成像测井技术在裂缝储层评价中的应用

Application of image logging to fractured reservoir evaluation

对成像测井应用于裂缝储层岩性解释、裂缝评价的方法进行了分析 ,并对其在沉积相分析、井旁构造分析、裂缝展布及地应力分布规律分析等方面的应用进行了描述。应用结果表明 ,成像测井能提供详细而丰富的储层及地质信息 ,可直接用于裂缝的识别及其有效性评价 ,计算储层裂缝孔隙度、裂缝开度等参数 ,还可以通过多井评价应用于储层精细结构和沉积环境研究。

The methods that the image logging is applied to explanation of lithology and evaluation of fractured reservoirs are analyzed and the applications about analyses of depositional facies, wellside structure, fracture extension and distribution rule of earth stress are described. The result shows that the image logging can provide detailed and rich information of reservoirs and geology and can be directly used in fracture identification, evaluation of validity and calculation of fracture parameters such as porosity and fracture opening. Through multiwells evaluation, it can be used in the research of fine reservoir structure and depositional environment.
