江汉盆地盐间非砂岩储层特征及测井评价

Evaluation on Characteristics of Non-sandstone between Salt Beds of the Jianghan Basin and Logging

江汉盆地盐间非砂岩储层是一类特殊储层。该类储层岩性复杂、储集空间多样、非均质性极强、储层评价困难。应从岩心分析、地质录井、测井等基础资料入手,分析该类储集层的储层特征,并结合成像、核磁共振等测井新技术的应用,建立该类储层的解释模型。此外,还要辅之以“P包”等多种解释软件实现盐间非砂岩储层参数的测井定量解释,以形成江汉盐湖盆地盐间非砂岩储层的测井评价方法。

Non-sandstone between .salt beds, characterized by complex lithology, various reservoir space and severe heterogeneity, is a type of unique reservoir and difficult to evaluate. Started with basic data such as core analysis,geological mud logging and well logging, the characteristics of the reservoir has been analyzed. Combined with the application of new well logging technology such as FMI,CMR, interpretation model of the reservoir was set up by using various analyzing methods. Petrophysics software package has been used to quantitative analyzing of the logging parameter of non-sandstone between salt beds, hence to develop logging evaluation method and obtained a satisfied result in practice.
