录井、测井结合评价储集层方法研究

Combining mud logging with wireline logging to evaluate reservoir

录井、测井从不同角度发现与评价储集层都有各自的优势,从井场信息集成的角度,将录井、测井信息结合,发挥各自优势,进行综合评价,应是井场信息集成发展的一个方向。在分析不同储集层录井、测井参数特征的基础上,探讨了吐哈盆地录井、测井结合评价储集层的方法,即相当油含量与孔隙度结合评价法和相当油含量、孔隙度和渗透率结合综合评价法,给出了各自的解释评价方法图版,介绍了解释评价图版的应用效果,经初步应用统计,其解释评价符合率达到80%以上。该方法的研究与应用对指导井场信息集成与综合化处理和解释具有指导意义。

In discovering and evaluating reservoirs, mud logging and wireline logging have superiorities respectively from different angles. From the point of wellsite information integration, combining mud logging information with wireline logging information and bringing their own superiorities into full play to conduct comprehensive evaluation should be a developing trend of the wellsite information integration. On the basis of analyzing the characteristics of mud logging and wireline logging parameter from different reservoirs, the paper approached the method of evaluating reservoirs in combination of mud logging with wireline logging at Tuha region, that is, the evaluation method of combining equivalent oil content with porosity, comprehensive evaluation method of combining equivalent oil content with porosity and permeability. The interpretation and evaluation charts of each method and their application results were given. By initial application and statistics, their interpretation and evaluation coincidence rate was up to or more than 80 per cent. The study and application of these methods would have guiding significance in the wellsite information integration and comprehensive processing and interpretation.
