陕西关中盆地新生界储热层电性特征与测井资料分析——以R9热水井为例

Analysis on Electrical Performance Characteristics and Logging Data in the Cainozoic Heat-storage-layer of Guanzhong Basin in Shaanxi Province-Take R9 hot water well as an example

储热层由于其具有温度高、密度小(孔隙度大)等特点,尤其是在有基底隆起、断裂发育的情况下,会引起电、磁、重力及放射性等地球物理场的异常变化。这些变化所导致的异常就成为了解地下热储、圈定地热异常区、寻找地热田位置的重要标志之一。本文着重介绍关中盆地新生界储热层的电性特征及其与测井参数之间的关系。以其提高对测井资料的研究,更加合理的解释和划分储热层。

Because of some characteristics such as high temperature, small density （big porosity） etc. , especially in the case of foundation ridged, fracture developed, the heat-stored layer will set off many exceptional variations of geophysical field, such as electricity, magnetism, gravity and radioactivity etc. Those abnormities caused by the above variation are one of important symbols to understand underground heat storage, geothermic abnormity area confirmation and geothermic field position search. The article mainly introduces electrical performance characteristics in cainozoic heat-storage layer and the relations between the characters and logging parameters, to improve logging data studying and more reasonably explain and partition heat- storage layer.
