Abstract
After years of water injection, the underground movement of oil and water in Daqingzijing oilfield is becoming more and more complex, and the distribution of reservoir parameters between wells and remaining oil is difficult to predict. The reservoir geological model of H56 block in Daqingzijing oilfield is established with the support of numerous data by applying stochastic modeling techniques; it effectively reproduces the reservoir heterogeneity and distributes parameters in uncertain area between wells. A sequential indicator simulation algorithm is used to simulate the sedimentary facies, and facies-controlled reservoir characteristics have been performed including the reservoir petrophysical parameters and variability in the wells. In order to verify model accuracy, a comparison of porosity and permeability between model data and actual data is essentially made, the fitting of reserves and the original reserves were compared, and the whole field and the single well between the model and the history data were compared; the model shows consistency that gives confidence in using the model for numerical simulation purposes.
