利用天然气压缩机气举采气和增压输气,是解决四川中晚期气田因井压下降造成采输困难的办法。由于气田工况变化对压缩机性能有所影响,因此必须通过对压缩机进行转速调节,余隙调节,单作用运行,换缸,更换机种等方式来适应压缩机的非额定工况。并指出,为了满足气田变工况的要求,必须解决好压缩机选型和正确使用问题。 Natural gas compressor gas lift gas and pressurized gas is to solve the middle and late gas fields in Sichuan due to downhole pressure caused by the difficulties of transportation. Due to the change of working conditions of the gas field, the performance of the compressor is affected. Therefore, it is necessary to adapt to the non-rated condition of the compressor by adjusting the speed of the compressor, adjusting the clearance, operating with a single action, changing the cylinder and changing models. And pointed out that in order to meet the requirements of gas field conditions, we must solve the compressor selection and the proper use of the problem.
