塔中礁滩型碳酸盐岩储集层测井评价技术

针对塔中地区奥陶系缝洞型碳酸盐岩储集层特点,根据电成像定量处理的缝洞参数、常规测井参数,结合试油资料进行交会图分析,建立了不同类型储集层的定量分级标准,提出了泥质含量与面孔率比值定量评价洞穴型储集层“充填率”的新方法,确定了研究区洞穴型储集层有效性定量评价标准,研究了气测组分分析法、图版法、阵列声波参数交会法以及核磁共振测井四种流体性质判别方法。根据不同储集层特征进行了各方法适应性分析,建立了不同类型储集层测井与地震属性的关系,实现了微观与宏观相结合评价储集层的方法。

Well Logging Evaluation Technique for Reef-Flat Carbonate Reservoir in Tazhong Area,Tarim Basin

Based on the fracture-vug parameter from electric imaging quantitative processing,conventional well logs and formation testing data as well as crossplot analysis,the quantitative grading standard for various reservoirs is established,and new method of fill-up rate for quantitative evaluation of vuggy reservoir using shale content-areal porosity ratio is proposed.The fluid property discrimination approaches such as gas component analysis,chart analysis,array sonic parameter crossplot,NMR and their suitabilit...
