Jilin D Block Of Fine Reservoir Description Research

JiLin oil field D block mainly black emperor temple reservoir poor reservoir lateralcontinuity, oil and water distribution is very complex, short development production plateau,comprehensive water cut rising, the contradiction between the layers, mining harder, facedwith the problem of high and stable yield.To guide the black temple reservoir developmentmid and late adjustment, improve reservoir development effect, need to further analyze theblocks in the internal structure and characteristics of reservoir distribution and reservoirheterogeneity, the distribution of remaining reserves, for reasonable development adjustmentscheme, which provides the basis for the choice of the mining right way.This study aimed at JiLin oil field D block district black emperor temple Honggang oilfield have a poor reservoir property, thickness thin and serious problems such asheterogeneous, the integrated use of stratigraphy, sedimentology, petroleum geology, reservoirgeology and reservoir engineering and other multi-disciplinary theories and methods，usingstochastic modeling method to establish the r208district black emperor temple Honggang oilfield reservoir fine3d geological model, the real reflect the geological situation, lay thefoundations for the reasonable development of the reservoir; method using high resolutionsequence stratigraphy thickness contrast method, the traditional cycle, to construct the highresolution sequence between single well and well in the study area of geological structure, toovercome the past small layer thickness in contrast control limits and boundaries to wear,makes the contrast of small layer division is more reasonable; using reservoir heterogeneitybetween layers of research could be divided into3sets of the black temple reservoirdevelopment series of strata, distribution of single sand layer sandwich model is established;research results show that the plane heterogeneity: all the single sand body in the study area isof strong heterogeneity reservoir, all single sand layer is low permeability layer in thehole.This shows that the strong reservoir heterogeneity in the study area, The adverse impactof oilfield water injection development.
