Problems of capillary pressure definition in samples of rocks by centrifugation method (part 1)

Authors: A.M. Svalov (Oil and Gas Research Institute of RAS, RF, Moscow)

Key words: capillary pressure, centrifugation method, data processing.

In paper laws of expulsion of wetting fluid from samples of rocks are investigated at centrifugation method application for capillary pressure definition. It is erected, that at a standard centrifugation method achievement of the capillary pressures exceeding one atmosphere is physically impossible. Advancing of the method envisioning increase of initial stress in core holder of a centrifuge is offered. Abundant errors are analyzed at interpretation of centrifugation data and the method raising reliability of treating of these data is tendered.
