(2)石油天然气井位多处于中国西部这样交通不便的山区，巨额的运费使导致钻井成本进一步增加；(2) Oil and gas wells are mostly located in mountainous areas with inconvenient transportation like western China, and the huge freight costs further increase the drilling cost;
(3)柴油机和柴油发电机的噪音及污染物排放严重超标，影像了井位附近居民的生产生活，破坏环境；(3) The noise and pollutant emissions of diesel engines and diesel generators seriously exceed the standard, which affects the production and life of residents near the well site and damages the environment;
(4)柴油机及柴油发电机的维护成本高；(4) The maintenance cost of diesel engine and diesel generator is high;
(5)柴油机及柴油发电机的能源利用率明显低于电厂大型发电机组的能源利用率。(5) The energy utilization rate of diesel engines and diesel generators is significantly lower than that of large generator sets in power plants.
