So‘nggi yillarda dunyоda qаzib оlinishi qiyin bо‘lgan gaz zaxiralari
soni ortmoqda. Shu bilan birga, mаhsuldоr quduqlаrning suvlаnishi va murаkkab
shаrоitlarda ularni samarali ishlаtish masalalari tobora dolzarb bo‘lib bormoqda.
Gaz va gazkоndensat quduqlаrining suvlanishi ularni qаzib chiqаrish jarаyоnida
jiddiy muammоlarni yuzaga keltiradi. Gaz va gazkondensat konlarida quduqlarni
ishlatishning yakuniy bosqichida qatlam bosimi va oqim tezligining pasayishi
natijasida quduqlar tubida suyuqlik to‘planishi sodir bo‘ladi. Bu esa bosim
yo‘qotishlarining ortishi, quduqlar debitining kamayishi va uglevodorodlarning
komponent bera oluvchanligining pasayishiga olib keladi. Bugungi kunda
ushbu muammoni bartaraf etish uchun produvkа usulidаn foydаlanilmоqda.
Gazning bevosita atmosferaga chiqarilishi orqali amalga oshiriladigan ushbu
usul gaz yo‘qotilishiga sabab bo‘ladi, bu esa atrof-muhit va quduqning yaqin
zonalariga salbiy ta’sir ko‘rsatadi. Ushbu maqolada O‘zbekiston Respublikasi gaz
va gazkondensat konlarida quduq tubida yig‘ilgan suyuqliklarni yer yuzasiga
chiqarish uchun qo‘llangan produvka usuli, shuningdek, gaz va gazkondensat
konlari quduqlarining o‘z-o‘zidan tiqilishi natijasida yo‘qotilayotgan tabiiy gaz
miqdori tahlil qilingan.

В последние годы в мире увеличивается количество
трудноизвлекаемых запасов газа. Одновременно всё более актуальными
становятся вопросы обводнения и эффективной эксплуатации в сложных
условиях продуктивных скважин. Обводнение газовых и газоконденсатных
скважин вызывает серьёзные проблемы в процессе их эксплуатации.
На заключительном этапе разработки газовых и газоконденсатных
месторождений вследствие снижения пластового давления и скорости
притока происходит накопление жидкости в призабойной зоне скважин.
Это, в свою очередь, приводит к увеличению потерь давления, снижению
дебита скважин и уменьшению способности пласта отдавать
углеводородные компоненты. В настоящее время для устранения данной
проблемы используется метод продувки. Этот метод, основанный на
непосредственном выбросе газа в атмосферу, приводит к потерям газа,
что оказывает негативное воздействие на окружающую среду и зоны,
прилегающие к скважине. В статье проанализирован метод продувки,
применяемый для удаления жидкости, скопившейся на забое скважин
газовых и газоконденсатных месторождений Республики Узбекистан,
а также объёмы потерь природного газа, происходящих вследствие
самопроизвольного закрытия скважин.
Recently, the number of hard-to-recover gas reserves has been
increasing worldwide. At the same time, issues related to water encroachment
and the efficient operation of productive wells under complex conditions have
become increasingly relevant. Water influx in gas and gas condensate wells causes
serious operational challenges. In the final stages of development of gas and gas
condensate fields, due to declining in reservoir pressure and inflow rates, fluid
accumulates in the bottomhole zone of wells. This, in turn, leads to increased
pressure loss, reduced well flow rates, and decreased reservoir capacity to yield
hydrocarbon components. Currently, the blowdown method is used to address
this issue. This method, based on the direct release of gas into the atmosphere,
results in gas losses and has a negative impact on the environment and areas
surrounding the well. This article analyzes the blowdown method used to remove
fluid accumulation from the bottom of gas and gas condensate wells in the
Republic of Uzbekistan, as well as the volume of natural gas losses resulting from
the spontaneous shutdown of wells.
