ABSTRACT
The reservoir fluid mobility is essential for reservoir simulation, development, and production. It is a crucial parameter comprehensively reflecting rock permeability and fluid properties. In this paper, the seepage process of mud invasion into the formation around the borehole is analyzed and the characterization model of reservoir fluid mobility is derived. Based on the above, the reservoir fluid mobility estimation method computed from the array-resistivity logging is investigated. The new method is verified in Nanpu sag and the results show that the fluid mobility calculated by the new method is in good agreement with MDT tested mobility. Further, the new method calculated fluid mobility is applied to normalize the reservoir fluid mobility attribute computed from seismic data. The result shows that the normalized seismic fluid mobility can improve the accuracy of high-quality reservoir prediction. The estimation method of fluid mobility provides a new approach for the application of array resistivity logging and has good application prospects in seismic reservoir prediction, reservoir evaluation, engineering and production.
