| 摘 要： | 普通底阀无防砂和定压开启功能，对出砂严重的井况常出现层窜、返砂等问题。研制的新型调压底阀具有启闭压力可调、依靠液力启闭、液力缓7中和定压开启功能，能够及时开启定压开启机构，完成反洗井作业，保证洗井效果，有效防止了关井后地层返吐造成的出砂现象，保证了分层注水质量。

| Abstract: | Usual foot-valve often present flowing from one stratum to another and returning sands, etc. for the well of returning sands seriously without sands prevention and opening in a constant. For the adjustable shut-open pressure, opening or shutting by hydraulic pressure, cushioning by hydraulic pressure and opening by constant pressure, our adjustable foot-valve in pressure can open in time so as to finish the work of reverse circulation washing well, and ensure a good effect, and prevent sands well since the well is shut. This ensures the quality of the stratified flow pouring water into. |
