V-Packing is a combination seal with self-sealing principle, mainly used for sliding seal and long-lasting seal between bushings, which is divided into non-elastomeric seal assembly and elastomeric seal assembly according to material combination. YeHee Energy can provide airtight V-Packing in accordance with API 6A 21th U class PR2 standard. The materials of V-Packing meet the immersion requirements of API 6A 21th AppendixF.1.13. The maximum sealing performance of sliding V-Packing can reach 204℃, 105MPa.

The floating seal latch has no anchoring mechanism and is sealed with the inner diameter of the packer seal housing by the seal assembly to maintain the pressure integrity of the connected pipe string. Can be used for tieback production, can also be used as a compensation mechanism when the length of the string changes due to internal and external pressure or temperature changes; The addition of unique structures can also be used to run and set packers.

The AST setting tool can be used to run the string and set the packer. The tubing is connected to the setting tool to run the packer and tail pipe along with it. There are a shear-out ball seat and spare ball seat. The advantage of the tool is simplify the string. There are two release mechanisms. One is casing hydraulic release by apply pressure into the annulus, the other is mechanical release by apply right-hand rotation of the string.

DHTP Hydraulic Permanent packer is a permanent, milled completion packer designed for use in extreme environments such as high temperature and pressure. Ideal for single trip completion and injection wells. The DHTP-1 hydraulic permanent packer is based on the DHTP, which changes the upper tubing connection structure to a sealing bore; The packer can be connected to the anchor seal assembly, it was run with its liner pipe and upper production string; The packer can also be run and set with an accompanying setting tool. After setting is complete, the setting tool is removed and the production string can be run and tieback to begin construction.

DHL hydraulic set permanent packers specially designed for gas storage, can be used in extreme environments such as high temperature and high pressure. The packer can be connected to the anchor seal assembly, It was run with its liner pipe and upper production string at the same time, achieve a one-run string completion. The DHL hydraulic permanent packer is also available with an accompanying setting tool that runs the packer in conjunction with the liner it carries; The setting tool is provided with a shot-down ball seat and a spare, this approach simplify string tool configuration; Once the packer is set and the setting tool is removed, the production string can be run to tie back with the packer to begin construction.

The SFA packer is a kind of retainer production packer,can withstand a 10,000PSI upper and lower pressure differential. The hydraulic setting mode which is special designed for production, injection and zonal isolation. The SFA permanent packer with tail pipe run into well. After packer setting, take-off running tool string then run production string to construction. Yehee energy can provide the matched running tool,which can interchange with Baker 20# hydraulic setting too
