Variation regular and influencing factors of pore and permeability parameters of each oil layer of block A

Abstract

The porosity and effective permeability values of an oil layer in different periods of the same block are quite different, It is proposed to take the actual production target interval and small block in block A as the unit, by analyzing the results of laboratory water flooding experiments and using the data of coring wells and exploration wells in the study area, as well as the data of static database, the variation rules of porosity and effective permeability in different development stages are summarized. After comprehensive study, it is found that the change of parameter interpretation model and water injection development are the main factors for the change of hole and permeability parameters of well completion logging interpretation in different periods in block A.
