| 摘 要： | 偶极横波成像测井受地层水矿化度的影响很小，在高阻（淡）水层、低阻（高矿化度）油气层评价中有独特的优势。通过对川东北地区碳酸盐岩储层偶极横波成像测井气水识别方法的研究，总结了该地区碳酸盐岩储层气水层定性识别的标准，并得到了相关参数、气水识别的判别值和交会图图版。对该地区的两口井，在常规测井解释与测试结果不相吻合的情况下，特别进行了偶极横波成像测井资料综合分析，得到的解释结论与试油结果吻合，说明在该地区偶极横波成像测井在气水识别方面与其他测井资料相比优势较明显。

| Abstract: | Dipole shear wave formation micro imager (FMI) log is little affected by formation water salinity, therefore it has unique advantages in the evaluation of high resistive water bearing formation and low resistive hydrocarbon formation. We studied gas and water discrimination problem in carbonate reservoir with dipole shear wave FMI log in northeastern Sichuan. Some rules and thresholds were established and crossplot templates were made to distinguishing gas from water in carbonate reservoirs. The interpretation results from dipole shear wave FMI log in two wells are confirmed by testing for oil where the interpretation results from conventional logs failed. |
