非均质碳酸盐岩储层及产能评价方法探索

非均质碳酸盐岩储层的定量评价以及产能预测一直是测井分析中难以解决的问题，利用成像测井、核磁共振测井和偶极声波测井等资料分析了非均质储层特征，通过核磁共振测井分析了孔径大小及其与渗透率的关系，介绍了如何利用POROSPECT计算结果来描述原生、次生孔隙度，并研究了成像测井和核磁共振测井定量描述非均质储层的方法，较好地探索了孔洞缝发育程度、总孔隙度、次生孔隙度、渗透率、孔径大小与产能的关系以及利用核磁共振、成像测井评价产能的适应性，效果明显。

Heterogeneous Carbonate Reservoirs and the Productivity Evaluation

The quantitative evaluation and productivity prediction of heterogeneous carbonate reservoir is keeping a hard-solved problem in well logging analysis,the characteristic of heterogeneous reservoir is analyzed by using such data as imaging logging,NMR logging and dipole sonic logging,the pore size and the relation between the size and permeability are also analyzed with NMR logging,the application of POROSPECT calculation result in describing primary and secondary porosity is introduced,the approach quantitatively describing heterogeneous reservoir with imaging logging and NMR logging is studied,the development degree of pore,vug and fracture,the total porosity,secondary porosity,permeability,the relation of pore size and productivity,as well as the suitability of evaluating productivity with NMR logging and imaging logging are all studied.
