注水井因周边新钻井、修井等原因需放压降低井底压力,水井放压是油田开发过程中的一个常见作业。注水压力通常较高,因此,水井放压时间往往较长。注水井井口安装有单向阀,为避开单向阀的影响,使得目前常用的几种放压方式均存在作业程序比较复杂、作业风险高、费用高等问题。可调水嘴水井放压短节是在原有井口单向阀的基础上,设计加工了可调换水嘴的单向阀阀芯,通过更换阀芯,即可解决放压污水无法通过 Water injection wells due to the surrounding new drilling, workover and other reasons to reduce the pressure to reduce the bottom hole pressure, well pressure relief oilfield development process is a common operation. Water injection pressure is usually higher, therefore, the well pressure relief pressure tends to be longer. In order to avoid the influence of the one-way valve, there are several commonly used methods for pressure relief such as complicated operation procedure, high operation risk and high cost. Adjustable spout wells pressure relief spur is in the original wellhead one-way valve based on the design and processing of the one-way valve can be changed tap, by replacing the spool, you can solve the pressure drop sewage can not pass
