Analysis Technique Research On The Intraformational Bed Of Extra High Water Cut Stage In Lamadian Oilfield

Sandwich is lithology of reservoir and oil-bearing occurrence level reduce the description of the reservoir. Identify interlining and divides interlayer thickness on the precise calculation of reserves, describe reservoir fine geologic characteristics, the research and analysis of remaining oil is of great significance. Found in recent years, in strict accordance with the thickness and interlayer divided operation rules, since oilfield development by the number of row mezzanine has a tendency to increase year by year, especially since2005, north north block of polymer flooding back on new drilling divided by intercalation significantly increased, caused by different development periods delimit interlining matching sex becomes poor, affects the interlining own tracking contrast, don’t judge of sedimentary facies, perforation scheme establishment, many aspects, such as fine geologic research, new Wells mezzanine lamadian oilfield so will divide the method study as the main content of interlining to explain. At the same time, the interlayer of the control action of injected water and residual oil distribution are known and valued people increasingly, so the interlayer permeability lithologic identification, evaluation and become very meaningful, therefore to carry out the study.
