储层客观存在的非均质性,是决定开发战略和一系列技术政策的重要依据,储集层综合评价和分类又是认识和区分储集层非均质性的重要工具和手段,本文利用模糊综合评判数学模型方法,选取均砂岩厚度,平均有效厚度、平均渗透率、变异系数、油砂体钻遇率5个评价参数,对尕斯库勒油田N1～N_2~1油藏北区块储层进行模糊综合评判,将该油藏储层划分为三个大类、9个亚类,尕斯库勒油田N1～N_2~1油藏北区块储层主要为二类油藏储层。
The objective heterogeneity of the reservoir is an important basis for determining the development strategy and a series of technical policies. The comprehensive evaluation and classification of the reservoir is also an important tool and means to recognize and distinguish the reservoir heterogeneity. In this paper, Fuzzy comprehensive evaluation mathematical model method, the sandstone thickness, the average effective thickness, the average permeability, the coefficient of variation and the drilling rate of the oil sand body are selected to evaluate the comprehensive evaluation of the North Block N1 ~ N_2 ~ 1 in Gaskule Oilfield Reservoir fuzzy comprehensive evaluation, the reservoir is divided into three major categories, nine sub-categories, gas reservoir in the West Block N1 ~ N_2 ~ 1 gas reservoirs north of the reservoir are mainly two types of reservoir .
