Abstract

Based on high-speed centrifugal gas-water displacement experiment using NMR and low-temperature adsorption experiment for typical tight reservoir parallel cores of Tarim and Ordos basins.The study obtained total bound water saturation,specific surface area and ratio of micro-pore of the reservoir quantitatively,which are used for the establishment of analytical method of bound water film thickness.Research results show that,with high-speed centrifugal gas-water displacement experiment using NMR and low-temperature adsorption experiment,this study distinguishes capillary bound water and bound water film effectively,which provides a new method for calculating thickness of bound water film accurately.Distribution range of thickness of bound water film in this study is 4.92-38.94nm with an average value of 12.88nm,which is smaller than that of the traditional high permeability reservoir which is about 50nm.The lower permeability the reservoir has,the higher bound water film thickness the reservoir gets,the smaller effective throat radius and seepage flowing pore space the reservoir owns,the more boundary layer effect and nonlinear characteristics of fluid flow the reservoir exist.
