火成岩油藏测井解释评价思路及方法

Logging Evaluation Thought and Method for Igneous Rock Reservoir

针对火成岩储层测井评价难点,以三塘湖盆地牛东地区为研究目标,针对该区火成岩储层的地质特点、油层特征,对该区储层测井评价的主要难点进行分析,对火山岩岩性识别、有效储层的划分、裂缝性储层参数的定性定量评价方法及产能预测提出了新的见解、方法及处理流程,形成了牛东地区火山岩测井资料处理软件,并集成在ForWard软件平台上,通过实际应用与生产实际结合较好,取得了很好的应用效果。

In view of the difficuhies of logging evaluation for igneous rock reservoir, taking Niudong area in Santanghu basin as a research object, based on the reservoir geology characteristics and reservoir properties, the main problems about reservoir logging evaluation in the area are analyzed . New views and methods and processing flow about volcanic lithology identification , active reservoir discrimination , and qualitative and quantitative assessment methods for fractured reservoir parameter, and productivity prediction are raised, logging information processing software on volcanic rock in Niudong is shaped, which is integrated in ForWard software platform. After applied in the practice, it is combined well with production, with a good application effect.
