Claims (1)

Способ исследования на герметичность эксплуатационной колонны нагнетательной скважины, включающий спуск в скважину пакера на кабель-канате, приводящегося в рабочее положение с помощью электрического двигателя, перекрытие ствола скважины пакером, создание давления над пакером путем нагнетания жидкости в скважину и регистрацию изменения давления устьевым манометром, по которому судят о негерметичности эксплуатационной колонны, отличающийся тем, что регистрацию изменения давления осуществляют одновременно и под пакером с помощью аналогичного манометра, что и на устье, спускаемого вместе с пакером через трубное пространство насосно-компрессорных труб, при этом при соответствии изменений показателей обоих манометров судят о негерметичности пакера, а в случае изменения показателя манометра на устье при постоянстве показания манометра под пакером делают заключение о негерметичности эксплуатационной колонны.A method for testing the tightness of the production casing of an injection well, which includes lowering the packer into the well on a cable-rope driven by an electric motor, shutting off the wellbore with a packer, creating pressure above the packer by injecting fluid into the well and recording pressure changes with the wellhead pressure gauge, which is judged on the leakage of the production string, characterized in that the registration of pressure changes is carried out simultaneously and under the packer with the help of logical pressure gauge, as on the mouth, which is lowered together with the packer through the tubing space of the tubing, in case of changes in the indicators of both gauges, the packer is leaking, and if the pressure gauge on the mouth changes when the pressure gauge under the packer is constant, leaky production casing.
