Abstract
Способ ступенчатого изменения потока текучей среды в скважине использует множество клапанов в нисходящей скважине, которые имеют отверстия различных размеров в корпусах клапанов, так что поток текучей среды может быть изменен путем частичного закрытия одного или более клапанов. Способ может быть использован для испытания газовых скважин, так что задержки хранения в буровой скважине, вызываемые сжатием и/или расширением газа в эксплуатационном трубопроводе, являются минимальными.Международная заявка была опубликована вместе с отчетом о международном поиске.The stepwise change method of fluid flow in a well uses a plurality of valves in a downhole, which have openings of different sizes in the valve bodies, so that the flow of fluid can be changed by partially closing one or more valves. The method can be used to test gas wells, so that storage delays in a borehole caused by compression and / or expansion of gas in a production pipeline are minimal. The international application was published along with an international search report.
