Description
Изобретение относитс к добыче газа, а именно к способам обнаружени солей в газовых скважинах.The invention relates to the extraction of gas, and in particular to methods for detecting salts in gas wells.
Целью изобретени вл етс повышение достоверности обнаружени солей в скважине и расширение функциональных возможностей за счет обеспечени возможности определени места отложени солей.The aim of the invention is to increase the reliability of the detection of salts in the well and to expand the functionality by enabling the determination of the place of deposition of salts.
Способ осуществл ют следующим образом .The method is carried out as follows.
Главной причиной солеотложени в скважинах вл етс резкое недонасыще- ние газа влагой при переходе его из пласта в призабойную зону. Нецонасы- щенность газа влагой постепенно уменьшаетс вверх по стволу скважины. Точка, в которой она равна нулю, определ ет верхнюю границу зоны солеотложени .The main cause of scaling in wells is a sharp under-saturation of gas with moisture when it passes from the reservoir to the bottom zone. The non-saturation of gas with moisture gradually decreases up the wellbore. The point at which it is equal to zero defines the upper boundary of the scaling zone.
Определ ют содеожание влаги в 1 м3 газа на устье скважине, дл чего пропускают поток газа через сепаратор,The moisture content in 1 m3 of gas at the wellhead is determined, for which a gas flow is passed through the separator,
замер ют количество отсепарированной влаги, дебит газа и дел т первую величину на вторую. Замер ют температуру и давление в сепараторе, определ ют количество оставшейс в газо- оой фазе влаги и суммируют полученное значение с частным от делени . определ ют по стволу скважины температуру м давление. По полученным данным рассчитывают влагоемкость газа на различных глубинах, например, через каждые 100 м. Влагоемкость газа на забое сравнивают с влагосодержани- ем на устье. Если забойна влагоемкость превышает влагосодержание на устье, делают вывод о недонасыщеннос- ти в скважине влагой и, следовательно , о протекании процесса отложени в скважине.The amount of separated moisture, the gas flow rate are measured and the first value is divided by the second. The temperature and pressure in the separator are measured, the amount of moisture remaining in the gaseous phase is determined and the value obtained is summed up with the partial separation. The temperature and pressure are determined by the wellbore. According to the data obtained, the water capacity of the gas at different depths is calculated, for example, every 100 m. The water capacity of the gas at the bottom is compared with the moisture content at the mouth. If the bottomhole moisture capacity exceeds the moisture content at the wellhead, it is concluded that the well is undersaturated in the well with moisture and, therefore, the process of deposition in the well proceeds.
Затем сравнивают значени влаго- емкости газа по стволу работающей скважины со значением содержани влаги в 1 м3 на устье, наход т положениеThen, the values of the moisture capacity of the gas in the wellbore of the working well are compared with the moisture content of 1 m3 at the mouth, the position
