摘要

本文根据微孔隙表面具有吸附及凝聚的原理,通过ST-03型比表面、孔径测定仪,测定微孔的吸附、脱附等温线,利用其形态及对吸附量的研究,判断天然气盖层微孔隙的形态并对孔隙和裂缝加以区别,为油气的初次或再次运移研究打下基础。

Abstract

On the basis of the principles of existance of adsorption and condensation on the sur-face of micropores,the authors obtain the adsorption and desorption isotherms of microp-orosity through the measurements by using the ST-03 type specific surface pore diame-ter.By use of their geometry and the research results of adsorbed capacity of microporosi-ty,they decide the microporous geometry in the capping-beds of natural gas and make adistinction between pores and cracks in order to lay foundation for studying the primaryand post-primary migrations of oil and gas.
