摘　　要：歧口凹陷普遍发育湖相碳酸盐岩储层,该类储层纵向发育稳定,横向分布广泛。由于该类储层岩性复杂,储层空间多样,利用常规测井解释方法无法有效开展储层流体性质识别。针对这一难题,本文在综合分析目的层沉积特征基础上,确定了颗粒滩、云灰湾和云坪等沉积微相测井曲线形态和测井响应特征,利用测井资料有效开展沉积微相划分与识别。在此基础上建立了基于沉积微相分析的湖相碳酸盐岩储层流体性质识别方法,实际应用表明取得了很好的效果。The general development of lacustrine carbonate reservoir in Qikou Sag, This kind of reservoir has a stable vertical development and wide horizontal distribution. Because of the complex reservoir lithology and the diversity of reservoir space, the reservoir fluid properties can not be identified effectively by conventional logging interpretation methods. To solve this problem, based on the comprehensive analysis of sedimentary characteristics, determine grain-shoal facies, Grey Bay facies and cloud depression logging response characteristics and logging curve shape, Using well logging data to effectively carry out the classification and recognition of sedimentary microfacies. On the basis of this, a method for identifying fluid properties of lacustrine carbonate reservoirs based on sedimentary microfacies analysis is established,The practical application shows that good results have been achieved.
