Abstract

The distribution of erosion trench of the Ordovician carbonate reservoir layers in the Shaan 200 region in Jingbian gas field is very complex.Due to the single distribution of the sedimentary microfacies,and lack of seismic data in the study area,the traditional facies controlling modeling is difficult to ensure the accuracy of reservoir modeling results.In order to accurately depict the distribution characteristics of the selected region,on the basis of previous studies,we divide the study area into three-phase including trench phase,reservoir facies and dry layer,and apply facies controling modeling to stochastic reservoir modeling.At the same time,since the logging permeability can not reflect the actual situation,we deduce the permeability,and apply it to deterministic modeling.By comparing the stochastic modeling and deterministic modeling,we want to determine the compliance of the two kinds of modeling methods.Studies have shown that the deterministic modeling is of better compliance with geological knowledge,and the error between modeling reserves and geological reserves is smaller,thus the deterministic modeling is suitable for the reservoir modeling in the selected area.It provides a sound basis for the optimization of horizontal well sites and gas reservoir evaluation at late stage.
