AI Technical Summary

Technical Problem

Traditional offshore oil and gas platform wellhead hydraulic output testing lags behind offshore commissioning, making it impossible to accurately monitor system performance parameters on land, resulting in high risks, high costs, and delays in production during offshore commissioning.

Method used

A method for testing the functionality of wellhead panels on offshore oil and gas platforms is designed. A portable simulator is used to simulate the hydraulic demand of the Christmas tree valves during the onshore commissioning phase, and to verify whether the hydraulic output of the wellhead panel meets the action requirements of the Christmas tree valves. The method includes simulator assembly, hydraulic system preprocessing, wellhead panel hydraulic interface connection, hydraulic output verification, and response speed testing.

Benefits of technology

This enables early elimination of hydraulic faults in the wellhead pan during the onshore commissioning phase, reducing the workload and risks of offshore commissioning, shortening the production cycle, reducing costs, and improving testing accuracy and efficiency.
