In the process of perforation and fracturing of horizontal wells, the main function of the cable pressure control equipment is that the fracturing vehicle hydraulic pressure pumps the perforating gun and the bridge plug hydraulic into the downhole level pre-calculated position. In the process of perforation and fracturing of horizontal wells, the main function of the cable pressure control equipment is that the hydraulic pressure of the fracturing vehicle is pumped into the pre-calculated position of the horizontal section of the downhole and the plug is not blown, And after the completion of a period of time, replace the gun and shoot, under pressure again run in a new horizontal section, in such continuous perforation, but do not blow off the circulation process, dynamic and static to seal the wellhead, control the wellhead pressure, Provides pressure buffers and transition zones for bridge plug and perforating gun strings. At the same time, during the operation of the wellhead ac...
