Abstract

Nuclear magnetic resonance was used to test core pore size distribution and whole-rock X-ray diffraction analysis was conducted to understanding the relationship between physical properties and formation water mobility and determine the formation water mobilities under different physical properties in tight sandstone gas reservoir.A new method for formation water mobility classification by combining with centrifugalizing and nuclear magnetic resonance was proposed to analyze the relationship between porosity,permeability,pore structure,rock mineral composition and formation water mobility. Result indicates that there is no absolute limit for the movable or immovable water, and the formation water mobility is greatly dependent on the reservoir pore structure.Mineral composition shows little effect on the formation water mobility.It is believed that the formation water can be classified into bound water, movable bound water and movable water,while there is no absolute limit for the classification of bound water saturation,movable bound water saturation and movable water saturation.The corresponding approximate values can be gained through laboratory experiment test.This research could provide certain guidance for the tight sandstone gas reservoir development and reduction of formation water production risk.

Key words： tight sandstone gas reservoir; formation water mobility; nuclear magnetic resonance; bound water saturation; Ordos Basin
