摘　　要：在油田开发早期阶段,首批开发钻井结束后综合应用地质、电测井和波阻抗反演成果进行了精细地层对比,识别单砂体并确定井间边界,提出了建立单一河道砂体骨架模型的方法和途径,并提取了有关宽度、宽厚比等参数。与试井解释及同类型河道砂相关露头研究成果相比较,证实了该单砂体模型具有较好的合理性。将单砂体模型应用于井间加密钻井获得了成功。以该模型为基础,建立了三维油藏模型,优化了水平井钻井设计,成功地钻穿了预测的河道砂体,水平段钻遇率达到84.7%。The modeling method and procedures for single channel sandbody framework suitable for oilfield development in the early stage after drilling first batch development wells were discussed. The modeling methods include detailed reservoir correlation, identifying of single sandbody and determination of inter-well boundary by integrating data of geology, electric logging and acoustic impedance inversion. The quantitative geological parameters, such as width of single-channel sand, ration of width to thickness, were extracted. Compared with the results from well test interpretation and outcrop study with similar depositional characteristics, the single channel framework model is valid. This framework model was successfully used to drill of a new infilling development well. A 3-D reservoir model was developed on the basis of the framework model and further utilized to optimize the design of horizontal well. The predicted channel sandbody was penetrated with the encountering channel sand rate of 84. 7% in the horizontal section.
