How important is the gas production wellhead device to the development of gas production?

With the rapid development of my country's economy, the demand for natural gas continues to increase, the upgrading of related technologies and equipment is very fast, and the speed of industrial upgrading is very fast. In the actual drilling and mining process, the pressure on the wellhead is often very high. Improper operation can easily cause the wellhead equipment to be eroded and cause great harm to the surrounding environment. For this reason, the exploration and analysis of gas production wellhead equipment hopes to promote the development of my country's gas production industry, which can be beneficial effect.

The gas production wellhead device is mainly composed of three parts: casing head, tubing head and oil (gas) tree. The casing head is mainly used to connect each layer of casing and oil layer casing, and seal the annulus between the two layers of casing. The tubing head is mainly used to suspend the tubing running into the well and seal the annular space between tubing and casing. The Christmas tree is mainly used for opening and closing wells, adjusting pressure and output during production, testing with pressure gauges, measuring pressure at wellheads, and small-scale fishing operations.
