Description
в пределах, рекомендованных дл данной скважины, затем с помощью лебедки плавно открывают циркул ционный клапан 1 и, манипулиру им, по расходомеру 6 устанавливают заданный режим ингибировани .within the limits recommended for this well, then with the help of a winch, the circulation valve 1 is opened smoothly and, by manipulation, a predetermined inhibition mode is established by the flow meter 6.
При открытом циркул ционном клапане 1 ингибитор из пространства между лифтовой и эксплуатационной колоннами перетекает в лифтовую колонну 2 и увлекаетс потоком добываемого газа в сепаратор 4. Отсепарированный ингибитор поступает в дроссель-дегазатор 7 дл выделени растворенного в нем газа. Дегазированный ингибитор направл етс в емкость 5, а затем через расходомер 6 поступает в межтрубное пространство.With the circulation valve 1 open, the inhibitor flows from the space between the lift and production columns into the lift column 2 and is entrained in the flow of produced gas to the separator 4. The separated inhibitor enters the choke-degasser 7 to release the gas dissolved in it. The degassed inhibitor is sent to the tank 5, and then through the flow meter 6 enters the annular space.
Газ дегазации подвергают дополнительной сепарации и далее направл ют в утилизационную систему.Gas degassing is subjected to additional separation and then sent to the utilization system.
В случае, когда вместе с газом добываетс значительное количество углеводородного конденсата, который легче ингибитора, его вместе с газом отвод т из дроссель-дегазатора в утилизационную систему.In the case when a significant amount of hydrocarbon condensate, which is lighter than the inhibitor, is extracted with the gas, it together with the gas is withdrawn from the choke-degasser to the utilization system.
Если вместе с газом из скважины поступает вода, котора раствор етс в ингибиторе, то дл поддержани заданной концентрации ингибитора в межтрубном пространстве часть отработанного ингибитора вместе с газом удал ют из дроссель-дегазатора, а в емкость подкачивают нужное количество свежего ингибитора .If water that dissolves in the inhibitor comes along with the gas from the well, then to maintain the desired concentration of inhibitor in the annulus, part of the spent inhibitor is removed from the choke-degasser with gas and the right amount of fresh inhibitor is pumped into the tank.
Благодар использованию устройства дл ингибировани скважины невозможен прорыв газа в кольцевом пространстве, а следовательно , коррози эксплуатационной колонны, так как осуществл етс контроль уровн ингибитора в межтрубном пространстве. Кроме того, устройство позвол ет существенно сократить расход ингибитора.Due to the use of a device for inhibiting a well, gas breakthrough in the annular space and, consequently, corrosion of the production string, is impossible, since the level of the inhibitor in the annular space is monitored. In addition, the device can significantly reduce the consumption of the inhibitor.
