摘　　要：影响特低渗油田油井产能的因素较多,核心因素为储层孔隙空间、渗透率和含油性。以姬塬油田H195井区为例,通过初期产能与各测井参数相关性分析,寻找能反映储层特征的测井参数,建立产能系数法和综合指数法产能预测模型。通过对2种方法计算结果进行综合分析,将产能预测技术从单井转向单砂层,得到层内连续的产能评价参数,以此优选主力层及主力贡献段,指导水平井轨迹设计。There are many factors affected the production of low permeability reservoir, among which the reservoir pore space, permeability and oiliness are the main factors. Taking H195 well field as an example, through correlation analysis of logging parameters and initial productivity, this paper obtained the main logging parameters that can reflect the reservoir characteristics, and established productivity prediction models of productivity coefficient and aggregate index. By analyzing the results of the two methods, we turned the productivity prediction technology from single well to single sand layer, obtained successive evaluation parameters of reservoir productivity, and then optimized main layers and main contributed parts, which could guide the design of horizontal well trajectory.
