Fluid Identification Study Of Low Porosity And Low Permeability Reservoir Of The Southern Sorigliao Basin

In the southern Songliao Basin in recent years, as the representative oflow porosity and low permeability oil layers, complex reservoir of lithologycontrol more and more found. These area resource is large in scale, is themain battlefield of oilfield production.However, due to the complexity ofthese regions of the reservoir, the oil-water layer identification difficult, andcaused great difficulties to the reservoir evaluation. Daan North region isfound with the above characteristics of the reservoir these two years, itsperformance for low porosity and low permeability, complicated oil-waterrelationship, reflecting the boundaries of the oil-water layer curve is notobvious. Therefore, based on the summary of the reservoir macroscopicGeological law analysis, focused around geological features of theseareas,to carry out the study of reservoir characteristics, deepen thereservoir awareness, research the macro and micro genesis of lowporosity and low permeability reservoir. Application of large amount ofdata of Heidimiao, grape flower, Gaotaizi oil layer and water layeridentification technology effectively, form a set of low porosity and lowpermeability reservoir fluid identification method with high precision, toaccelerate the pace of exploration and development of oil fields and oilreservoir evaluation provides the basis.
