[0010] Such as figure 1 , figure 2 As shown, a fracturing gas production wellhead device includes a tubing head assembly 1; also includes a fracturing device and a gas production device. The fracturing device includes a main valve I2 that can be connected to the upper end of the tubing head assembly 1, connected to the main Main valve II3 at the upper end of valve I2, and fracturing tree 4 connected to the upper end of main valve II3;
[0011] In fracturing conditions, a fracturing device is installed on the tubing head assembly 1. The fracturing device is not connected to the suspension flange and jack wire, which greatly improves the reliability of the fracturing channel sealing, completely eliminates the hidden danger of jack wire leakage, and improves Operating efficiency and service life of top wire seals.
[0012] The gas production device includes a main valve I2 that can be connected to the upper end of the tubing head assembly 1, a suspension flange 5 connected to the up...
