Abstract
Official abstract text for this publication.
Diverting flow in a drilling fluid circulation system to regulate drilling fluid pressure. A pump of a drilling fluid pressure regulation system for a well bore can discharge drilling fluid through discharge piping at flow rate. A pressure control device has an inlet connected to the discharge piping and an outlet connected to bypass piping. A processor connected to the pump and the pressure control device can adjust the pressure control device to modify a pressure of the drilling fluid by at least partially opening the pressure control device and releasing drilling fluid into the bypass piping at a selected flow rate. The processor can modify the drilling fluid flow rate in the discharge piping based on the pressure represented by the pressure measurement signals and the selected flow rate in the bypass piping such that the target pressure parameter of the drilling fluid in the discharge piping is satisfied.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for regulating drilling fluid pressure, the system comprising: at least one surface drilling fluid pump connected to discharge piping connected to an inlet of the well bore, said pump operable to discharge drilling fluid through the discharge piping at a drilling fluid flow rate; a pressure control device having an inlet connected to the discharge piping and having an outlet connected to bypass piping; and a processor connected to the surface dr…
