Background technique
Oil field needs continuous Study of The Underground oil reservoir oil-producing situation in recovery process, to keep oil well steady in a long-term, high
It produces, improves oily well yield using water flooding regime in most oil fields at this stage, therefore must just pass through formation testing side in advance
Method understands the adsorption capacity of Different Strata, finally determines the number of water injection rate again；This test method is: from well head in well
Isotopic carrier is poured into, after adsorbing the stratum with different adsorption capacities, then to entire injection well section radioactivity logging device
The shortcomings that device measures, and use well head directly pours into isotopic carrier in well is: first is that since casing back pressure is larger, together
The plain carrier in position is not easy to pour into, so that causing the pollution of full well section, measured isotopic curves is made to be not easy correctly to distinguish ground
Layer water absorption.Second is that pouring into due to full well section, it can be difficult because of sucking for hyposmosis target zone, it cannot be just on experiment curv
True reflection water suction situation.
