pressure surge

The principle of wellhead pressure pulsation technology is to pressurize the sealed annular with hydraulic pulse pressure,the annular cement slurry will then keep moving up and down due to the micro-compressibility of the fluid,and the cement bond quality can thus be improved.

井口脉冲加压是注完水泥后给密闭的环空施加水力脉冲压力,利用流体的微可压缩性使环空水泥浆处于上下往复活动状态来改善水泥浆凝固特性,达到提高水泥胶结质量的目的。

The basic reason is that the pulse pressure, produced by the pulse current, affects the nucleation and growth of the alloy.
