It can provide injection and production integrated wellhead device, self-supporting cut-off valve, control system and other products for gas storage well sites.

Solution technical introduction

As the proportion of natural gas in China's primary energy consumption continues to rise, in order to ensure the smooth operation of natural gas supply, China's gas storage construction has entered a period of great development. However, at the same time, the construction of gas storage in China is still facing many difficulties, such as deeper and deeper burial, worse and worse reservoir conditions, more fractured structure, more complex fluid components, and more difficult reservoir and water reservoir construction. On-site devices need to solve the integrated working conditions of natural gas injection for gas storage and meet the production and operation functions. Through the variable casing head structure, relying on the top wire to push the support block to form the bearing step, part of the wellhead adopts metal seal slip hanger, the overall performance reaches the advanced level in foreign countries.
