US Patent:

45358516, Aug 20, 1985

Filed:

Mar 9, 1983

Appl. No.:

6/473645

Inventors:

Lloyd V. Kirkpatrick - Beaumont TX
John R. McGee - Simonton TX

Assignee:

Kirkpatrick-McGee, Inc. - Houston TX

International Classification:

E21B 2108
E21B 4400

US Classification:

175 38

Abstract:

A system, or apparatus combination, and apparatus components, for the measurement of fluid flow. Such system, or apparatus can be used, e. g. , for measuring the amount or flow of drilling fluid, or mud, introduced into a well bore, the amount or flow of mud returned from the well bore, and differences in flow rate and density between the mud introduced into the well bore and the mud returned from the well bore. The system measures or calculates, inter alia, flow rates, viscosity, temperature, density and gas content and compensates for variations; and in marine installations the system additionally measures vessel motion and compensates for wave and tide motions. The system includes on the mud input side one or more measurement primaries for the measurement or calculation, inter alia, of flow rates, viscosity, temperature and density, and on the mud return side a gas monitor is provided for the measurement and compensation of gas contained within a multiphase mud slurry returned from down-hole, and one or more measurement primaries for the measurement or calculation, inter alia, of flow rates, viscosity, temperature and density. For semi-submersible or floating marine installations vessel motion is measured. The system includes one or more computers.
