Zhou 13 Block Oil Recovery Ratio Numerical Simulation Study In Daqing

Based on the geological sediment environment and the structure characteristic of the Zhou 13 region,compartmentalized the reservoir strata.Compartmentalized oil layer into mbrs by the sedimentary facies and naming.We have describing the container rock properties and physics properties,comprehending the underground hydrodynamics,combining the basic data which had attained when drilled well,confirming the effective thickness,studying the size and conformation of the oil layer sandstone,calculating the reserves by using the volumetric method.Chosen the driving form of the petroleum deposit and the exploitation technique of the well by the flowing meanings:collecting the geological characteristic of the area,the pressure and temperature system,and the originality oil saturation,combine with the basic datum of the test region in the oil field and the practical datum of the producing well,comparing with the similar field which are parallel in the characters of the oil layer and the practical datum.By using the result of the numerical reservoir simulation,affirm layer series of development,injection-production pattern,well density,and when change to inject.Using the result to make the development plan,and forecast the index of exploitation.
