裂缝性储层电成像测井孔隙度定量评价方法研究

根据双孔介质孔隙解释模型概念,建立计算裂缝性储集层孔隙度参数(总孔隙度、基质孔隙度、孔洞孔隙度、裂缝孔隙度)的系统方法,为裂缝性储集层解释及储集类型的划分提供了新的思路.在双孔介质储层中,利用电成像测井资料定量分析储层孔隙度,确定储层孔隙类型;在利用电成像资料处理和评价裂缝性储层时,要结合常规测井资料,充分发挥常规测井探测深度深、电阻率成像测井分辨率高的特点来准确评价裂缝性储层.

Fractured Reservoir Porosity Quantitative Evaluation Using Electric Imaging Logging Data

Based on dual-porosity explanation model,we set up a calculating method of fractured reservoir porosity parameters(such as total porosity,basic porosity,vug porosity and fracture porosity).It is a new way to explain the fractured reservoir and partition the types of reserve.In the dual-porosity reservoir,we quantitatively analyze reservoir porosity by electric imaging logging datum in order to determine the types of reservoir porosity;When dealing with and analyzing the fractured reservoir by electric imaging logging data,we integrate general logging datum,which can completely displays the advantages of deep investigation depth of traditional logging and the high resolution of electric imaging logging to exactly analyze the fractured reservoir.
