气井在投产时一般要采用降液面负压射孔工艺,通过对目前降液面方法存在问题分析,有针对性地 开发了降液器,并介绍了产品的结构和主要技术特点,在实际应用中,取得了良好的效果,彻底解决了降液面时遇 到的协调多、工期长、工序杂、成本高、不安全、效果不稳定的问题,有一定的推广价值。 When the gas well is put into operation, it is generally required to use the negative pressure drop perforation process of the liquid surface. Based on the analysis of the problems existing in the current descending liquid surface method, the downcomer is developed in a targeted manner and the structure and main technical features of the product are introduced. Application, and achieved good results, completely solve the falling surface encountered more coordination, long duration, complex processes, high cost, unsafe, the effect is not stable, there is a certain value of the promotion.
