摘要：沉积相研究是油气田勘探开发中一项重要工作，基于直井信息的沉积相研究技术较为成熟，但对于水平井沉积相的描述方法尚无成型经验。从水平井和直井的测井、录并资料及测井响应机理等方面进行了分析，建立了水平井和直并的电阻率关系，以储层“四性关系”为基础，构建水平并沉积微相判别图版，可以准确识别况积微相类型。在水平并储层分段精细描述的基础上，依据水平井分段判相结果，可有效地解决平面相带组合过程中存在的盲目性和多解性的间题。与单纯应用直并信息刻画相带进行对比，水平并参与相带组合，变相增加了并网密度，能够合理、准确地反映地下地质体情况，使砂体接触关系和储层平面非均质性描述更加清晰。在实践中探索形成的这套水平井沉积相捕述方法，对今后水平井高效开发具有重要指导意义，向实现精准地质研究目标迈进一步。

Abstract: The study of the sedimentary facies is an important work in the exploration and development of oil and gas fields, the research of the sedimentary facies based on the vertical well information is much more mature, but there is no experience in the description of the horizontal wells. Based on the analyses of the logging, mud logging data and logging response mechanism in both the horizontal and vertical wells, the resistivity relationship between the horizontal and vertical wells was established, and moreover on the foundation of the reservoir "Four Relation-ships", the sedimentary microfacies identifying board chart was mapped for the horizontal well, thus the types of the sedimentary facies can be accurately identified. On the basis of the fine segmented reservoir description of the horizontal well, according to the identification results of the horizontal well, the problems of the blindness and multi-solution in the process of the combination of planar sedimentary facies and belt can be effectively solved. Compared with the simple application of the vertical well information to characterize the sedimentary facies, after
