庙藏物理李一倩层老石的敏感桂研究 cemented type 1.basal cement cement composition is high and cemented type is body cementation.Because cement and sands sediment at one time,cementation intension is very strong
油藏物理学——储层岩石的敏感性研究 cemented type cement composition is high and cemented type is body cementation. Because cement and sands sediment at one time, cementation intension is very strong. 1. basal cement
油藏物理学一储层岩石的敏感桂研究 2.pore cement Cement composition is small and cemented type is area cementation Because cement was secondary,the cementation intension is inferior to basal cement
油藏物理学——储层岩石的敏感性研究 2. pore cement Cement composition is small and cemented type is area cementation . Because cement was secondary, the cementation intension is inferior to basal cement
3.contact cement Cement composition is a little and generally less than 5%.Because the cements only distribute the contacted surface of sand and is point or line contact,the cementation intension is poor

油藏物理学——储层岩石的敏感性研究 Sensitivity of reservoir velocity sensitivity； water sensitivity——salt sensitivity； acid sensitivity——alkali sensitivity； heat sensitivity——cold sensitivity； pressure sensitivity——temperature
velocity sensitivity higher injection velocity result that fine grain motion and rock permeability decrease greatly. Example:kaolinite,isinglass et
