1、Introduction

Choke and Kill Manifold is necessary in well control process. The choke valves can be used for controling the casing pressure to stablize the well bottom pressure when drilling. And while the normal circum of mud was blocked, it is able to balance the inner pressure of ground by pushing mud through Kill Manifold by pump. Choke and Kill Manifold can also be used for well washing.
