THE STUDY ON THE RETRO-MERCUROMETRIC EFFICIENCY OF ROCKS
-
摘要: 室内实验研究表明,岩样中枯土成分及其含量、胶结物中可连通的微细孔隙的多寡、岩样表面性质的差异是影响退汞效率的重要因素.从油藏宏观观察,退汞效率随油藏深度的加大呈上升趋势,与岩样孔、渗和水敏性有良好的对应关系.Abstract: The experimental study has revealed that the clay composition and its content in rock samples,the number of the linkable minipore in cement and the difference of the surface properties of rock samples are the key factors of retro-mercurometric efficiency.In view of the development of oil/gas pools,the retro-mecurometric efficiency wouldtake rising trend along with the increasing depths of oil/gas pools and show good corresponding relations with the pores,permeabilities and water-sensitivities of rock samples.
