PROCESSING OF THE WELLHEAD OF THE CHRISTMAS TREE

This article examines the structure, function, and significance of the wellhead assembly of a fountain armature in the operation of oil and gas wells using the fountain method. Its proper functioning is essential for the safe, efficient, and environmentally friendly operation of the well. Therefore, certain safety measures must be observed, and necessary actions should be taken to protect the environment during the installation, operation, and maintenance of the wellhead assembly. The wellhead is located on the surface of the well between the casing and the drilling floor during drilling and production processes. Its main functions are to suspend and support the production tubing, seal the annular space between the production tubing and the protective casing, prevent fluid leakage from the wellhead, regulate and control well pressure, manage the flow of the produced fluid, and provide access for various well operations. The article highlights the key aspects to be considered and the essential functions required for selecting a wellhead. Additionally, the wellhead must withstand high pressures generated in the well and meet the requirements necessary to prevent erosion caused by the flow of oil, gas, water, sand, clay, and other abrasive particles. Due to the aggressiveness of the environment, the surface of the wellhead must be protected against rust and corrosion. For this purpose, special steel alloys or corrosion-resistant materials should be used. To minimize these risks and ensure the safe operation of the well, it is essential to select the right materials, conduct regular inspections, and carry out necessary repair work. Research on improving the design of the wellhead, which is a crucial component of the wellhead equipment in fountain production, is one of the key tasks to ensure the continuity of operations. The main aim of this article is to improve the reliability of the wellhead, prolong the interval between maintenance operations, and boost its wear resistance.To achieve this, innovative technological solutions have been studied and proposed to improve the performance of the wellhead, reduce maintenance work, and extend the technical service period.
