研究区瓦窑堡油田中山川区属鄂尔多斯盆地陕北斜坡东部，长6油层组是其最重要的含油层位之一。近几年随着鄂尔多斯盆地油藏勘探和开发取得的突破性进展，其储层精细分析与评价显得更为重要，而测井资料是储层评价的重要手段。本论文从基本地质条件出发，利用岩芯观察、铸体薄片、电镜扫描、压汞分析等各种储层研究的实验和技术，在对该区长6油层组基本地质特征等研究基础上，系统分析重点井的岩性、物性及含油性的测井响应特征，详细研究了储层的含油性、岩性、物性和电性，并对储层的“四性” 关系进行了测井评价。在此基础上，应用测井资料结合基础地质资料，建立了低孔特低渗油藏测井储层参数解释模型及其适用于低孔特低渗油藏的油层识别方法。 依据低渗透油田分层评价标准，对研究区储层进行了综合评价，圈定了有利储层分布范围。研究成果对瓦窑堡油田后期开发具有一定的指导作用。

The Zhongshanchuan research area of Wayaobao Oilfield is located in the Shanbei slope of the Ordos Basin, Chang6 oil layers is the most important one of the oil-bearing strata. In recent years, with the breakthrough progress of exploration and development in Ordos Basin, the sophisticated analysis and evaluation about reservoir turn to be more important, and the logging data is an important method of reservoir evaluation.This paper launches the research starting from basic geological conditions,with the core observation, cast thin section, scanning electron microscopy, mercury injection analysis study of a variety of experiments and reservoir technology. According to the foundation of research about basic geological features etc for Chang6 oil layer in this area,the paper makes the systemic analysis of lithology, physical properties and oil characteristics of the log response for the key wells, do a detailed study to the oiliness, characters of lithology, physical properties and electricity of the reservoir,and put up the evaluation of the logging for the relationship of four properties of the reservoir. On this basis,with the application of the logging data combining with the basic geological data, the establishment of a low porosity and low permeability reservoir reservoir parameters log interpretation model and its application in low porosity and low permeability oil reservoir identification. Based on low-permeability oil layered evaluation criteria, We made the comprehensive evaluation of reservoir and delineated the distribution range of favorable reservoirs. The research results are guiding roles on the late development of Wayaobao Oilfield.
