摘要
裂缝性储层因其特有的岩石物理特性 ,利用现有的地震资料及常规测井资料很难搞清其内幕构造、储集空间分布、孔隙类型、储层发育带与构造位置的关系等。但利用成像、核磁共振测井资料却可取得较好效果。首先在综合钻井、录井、测井、试油、岩芯资料的基础上 ,用岩芯标定、刻度测井资料 ,利用测井资料建立岩石的测井响应 ,识别岩性 ;其次 ,在标定和识别岩性的基础上 ,利用声电成像资料识别各种裂缝、孔洞 ,并综合其他成像资料判别其裂缝有效性 ;最后 ,结合核磁共振测井资料建立测井解释模型 ,对储层参数进行定量计算 ,在定量评价的基础上 ,综合各种信息对流体进行识别。埕北 30潜山碳酸盐岩储层采用此方法进行评价 ,发现其主要储层为古生界的八陡组、冶里 -亮甲山组、上马家沟组。
It is difficult to understand the internal structure, the reservoir space distribution,pore types,the relation between reservoir development zones and the localities of structures of fractured reservoirs only using seismic and well log data.But imaging and nuclear magnetic resonancelog can help us to get good results.Based on the data of drilling,log,well log,well test and core,core calibration and graduation log data were used to set up log response and make rock discrimination, then use acoustic image to identify fractures,pores and cavities as well as their efficiency, finally use nuclear magnetic resonancelog data to set up well log interpretation model, quantify reservoir parameters and identify the fluids in reservoirs. This method was used in the assessment of carbonate resevoirs of Chengbei 30 buried hill,the results are satisfactory.
