Description
Дл определени истинного места утечки жидкости производитс полный подъем насосно-компрессорных труб из скважины, на что затрачиваетс большое количество времени.To determine the true fluid leakage location, the tubing is fully lifted from the well, which takes a lot of time.
Предлагаемый способ дает возможность определить истинное место утечки жидкости из насосно-компрессорных труб без подъема их из скважины путем создани давлени в колонне подн тием на тросе Сваба при герметичном устьи скважины, на котором установлены уплотнение дл троса и редукционный клапан дл выпуска жидкости.The proposed method makes it possible to determine the true location of the leakage of fluid from tubing without lifting it from the well by creating pressure in the column by lifting up on the Swab cable with hermetic wellhead, on which the seal for the cable and the pressure relief valve are installed to release the fluid.
Давление жидкости может быть регистрировано на ленте, перемещение которой св зано через редуктор с перемещением троса, а места утечек определены по скачкам давлени , записанным на ленте.Fluid pressure can be recorded on a tape, the movement of which is connected through a reducer with cable movement, and the locations of leaks are determined by the pressure jumps recorded on the tape.
На чертеже изображена принципиальна схема устройства дл осуществлени этого способа.The drawing shows a schematic diagram of an apparatus for implementing this method.
Сущность способа заключаетс в следующем.The essence of the method is as follows.
В колонну труб / на тросе опускают сваб 2 на всю длину подвески насосно-комэтрессорных труб, после чего заполн ют колонну жидкостью через заливочное отверстие 3 до усть скважины, устанавливают прибор , пропустИВ трос через сальвик 4, и герметизируют устье скважины. Подн тием сваба создают давление в трубах при герметичном устьи скважины, на котором установлен редукционный клапан 5 дл выпуска жидкости.Swab 2 is lowered into the pipe string / on the cable over the entire length of the suspension of the pumping-cometatory pipes, then the column is filled with liquid through the filling hole 3 to the wellhead, the instrument is installed, the cable is passed through salvik 4, and the wellhead is sealed. The rise of the swab creates pressure in the pipes with a sealed wellhead, on which the reducing valve 5 is installed to release the fluid.
Трос, на котором опущен сваб, соединен через отжимные ролики 6 и редуктор 7 с лентоцрот жным механизмом 8, который движетс в соответствии с движением троса, отража местоположение сваба на диаграмме 9.The cable on which the swab is lowered is connected via squeezing rollers 6 and a gearbox 7 to a lentocrot mechanism 8, which moves in accordance with the movement of the cable, reflecting the location of the swab in diagram 9.
№ 150455- 2 При прохождении сваба лсд местом утечки на диаграмме будет зафиксирован скачок давлени с помощью пера 10, соединенного с регистратором // утечки, которому передаетс давление, возникающее в трубах.No. 150455-2 When a swab passes through the leak, the diagram will record a pressure jump using a pen 10 connected to a leakage recorder, to which pressure occurring in the pipes is transferred.
