　　　　I have been working at the oil production facility for 39 years, serving as the supervisor in charge of oil production engineering and on-site construction at the oil field. It refers to the process management for a single well (including mechanical oil extraction), from the metering station to the main pipeline, then to the transfer station, the initial processing station, and finally to the export of crude oil. As of now, after more than 30 years, it is still the same. In 1976, a pilot project for automation was carried out in one block, which involved eliminating metering stations and using automated single-well metering at transfer stations. I was the supervisor at the oil production plant, but the project was not successful. It’s not all due to technical factors; there are issues with the automated instruments as well. There are also mechanical reasons related to the multi-way valves, as well as cases of vandalism by local people, etc. At present, oil production plants still operate largely following a process that involves individual wells, metering stations, and transfer stations. The above is provided for the original poster’s reference.

Thanks for the advice. We are currently carrying out a pilot project to simplify the pipeline transportation process. It hasn’t been put into operation yet, so I don’t know how it will perform

The oil and gas gathering and transportation in gas fields may differ from that in oil fields. In the gas field where I work, there are three scenarios: first, direct measurement at individual wells, followed by transportation through dedicated pipelines from those wells to main lines and then to processing plants； Secondly, it is through a single well, via a single-well transfer pipeline to a valve bank, then to the main pipeline, and finally to the treatment plant for metering (at a level-1.5 distribution station) ； Third, from a single well, the fluid is transported via a dedicated pipeline to a metering station (or gas collection station) for measurement, and then sent through main pipelines to a processing plant (in a secondary distribution network). Currently, there are very few natural gas production facilities with a three-stage distribution system.

For the oil well metering in some areas of our facility, we have tried the indicator diagram method (which involves converting data on dynamic production at the wellhead; there are ready-made software programs available for this purpose). ), the metering stations were removed, which was quite successful, but this approach is suitable for oilfields with relatively low oil and gas levels.

We are currently conducting a pilot project to simplify the oil transportation process by eliminating metering stations and trying out a wellhead metering method based on power diagrams. The effectiveness remains to be tested

May I ask, can wells with a slightly higher oil-to-gas ratio have their flow rates measured using correction factors in the work diagram method?

Good topic. Here, we adopt unified collection and transportation to central well stations, with metering at individual wells

The simplified fluid transfer process we have in place has proven to be effective once it was put into operation; the backpressure at the wellheads has decreased compared to before, and the booster pumps at the metering stations have been removed
