The Second Class Reservoir Studies To Develop The Effect Of Polymer Flooding And Polymer Injection Technology To Stop

Development Zone in the north of Saertu the first class in the polymer flooding blockshave been in the late period of polymer flooding and subsequent water flooding stage, thesecond class reservoir become the main direction of efficiency and stable polymer flooding.Compared with a reservoir, two types of reservoir has the characteristic of "thin, low, narrow,poor", and in the inner layer, interlayer contradiction prominent, phase changes complex inlevels. Since the two types of reservoir heterogeneity is serious, after low moisture pick-up offast and effective large differences. Therefore, the need to constantly enrich and perfect thesecond class of polymer flooding reservoir comprehensive adjustment technology andpersonalized adjustment means to explore the second category Polymer Flooding efficientdevelopment patterns to maximize recovery.Contents of this paper is to establish the North West block two second class reservoir15sedimentary units,323oil wells on the basis of geological modeling to determine the secondcategory reservoir history matching and sorting through the data, such as numericalsimulation techniques to predict stop polymer injection timing. Through the simulationof oil recovery, the wells are divided into5categories, determine the types of well stoppolymer injection timing and established standard curve of various wells. Building a fourproduction theory model, the numerical simulation of oil reservoir development reservoirheterogeneity into the contribution of oil saturation concentration measures on the effect ofsingle well development value and establish different types of standard curve of well.
