Study on reservoir features on Eh3 Ⅶ oil group in Shuanghe oilfield
-
Abstract
Reservoir distribution and positional changing law of petrophysical property are analyzed and described from as- pects of lithology,pore type,structure feature,interbed dis- tribution and reservoir anisotropy,by applying reservoir ge- ology and using drilling,core analysis and log interpretation knowledge.It yields that both sedimentary facies and inter- bed distribution control reservoir anisotropy.Effects show that,reservoir in study area is featured of medium pore,me- dium to high permeability,thin to thinner throat and heavy anisotropy;petrophysical property differ from every sedi- mentary facies.To fully understand features of Eh3Ⅶres- ervoir provides geological evidence to further development of the area.
