摘　　要：为研究开发萨零组油层的可行性,利用模糊综合评判方法对喇萨杏油田萨零组油层进行了综合评价。评价标准采用目前公认的行业标准和经验判断标准,选取流体物性、砂岩发育程度、微观孔隙结构特征、岩石敏感性、储层物性等作为评价参数,通过实际资料与标准对比,得出单因素评价矩阵。依据单一因素对油藏开发效果的影响,确定相应的权重系数,并应用模型计算出最终评价矩阵。根据最大隶属原则判定萨零组油层属于“差”的水平。In this paper the fuzzy comprehensive estimation method is utilized to evaluate the reservoir of Sa 0 sets. The fluid property, growth degree of sandstone (ineluding mean thickness of individual sandstone layer and probability of penetration of the thicknees of sandstone layer) , architectural features of microscopic pores, geo-logical reserve, rock sensibility and reservoir physical properties (ineluding mercy drainage efficiency, homogenous coefficients of porous structure, permeability and coefficient of permeability varia-tion) are chosen as evaluating parameters. After comparing those matter-of-fact with corresponding standards, individual factor evalu-ation matrix is derived. The corresponding weight coefficient is de-termined aecording to the effect of each individual factor on the reservoir development. The final evaluation matrix is figured out with the application of improved hierarchical model. After the evalua-tion, Sa 0 sets is evaluated to he a poor reservoir according to the maximal grade of menlbership principle.
