Experimental investigation of flow of shear thinning liquids through an annular channel with centrebody rotation. 1. Provision of data regarding influence of centrebody eccentricity and rheaology for conventional drilling geometry. 2. Development and application of a torquemeter for conventional and slimhole geometries. The first objective is to clarify the combined influence of centrebody ( drillpipe ) eccentricity and fluid rheology on pressure drop for flow through an annular geometry typical of conventional drilling. Pressure drop versus flowrate measurements will be supplemented by LDA measurements of axial and tangential velocity components and turbulence intensities for selected combinations of eccentricity, centrebody rotation speed, flowrate and fluid rheology. The second objective is to develop and use a novel instrument to measure the torque caused by the presence of liquid flowing through a concenric annulus, with emphasis on a narrow annulus representative of the slimhole drilling configuration. Some aspects of the deliverables of both elements of the programme have direct relevance to field operations in the oil and gas industry, while the more detailed results will assist the development and validation of basic CFD codes and also design codes. The work is an extension of current research, and will use existing equipment and require no further capital investment thanks to financial support from BP Research Centre and Shell Research.
