江汉盆地盐间非砂岩储层特征及测井评价

江汉盆地盐间非砂岩储层是一类特殊储层。该类储层的特点是岩性复杂、储集空间多样、非均质性极强,储层评价困难。从岩心分析、地质录井、测井等基础资料入手,分析了该类储集层的储层特征,结合成像、核磁共振等测井新技术的应用,运用多种分析方法建立了该类储层的解释模型,并利用斯伦贝谢软件包“P包”等多种解释软件实现了盐间非砂岩储层参数的测井定量解释,形成了江汉盐湖盆地盐间非砂岩储层的测井评价方法;通过多口井的实际应用,效果显著。

Features and logging evaluation of inter- salt non- sandstone reservoirs in Jianghan basin

Inter-salt non-sandstone is a special kind of reser-voirs in Jianghan basin. They are characterized by complex lithology, multiple types of reservoir space and severe heterogeneity, thus reservoir evaluation is very difficult. The features of this kind of reservoirs are analyzed by using basic data such as core and logging. In combination with the application of new logging technologies, such as imaging and NMR, several analytical methods are used to build interpretation models of this kind of reservoirs. Several interpretation software packages including Schlumberger's "P- package" are used to quantitatively interpret the parameters of inter - salt non - sandstone reservoirs with logging data. A set of logging evaluation methods is presented for the inter-salt non-sandstone reservoirs in salt lake in Jianghan basins. Real application in several wells shows that they are effective.
