DEVICE FOR INSTALLATION OF PROFILE PACKER IN WELL

摘要

FIELD: oil and gas industry.SUBSTANCE: device includes a body with the upper and lower subs, guiders at the external surface expanded bottom-up by mandrel inserts capable to limit a longitudinal movement by means of pushers along the guiders, and a cylinder with an annular piston placed below and interacting with the pushers and capable of an upward movement limitation at the calibrated load due to the adjuster. The cylinder actuator is connected rigidly to the lower sub; the body is equipped with a thrust from the outside. The adjuster is made as a spring installed between the body thrust and the annular piston before it is pressed downwards.EFFECT: improved quality and maintainability of the profile packer installation, and reduced accident rate.1 dwg
