What are the components of the gas production wellhead? What is the role of each part?
The gas production wellhead device is mainly composed of casing head, tubing head and Christmas tree. The casing head is mainly used to connect each layer of casing to the oil layer casing and seal the annulus between the two layers of casing. The tubing head is mainly used to suspend the lower tubing and seal the annular space between the tubing and casing. Gas production wellhead devices are mainly used for operations such as opening and closing wells, adjusting pressure and production during production, testing with gauge pressure, measuring wellhead pressure, and small fishing.
Gas production wellhead device, including casing flange, tubing head and Christmas tree; the gas production wellhead device is characterized in that there are manual combined valves on the left and right sides of the tubing head and the left and right lower sides of the Christmas tree cross, which need to be installed in series. Flat valve: The valve body of the manual flat valve above the Christmas tree spool is integrated with the Christmas tree spool to form a four-way flat valve assembly.
For the conjoined valve and the four-way flat valve, you can choose the hidden stem flat valve or the open stem flat valve as the combined object; in addition to the valve body and stem, other similar parts of the flat valve are shared with each other. Therefore, on the basis of keeping the original function of the gas production wellhead device unchanged, the space size of the gas production wellhead device is greatly reduced, raw materials and installation time are saved, and the links that may cause high pressure leakage are reduced, which is more beneficial to oil workers. On-site operations; to achieve the purpose of reducing consumption and increasing efficiency.
