A STUDY OF WATER SENSITIVE INDEXES DURING OIL FIELD DEVELOPMENT

The study of water sensitive indexes may effectively influence development of an oil field.By comparing the experimental data of water sensitivity in Wennan oil field,a relationship among water sensitive indexes,rock air permeability and salinity of injected water was set up.It is showed that there was very high level of association with each other.The relational expression can be used to predict the possible water sensitivity of different rocks and different injected water in the area.It may also have some indication for other oil fields during waterflood development.
