摘要
塔中地区奥陶系缝洞型碳酸盐岩地层比较发育。在测井资料逐渐增多、露头和岩心资料不足、地震资料分辨率有限的情况下，利用测井方法进行缝洞型碳酸盐岩储层的识别与预测显得越来越必要。为此，通过对自然伽马、双侧向电阻率、FMI、自然伽马能谱等测井参数的综合分析，总结了该区缝洞型碳酸盐岩储层的测井响应特征，以塔中卡1区块中17井为例阐述了缝洞型储层的测井综合解释方法，再结合钻井、气测、岩心等各项基础资料，进行了地层的纵横向对比，从而针对塔中卡1区块奥陶系缝洞型碳酸盐岩有利储层进行了预测。用此测井综合解释方法成功地解释了中1井，油气测试和岩心、试油资料都证实了此方法的有效性和合理性。
Ordovician fractured-vuggy carbonate formation is relatively developed in Tazhong area. As a result of the gradual growth of logging data, shortages of outcropping and rock core data , and restricted seismic resolution, it becomes more and more necessary to identify and predict fractured-vuggy carbonate reservoir by well logging method. Therefore, this article summarizes the log response characteristics of fraetured-vuggy carbonate reservoir by analyzing GR, DLL, FMI and SGR etc. comprehensively, then illustrates log interpreting method of fractured-vuggy reservoir by taking Well Zhong-17 of Block Tazhongka-lfor example, correlates strata vertically and horizontally on the basis of combining drilling well, gas logging, rock cores and other basic data, and finally predicts favorably Ordovician fractured-vuggy reservoirs in Block Tazhongka-1. Well Zhong-1 has been successfully interpreted by using this comprehensive approach. In a word, the validity and rationality of the above method have been proved by data from oil and gas testing, rock cores and production test.
