Choke manifolds
Introduction
Choke manifolds are used for choking the drilling fluid which is returned from the well. Adjust the choke valve can change throttling degree. Increasing throttling, can make bottom pressure of the well higher than ground pressure, avoid ground liquid flowing into the well immoderately, carry out well-kill operation. Reducing throttling to non- throttling can realize soft closing of the well which can protect the wellhead.
