| 摘 要： | 从碳酸盐岩储层类型划分、储层参数表征、流体性质判别到数学方法的应用等4个方面,系统总结厘定了国内外碳酸盐岩储层测井评价的方法技术,通过对比分析各种评价方法可知:根据一定的数学算法,综合利用常规测井和成像测井不仅能很好地识别储层类型,而且能实现对储层参数的半定量、定量计算评价。利用常规测井和测井新技术资料(电测井和声波测井)计算出缝洞储层的各项物性参数,在此基础上,结合常规测井、核磁共振测井和偶极横波测井能进一步判别出流体性质。通过与岩心分析结果比较,该储层参数计算方法不仅有效,而且简单可行。数学算法和测井新技术资料在复杂碳酸盐岩储层评价中发挥不可替代的作用,能解决复杂碳酸盐岩储层的计算评价问题。以碳酸盐岩储层特征及流体性质为切入点,结合各种地质、地震和测井资料,借助数学算法,准确地识别储层类型与判别流体性质,并精确求解碳酸盐岩储层特别是缝洞储层的物性参数,将是碳酸盐岩储层测井评价的重点及发展方向。 |

| Abstract: | The logging evaluation methods and techniques on domestic and foreign carbonate reservoir were researched from the four aspects of reservoir type classification,parameter characterization,fluid property discrimination and mathematical method.After the analysis and comparison of various evaluation methods,it is considered that according to certain mathematical algorithms,not only the reservoir types were identified very well,but also the reservoir parameters were evaluated semi-quantitatively and quantitatively by the use of the conventional logging and imaging logging.The physical parameters of fracture cave reservoir were calculated using the data of conventional logging and new logging technologies(electrical logging and sonic logging),and on this basis,the fluid property can be discriminated by the conventional logging,nuclear magnetic resonance and dipole shear sonic logging.By comparison with the results of core analysis,this method for calculating reservoir parameters is not only effectiveness,but also simple and feasible.The mathematical method and the new logging technique data are very important for the complex carbonate reservoir evaluation,and can solve the calculation and evaluation problems of complex carbonate reservoir.Using reservoir characteristics of carbonate rocks and fluid properties as the starting point,with combination of geological,seismic and logging data,and mathematical algorithms,the reservoir types and fluid properties were accurately identified and determined,thus the physical parameters of fracture cave reservoirs(carbonate reservoirs) were accurately calculated,which were the focus and direction of logging evaluation on carbonate reservoirs. |
