Abstract

The present invention relates to a perforating device and a method of perforating using the same. The perforating device includes a perforator connected through the oil pipe, a bridge plug setting tool fixedly installed downstream of the perforator, and a bridge plug connected with the bridge plug setting tool through a first shear nail. The perforating device may also include a positioner. The perforating device of the present invention uses a bridge plug for plugging, and the plug surface is accurately controlled. In addition, this perforating device achieves perforation through hydraulic pressure, which improves the safety of construction.

Description

technical field [0001] The invention relates to an oil and gas well completion device, in particular to a perforation device. The invention also relates to a method of perforating using such a perforating device. Background technique [0002] In the completion process of oil and gas wells, in the oil and gas wells completed by perforation, the perforation holes are the only channel to communicate the production layer and the wellbore. For the appropriate reservoir, the use of appropriate perforation equipment can improve the perforation quality and minimize the damage to the reservoir. [0003] At present, the coiled tubing staged fracturing methods commonly used in oil and gas wells mainly include fracturing after layered hydraulic sandblasting and perforating, and coiled tubing with a straddle packer for sealing fracturing. When using hydraulic sand blasting perforation, after the perforation and fracturing of a design layer are completed, it is necessary to fill the wel...
