而且可以大大意外事故损失，其主要功能有：●及时性。油田后方能够实时每个区域、甚至每口油、气井的生产动态，为快速制定生产和经营方案提供决策依据。●自动。在出现意外情况，如输油管线破裂，造成主管流量和分支管线流量之和产生较大差异，计算机经运算发出，提醒用户及时采取措施，事故损失。●在局部区域，如一个采油站或联合站内，出现异常情况，如某管线压力严重下降，可自动关闭相关阀门，防止事故发生。●统计数据的准确性。本提供各种形式的自动报表，不但节约大量人力，也了因人为因素造成的误差。●量小。由于采用了无线通讯技术，野外没有通讯线路，可大大量。●在采油站、联合站也可监控每口井或每个采油站的生产情况。 3、压力使用，在实际需要的压力段运行，据统计每下降1公斤压力可节能大约7%的能耗。
