Downhole Equipment Sets
Sets of downhole tools for equipping the vertical and deviated gas wells are employed for:
- isolation of beds and isolation of flow string and casing clearance from the exposure of downhole medium by means of the packer during gas well operation as well as while repair works and routine inspection;
- joining and isolation of casing clearance and tubing inner cavity by means of the circulating valve during well completion and operation;
- overlapping of tubing by means of the cutoff valve when the well flow rate increases beyond the specified value in the monitored or automatic mode of operation;
- buildup of excessive hydraulic pressure inside the tubing cavity by means of shearoff valve in order to manipulate the packer.
