The operation steps of oil wellhead device vary depending on the specific equipment, production conditions and operation requirements. But generally speaking, the operation of oil wellhead device can be summarized into the following basic steps:
1. Preparation stage
Wearing labor protection supplies: The Christmas tree manufacturer ensures that the operator wears labor protection supplies correctly, such as safety helmets, work clothes, protective glasses, protective gloves, etc., to ensure safe operation.
Inspect equipment: Conduct multi-faceted inspections on the wellhead device, including the integrity, sealing and flexibility of components such as Christmas trees, valves, tubing heads, and casing heads. Ensure that all components are not damaged, leak-free, and in good working condition.
Prepare tools: Prepare the tools and utensils required for operation, such as wrenches, screwdrivers, pipe clamps, pressure gauges, record books, etc.
2. Opening stage
Confirm the process: Confirm that the production process of the oil well has been established, including that the tubing, casing, ground process pipelines, etc. have been connected and are unobstructed.
Open the valve: According to the operating procedures and the design requirements of the wellhead device, gradually open the valve on the wellhead device. Generally, the production valve is opened first, and then other auxiliary valves, such as test valves and sewage valves, are opened. When opening the valve, it should be done slowly to avoid equipment damage or safety accidents caused by sudden pressure increase.
Monitor pressure: After opening the valve, use monitoring tools such as pressure gauges to monitor the wellhead pressure in real time to ensure that the pressure fluctuates within the normal range. If abnormal pressure is found, the cause should be found out in time and measures should be taken to deal with it.
3. Production stage
Adjust flow: According to production needs, the liquid production and gas production of the oil well are controlled by adjusting the valves on the oil tree. When adjusting, the operating procedures and safety production requirements should be followed to avoid equipment damage or safety accidents caused by operating errors.
Inspection equipment: Regularly inspect the wellhead device to check the operation, sealing and flexibility of each component. If any abnormal situation is found, it should be handled in time and the relevant data should be recorded.
Record data: Relevant data such as wellhead pressure, liquid production, gas production, etc. should be recorded during the production process. These data are of great significance for analyzing the production status of oil wells and formulating production plans.
IV. Closing stage
Close the valve: When the oil well needs to be shut down or maintained, the valves on the wellhead device should be gradually closed according to the operating procedures. Generally, the production valve should be closed first, and then other auxiliary valves. When closing the valve, it should be done slowly to avoid sudden increase or decrease in pressure causing equipment damage or safety accidents.
Clean up the site: After closing the valve, the wellhead device should be cleaned and maintained. When cleaning the site, make sure that no debris is left and restore the equipment to its original state; when maintaining and maintaining, follow the operating procedures and equipment requirements to ensure that the equipment is in good condition for the next use.
V. Precautions
Comply with the operating procedures: During the operation, strictly abide by the operating procedures and safety production requirements to ensure correct operation.
Pay attention to safety protection: During the operation, pay attention to safety protection measures to ensure the personal safety of the operator.
Record data in time: During the production process, relevant data should be recorded in time for subsequent analysis and processing.
Inspect equipment regularly: Regularly inspect and maintain the wellhead device to ensure that the equipment is in good condition.
Please note that the above operation steps are only general descriptions. The specific operation may vary depending on the equipment model, production conditions and operating requirements. In actual operation, adjustments and improvements should be made according to specific circumstances.
