摘　　要：目前普遍采用活塞式压力计来进行井口压力监测工作,但是该仪表缺点较多,越来越不适应气田开发的需要,因此急需寻找一种能够替代的测压仪表。通过对普通压力表、数字式压力计、压力变送器、活塞式压力计、井口电子压力计等测压仪表在20口气井上录取的1000多个现场测压数据进行对比,分别对活塞式压力计与普通压力表、压力变送器;井口电子压力计与压力变送器;数字式压力计、活塞式压力计及压力变送器间的实测压力数据进行了分析、研究,以找到井口高准确度的最佳测压方式和测压仪表。At present,piston gauge is commonly used to monitor wellhead pressure. But,it's necessary to develop a new pressure meter to replace this gauge since the latter can not meet the demand from field development any more. In this study,more than 1000 pressure-metering data of 20 wells,which were measured from some pressure meters of conventional gauge,digital gauge,pressure transmitter,piston gauge,wellhead electronic gauge,are contrasted; and then,actual data measured from piston gauge and conventional gauge as well as pressure transmitter,from wellbore gauge and pressure transmitter,from digital gauge and piston gauge as well as pressure transmitter are analyzed; at last,an optimal pressure meter with high accuracy for wellhead may be found.
