RockySea Onshore Thermal Recovery Wellhead


RockySea Petro has more than 40 years of experience in oil and gas wellhead & x-mas tree and valve production, with advanced manufacturing and testing equipment, can produce a variety of pressure levels, material levels, specification levels of well control equipment. After more than 20 years of development, Various types of thermal recovery wellhead & x-mas tree equipment have been formed, used in many oilfields in the world. RockySea Petro’s thermal recovery wellhead & x-mas tree are mainly of the following types:

  • Geothermal wellhead & x-mas tree
  • Blowout preventer Steam Injection and Oil Recovery Integration wellhead & x-mas tree
  • Steam injection and oil recovery dual tubing wellhead & x-mas tree
  • Single column dual-well thermal recovery wellhead & x-mas tree
  • Onshore thermal recovery oil and gas wellhead & x-mas tree
  • Conventional Steam injection and oil recovery wellhead & x-mas tree

Description 

Offshore thermal recovery wellhead & x-mas tree is designed by RockySea Petro according to CNOOC’s offshore operating conditions and thermal production process requirements. Offshore oil production platforms use offshore thermal recovery wellheads and Christmas trees, which require higher safety and tightness, and higher requirements for the configuration of wellheads and Christmas trees. thermal recovery wellhead & x-mas tree can be used to steam injection, well soaking, oil recovery.

It is consisted of three main parts including casing head, tubing head and X-mas tree. Thermal production wellhead and Christmas tree are composed of casing head, tubing head and Christmas tree, which can be used for steam injection, well soaking, oil recovery. The one side of the X-mas tree is connected with steam injection flow. It is a steam entrance. The other side with an adjustable needle valve is connected with oil recovery flow. By this side, the crude oil is sent to the oil transportation line.

The side of the tubing head with two valves is used to make nitrogen gas injection to annular space so that can improve the efficiency of thermal recovery and balance formation pressure. The pressure parts of the thermal recovery wellhead & x-mas tree are forged, and the main bore is equipped with a pneumatic safety valve, which improves the safety of the wellhead & x-mas tree operation. The PR2 plate valve is provided on the side outlet of the tubing head for the safety and reliability of nitrogen injection. This thermal recovery wellhead & x-mas tree obtains the national patent.
