摘要
新安边地区长7油藏受沉积环境控制，砂体横向变化快，纵向隔夹层发育，主力贡献层识别难度大。通过综合应用数理统计法和岩心观察、常规测井、核磁测井识别法，建立了主力贡献层纵向识别标准，应用该认识指导水平井轨迹设计优化．取得了较好的应用效果。
Controlled by the depositional environment, the sand body of Chang7 reservoirs in the Xin＇anbian region laterally varies quickly, anti develops between intedayers longitudinally. The main contribution reservoirs are difficult to he identified. A standard of longitudinal identification of main contribution reservoirs is established in the paper through the integrated application of mathematical statistics, core observation, conventional logging, and NMR logging identification methods. To apply this knowledge to guide the optimization of horizontal well trajectot7 design, good practical effects are achieved.
