологических откачек жидкости из малодебптных скважин путем установки в скважнну перфорированной колонны труб с отверсти ми на отметках дииамического уровн , отличающийс тем, что, с целью повыщени точности намерени , дебита, в колонну ниже перфорационных отверстий устанавливают мерный сосуд, фиксируют момент его за полпенни и извлекают сосуд на поверхность.Hydrogeological method of pumping out fluid from low-depletion wells by installing perforated pipes into the wellbore with holes at the diaamic level marks, characterized in that, in order to increase the accuracy of the flow rate, a measuring vessel is installed in the column below the perforation holes and remove the vessel to the surface.
