雁木西油田出砂机理研究与应用

THE STUDY ON SAND PRODUCTION MECHANISM: TAKEN YANMUXI OIL FIELD AS AN EXAMPLE

随着雁木西油田开发的深入,主力层出砂不断加剧,严重影响了油田的正常生产。油田主要含油层(?)第三系和白垩系储层岩性以细砂岩为主,胶结方式以钙质胶结为主,泥质含量较高。通过对雁木西油田出砂机理分析、出砂预测及储层敏感性评价,总结出油田出砂规律,进而提出油田生产过程中防砂的指导性建议。

As the development of an oil field goes further, the sand production from major pay zone becomes severer and severer, which affect the normal production seriously. The major oil-bearing layers of Yanmuxi oil field in Tulufan region are Tertiary and Cretaceous. Lithology of the reservoirs is mainly sandstone, and consolidation mode mainly calcite cementation with relatively high shale content. Sand production regularity of the oil field was recognized through mechanism analysis and prediction, and reservoir sensitivity evaluation. Instructive suggestions for preventing sand production were put forward.
