Failure Analysis and Treatment of Natural Gas Regulator Skid
With the development of overseas oilfield blocks,petroleum enterprises have invested in the construction of gas turbine power stations to convert the associated gas into electric energy for oil-field production.Because the planned natural gas processing plant has not been built,the associated gas processing device is not perfect,the associated gas contains many impurities,the pressure failure of nat-ural gas regulator skid often occurs,which directly affects the safe operation of gas turbines.Through the analysis of the structure of natural gas regulator skid and the principle of the regulator valve from two different manufacturers,a modification scheme of using oilfield associated gas regulating skid,and the correction method of assembly error of the pilot valve provided by the manufacturer are put forward re-spectively,which can ensure natural gas regulator skid to regulate gas pressure quickly and steadily for the gas turbine in acceleration control,primary frequency control,island mode and so on.It provides technical support for increasing and stabilizing crude oil production in overseas oilfield blocks.
